VAZ-2112 became the last in the line of the 10th model. This is modern and dynamic car, in which operational as well as external indicators have significantly improved. It is worth saying that this is the best-selling car. Buyers are attracted low prices, excellent maintainability, as well as high practicality.

Model history

Tenth family front-wheel drive models The Volzhsky plant began in 1995, with the 2110 sedan model. Then, in 1998, the plant launched the assembly of the station wagon - 2111. In 1999, the plant began producing hatchbacks.

In the first years of production, the 2110 used a 1.5-liter sixteen-valve engine. At that time, this was the maximum capacity of the plant.

In 2000, the plant introduced new version hatchback - VAZ-2112, 16 valves. Compared to the ordinary eight-valve version, the car had more power and dynamism. The model immediately captivated car enthusiasts; its appearance was sporty.

Options

The car was produced and is offered in “Lux” and “Norma” trim levels. The “Norma” differs from the luxury version only in that there was no trip computer, fog lights, a set of alloy wheels, headlight cleaning system.

"Norma" is equipped with electric windows for all four windows, central locking, drive for remote trunk opening, steering column with height adjustment, immobilizer.

What’s most interesting is that none of the trim levels (no matter how expensive they are) have air conditioning. By today's standards, this is quite a big disadvantage, because of which drivers are increasingly looking towards used foreign cars.

Appearance and body structure

As for the dimensions, the VAZ-2112 (16 valves) decreased in length by 93 mm. This change took place in the rear overhang area. But at the same time, the size of the wheelbase did not transform. The body length was 4170 mm. And the height of 1676 mm and width of 1430 mm remained traditional for the “tenth” family. The topline on this body very smoothly turns into a fairly short rear overhang and a large rear wing. This design allowed the developers to make the car more manageable.

If you compare this hatchback with more classic models VAZ, it is worth noting that the “two-piece” has the best aerodynamic characteristics and modern appearance. The model is very popular among tuning enthusiasts.

The fully galvanized body of the “tens”, which became very popular in its time, is still subject to corrosion. Many owners of new cars did not consider it necessary to carry out anti-corrosion treatment. The bottom very quickly rusted to holes.

Interior and salon

The interior of the VAZ-2112 (16 valves) contains all the best from two brothers. Here the most best characteristics station wagon interior. Backrests rear seats are divided into two parts. Each of them can be folded. This significantly increases the trunk volume. And this is the only advantage. Inside, everything is more modest than in any foreign cars of the same classes and the same years.

The owners say that there is little light both in the cabin and on dashboard. All the panels seem to be perfectly assembled, but something still creaks somewhere. Central tunnel next to hand brake equipped with buttons to control the window lift - it is believed that this is not very convenient to use. There are no such options for rear passengers - even mechanical handles are not provided in the basic configuration.

Another disadvantage, according to the owners of the VAZ-2112 (16 valves), is the complete absence of at least some sound insulation. When driving with music on, you can clearly hear the engine and power steering working.

The big problem is the incredibly cramped pedal block.

From the edge of the brake to the console is just over 10 cm. Many people complain about this very narrow opening. In order to operate the gas pedal, you have to turn your foot sideways. And if you don’t turn it out, then when you press the accelerator pedal, your foot catches the brake. In 2110 this is all right. Maybe the reason here is that the scarf overlay is made more convex? Maybe.

And the front seats are made well. They are additionally equipped with side support. But even here everything is not so clear. Many people complain about inconvenient adjustments. But large people fit perfectly into the cabin and into the driver's seat - this is an advantage, since there is not much space.

Another positive feature is the low height of the trunk shelf. Once the fifth door is opened, nothing interferes with loading.

The car has good visibility. But the mirror in the cabin is not very convenient to use due to the large pillars and the tilt of the glass. Rear passengers also noted excellent characteristics in this plan. But there's little headroom in the back.

Chassis and steering

The main complaint about the chassis is excessive softness. This is all due to the redesigned suspension system. But many drivers lack feedback. And at the same time the car handles perfectly. Turning it a little steering wheel, you will immediately feel the result. In terms of inertia, this hatchback is many times superior to both a sedan and a station wagon. But turning the steering wheel at low speeds is quite difficult. The fault for this lies entirely with the hydraulic booster. It reduces the effort, but this does not make the car more obedient.

The driving characteristics are quite confident. The car is controlled on ice. Of course, there is no ABS here. Brakes with vacuum booster and discs - in front, and drums in the back. They brake - and it's good.

Engine VAZ-2112 (16 valves)

The engineers used something new as a power unit. The unit was not created anew, but on the basis. It retained everything geometric characteristics 83rd, however, it is completely different from it both in power and in other characteristics. Famous people took part in its development car brands. The engine is highly efficient. Among the disadvantages is weak torque at low revs. Owners also write in reviews about a weak belt drive, if the belt will break Timing belt

VAZ-2112 (16 valves) has an engine capacity of 1.5 liters. The power it can produce is 93 hp. With. The torque is 133 Nm at 3300 rpm. Concerning environmental standards, then the motor is designed for Euro-3. There are 2 valves per cylinder. One is for inlet, the second is for outlet.

Design Features

The four-stroke engine of the VAZ-2112 car (16 valve injector) is distinguished by an in-line cylinder and Crankshaft In this unit, two camshafts are common. Liquid based cooling system, closed type. Forced circulation of coolant. Lubrication system combined.

Cylinder block, connecting rods, pistons

The VAZ-2112 engine (16 valves) is equipped with a block cast from high-strength cast iron. At first glance, it seems that it is completely similar to model 21083. But this is not so. The main difference is the 10 mm smaller diameter of the head bolts. Other bosses for injection system sensors and another honing technology.

The connecting rods are made of steel by forging. They are distinguished by their I-section. These same connecting rods can be found on the 2110.

The pistons are steel, hollow, floating. The finger has a diameter of 22 mm. Length - 60.5 mm.

Head VAZ-2112 (16 valves)

This is a completely new cylinder head. It operates two camshafts. It was created with the support of specialists from Porsche. So, two shafts are driven by a gear drive. They are perfectly protected from dirt and dust. Hydraulic pushers were used in the valve drive, and now there is no longer a need for manual

Valve group

They are located in two rows in a V-shape. Their design resembles model 2110, but the diameter of the plates and rods is reduced. Each valve has one spring.

VAZ-21124

Also, the 21124 unit was installed on the “two-wheelers”. Here the volume is 1.6 liters, the power is 89 liters. s., torque - 131 Nm. also represents distributed injection. The engine supports Euro-3 and Euro-4.

This engine is a continuation of the 2112 line. It was possible to increase the volume using crankshaft with a larger crank radius for the same cylinder diameter. The cylinder block here also has an increased height.

Here they were able to solve the problem of valve bending, and the characteristics are at a sports level.

Ignition system

An electronic module is used as the heart of the system. Car owners write a lot about how problematic it is. You should select candles for it very carefully.

The VAZ-2112 ignition (16 valves) has two coils. One serves to operate the first and fourth cylinders, the second - for the second and third. If there are problems in the module, the spark disappears in pairs. The system itself is not maintained or repaired. Its control is entirely given to the controller.

There are several sensors in the system. This is a crankshaft position sensor that sends a signal to the ECU, and then the “electronic intelligence” calculates how to operate the coils. In the formation of the mixture and ignition, the familiar mass air flow sensor, coolant sensor, and knock sensor, which are familiar to many, work. Other VAZ-2112 sensors (16 valves) work the same way. For example, oxygen sensor, exhaust gases.

Typical engine faults

Many car enthusiasts who own " iron horse"with the 2112 engine, they complained about valve deformation when the timing belt broke. This typical fault. The repair is simple. You just need to change the pistons to those on 21124. The problem is solved there, but the price for this will be a decrease in power. If you do not want to lose in this indicator, you need to constantly monitor the belt. Listen to the sounds. First the rollers squeak, then rustle.

In addition, the engine can triple. How to deal with this unpleasant phenomenon? Check the compression level, ignition module, wires. If the speed fluctuates, then you can suspect the throttle valve, crankshaft position sensors, mass air flow sensor.

Another malfunction is noted. It may occur on idle speed and on the go. The engine sometimes stalls when changing gears. Clean the throttle body or throttle sensor.

If the unit does not start at all, check the starter and battery.

The ignition or power system may also be malfunctioning.

With proper care of this engine, the VAZ-2112 (16 valves) will not need repairs. Just follow the manufacturer's instructions and perform regular maintenance. All instructions about basic operations will not cause difficulties.

Prices

At the very beginning, they asked for more for this hatchback than for other models. It was considered quite expensive. This may be due to the power windows and lock. However, a little later prices dropped, and configurations and equipment became richer.

Today, the average price for a VAZ-2112 car (16 valves) is from 90 to 250 thousand rubles, depending on the configuration, tuning, and engine. The car is suitable for various changes, so owners modify it.

According to user reviews, the most optimal cost is about 150 thousand rubles. Since at this level it is not rubbish that is offered.

So, we found out what technical characteristics, price, reviews and configurations the VAZ-2112 car has. Happy shopping!

Many owners of a VAZ 2110 with a 16-valve engine encountered the fact that the engine began to misfire. This effect can occur under different circumstances: cold or hot, or constant mode. Why does the VAZ 2110 engine have problems with the 16-valve injector, and what causes of the malfunction will we examine in this article.

Causes of malfunction

A VAZ class engine can triple due to the lack of one component that promotes combustion fuel mixture- fuel, air or spark. If one of the nodes that is responsible for supplying these elements fails, the engine may jerk, “sneeze,” stall, or start and then stop.

Of course, many car enthusiasts recommend contacting experienced car mechanics, but for the most part, every motorist tries to find out the cause and fix it on their own. So, what could be the reasons for the tripling effect:

• Poor quality fuel.
• Clogged fuel supply system.
• Air does not enter the right amount into the combustion chamber.
• No spark.

Engine diagnostics

Before you start tinkering with the hardware, it’s worth turning to the car’s software and understanding whether the reason may lie in the failure of one of the power unit’s sensors or in a so-called software failure.

So, in order to gain access to the car’s software, the motorist will need some equipment and materials. First, you should find out which engine control unit is installed on the vehicle. To do this, you need to look at the service documentation or decipher the body number.

The second option is not available to everyone, and therefore it is worth following the path of the slightest resistance. For 16-valve power unit VAZ 2110 can be installed with the following types of electronic engine control units:

• January 4/4.1.
• Bosch M1/5/4 (N).
• January 5.1.X.
• January 5.1.Х New
• Bosch MP7.0H.
• VS 5.1.
• Bosch MM7.9.7.
• Bosch 7.9.7+.
• January 7.2.
• January 7.2 New.

Depending on which ECU is installed on the car, it is worth choosing software for diagnostics and repairs software. Also, in the process you cannot do without a USB data cable, which is called OBD II. Well, to perform direct diagnostics and guide the process - a laptop computer or tablet.

Let's proceed directly to the process of diagnostics and troubleshooting. We install the appropriate program on the tablet, which will not only allow it to synchronize with the ECU, but will also make it possible to carry out full diagnostics.

After installing the software, connect the cable to the tablet and control unit. The program should automatically recognize the equipment and synchronize. Then, we launch the diagnostic program and wait for the results.

By analyzing the data obtained, you can understand what the condition of the equipment is and whether there are problems. Typically, diagnostics show failed sensors that need to be replaced.

After replacement, it is worth clearing the accumulated errors and trying to see if the engine operation has changed. If this does not happen and the cause remains, then you should go directly to looking for the causes in the hardware.

Eliminating tripping

Why does the VAZ 2110 engine fail? Because, computer diagnostics and replacing the damaged elements did not produce results, then it is worth checking the mechanics that caused the malfunction.

Fuel system

Recently, many car owners have begun to complain about the appearance of triple vision, although vehicle almost new. The occurrence of such a malfunction is primarily associated with low-quality fuel, which is sold at gas stations.

Such gasoline negatively affects not only the entire fuel system, but also on the state of the combustion chamber. Thus, due to long-term use of such “slurry,” valves and pistons burn out, and oil scraper rings fall into disrepair.

If it turns out that it was flooded low quality fuel, it is recommended to clean the entire system.

To begin with, it is worth examining the condition fuel pump, or rather the mesh filter placed on it. It is a clogged element that can allow fuel to pass through inappropriately. sufficient quantity. Therefore, it is recommended to replace the element, especially since its cost is low and affordable.

The next element that is worth checking are the injectors. They can become clogged not only due to the use of low-quality fuel, but also wear out during operation. Dirty injectors give lean mixture, which can cause tripping. Cleaning of elements is carried out on a special stand, so for high-quality cleaning it is recommended to contact specialists.

Air supply

Contamination of the air supply system can lead to the engine starting to suffocate and tripping to occur. Thus, it is recommended to investigate the condition air filter, because if it is clogged, it prevents the engine from receiving required quantity oxygen.

The next node, the failure of which can lead to tripling, becomes throttle valve. This element may become clogged or worn out during operation. Thus, jamming of a part will lead to a constant single air flow, which may be too little or too much for operating the motors. Therefore, diagnostics and cleaning of spare parts is periodically necessary.

Spark generator

At this node important role spark plugs are played out and high voltage wires. The malfunction of these two elements is the cause of many problems, such as tripping. Therefore, to eliminate the breakdown, it is necessary to dismantle the elements from the vehicle.

Spark plugs are first checked for cracks and physically visible damage and only then for the presence of a spark. So, black or oily contacts can indicate the condition of the motor.

To eliminate the causes, it is necessary to clean contact group and install the elements in place. If there is no spark or have cracks, then it is worth replacing the damaged spare parts, having first checked the new ones and set the necessary clearances.

High-voltage wires are inspected for insulation breakdowns, and resistance is also measured. Typically, it is recommended to install high-voltage wires made by Tesla on Zhiguli motors, the resistance of which should be about 5 ohms. The measurement is carried out using a conventional multimeter.

Conclusion

Possible causes of tripping on the sixteen-valve VAZ 2110 have been identified, and options for solving the problem have been described. If nothing works, then you should contact a car service; you may have to remove the cylinder head and inspect the condition of the valves and piston group. Maybe the engine needs a major overhaul.

At the turn of the XX-XXI centuries, the plant in Tolyatti produced cars, which later received the common name - “Lada 110”. The next after this family is considered to be the “Priora”, which received many parts from the “ten” and its own, deeply modernized units with different capabilities and sores. As with earlier or later cars, VAZ did not limit itself to one version. The tenth had modifications, one of which was the VAZ 21103. Specifications We will look at this car a little later.

This car did not have climate control, on-board computer and other things included in basic equipment modern car. Nevertheless, it was the first car that looked like a foreign car. The plant still uses this body today, but current machines no longer have digital indices.

Main differences

In addition to bodies, “ten”, and then following models received other innovations. Almost 2110 became the first-born car, like the “penny” in its time. The car received ventilated brakes, galvanized bodywork, a gasoline vapor recovery system, space for air conditioning and other innovations. VAZ 21103, in addition to this, received more powerful heaters, ABS system. It was possible to order air conditioning and power steering.

But besides this, all 103 cars received injection engines from models 2111-2112 (see picture). Installing this system immediately allowed us to save on fuel. Current VAZs already have other sizes, but 21103 is still running, and its owners can easily find information about their car.

Salon and external data

Like the older model, VAZ 21103 received front-wheel drive, sedan body, 4 doors, 5 seats. The car could be chosen in three trim levels - “Standard”, “Norma”, or “Lux”. “Standard” was not much different from the base model and is described above. “Norma” - the middle configuration, received electric windows, metallic colors, headrests in the rear seat and velor upholstery, which, according to many users, turned out to be so successful that there was no need to put covers on the seats. The luxury kit has all the features mid-spec, as well as electric mirrors, fog lights, alloy wheels(14 inches) and on-board computer(!!!). Also among the little things we can note a slightly improved unit between the front seats and heated front seats.

Based on the VAZ 21103, several more customized variants appeared executive class. Limousine 21109 “Consul” and stretch sedan (extended sedan) 21108 “Premier”. Both have a partition between the front and rear seats, typical for cars of this class. Lincoln also has a middle section between the front and rear doors, and the stretch has an extended roof and rear doors, as well as a small window behind them.

We also note that other factories also produced this machine under a VAZ license. This is how armored sedans and even the all-wheel drive 4x4 Lada Tarzan-2 were born. This model also interested tuning studios. About 5 separate tuning kits are produced for it.

Engine parameters

As already written, the injector has become the main difference between the new VAZ 21103. 1.5 16v - characteristics of other engine parameters. Let's decipher them: volume 1.5 liters; 16 valves (versus 8 in the first “ten”); V-shaped pistons.

Additionally, you can indicate that the engine itself has 4 cylinders, 4 valves per cylinder. Note that almost everyone now receives the same piston arrangement. modern cars. In the urban driving cycle you will need 8-9 liters per 100 km. Outside the city, consumption does not exceed 6 liters. Since the car is quite old, the engine is designed to refuel AI-92 (some reviews indicate 95). The gas tank volume is 43 liters, the engine power is 93 hp, which gives acceleration to 100 km in 12.5 seconds. Manual gearbox, 5 steps.

Other technical data

We looked at the interior configurations and engine capabilities of the VAZ 21103 (1.5 16v). The technical characteristics of other options do not require special decoding, so we will simply rewrite them in a few lines. Trunk volume 450 l. Considering that the cover reaches almost to the bumper itself, and it is possible to fold rear seats— both standard and long cargo can be placed here. Ground clearance 160 mm. Width 1700 mm, height 1400 mm, length - 4300. Front disc and rear drum brakes. Front suspension: independent McPherson, rear wheels They are slightly recessed, so the front track is 1410 mm, the rear track is 1380.

Conclusion

The “Ten” and then the VAZ 21103 did not become truly new cars. It is unlikely that this was influenced by the presence of the “VAZ” badge on the radiator grille, nevertheless, this car, on the one hand, wide choose components from previous models, on the other hand, the high cost of original components. Also not very good decision suspension, which is why the car, even with this, is quite high ground clearance The engine cover may catch asphalt.

But despite all these shortcomings, this car became a transition between the old Union cars and the new “foreign cars”. In addition, this is perhaps the only VAZ model on the basis of which several custom Lincolns were assembled.

As a rule, they are changed along with the pistons.

Connecting rods - steel, divided into classes by weight– they are marked with paint or a letter on the lid. On the covers, as well as on the connecting rods, the cylinder number is stamped (it should be on one side of the connecting rod and the cover).

Piston pins

This is what a piston pin looks like.

The piston pin is steel, tubular in section. It is secured from falling out by two retaining spring rings, which are located in the grooves of the piston bosses. Based on their diameter, they can be divided into three different classes: 1 – 21,978-21,982 ; 2 – 21,982-21,986 ; 3 – 21,986-21,990 . The piston class is also stamped on its bottom. The piston and pin must be of the same class.

cylinder head

View of the cylinder head on a dismantled engine.

– made of aluminum alloy, common to all four cylinders, It is centered on the block with two bushings and secured with ten screws. On the top of the cylinder head there are supports, five on each side.

Camshafts

Camshafts and their pulleys

The camshafts are cast, cast iron, five-bearing, each with eight cams. The camshafts are driven by a toothed belt from the crankshaft. Due to increased loads on the timing belt, its width in the VAZ-2112 engine, compared to analogues 2110(11), is increased from 19.0 to 25.4 mm (accordingly, the width is increased toothed pulleys and rollers). That's why the . Under the intake pulley camshaft there is a support roller, under the outlet there is a tension roller.

Valves

These valves are not afraid of bending if there are grooves on the pistons.

The valves are made of steel, while the outlet is made of heat-resistant steel with a directional chamfer, and the inlet area is larger than the outlet. If we compare in size, they are smaller than the analogues of the “tenth” model. They are arranged in two rows in a V-shape. They are driven by cams using hydraulic pushers, which in turn are very sensitive to the purity of the oil and its quality. And in the presence of mechanical impurities it is possible premature exit

failure of these elements, which will be accompanied by increased noise during operation of the hydraulic pushers. How to replace these elements is described in detail in this article.

Lubrication system The VAZ-2112 engine is lubricated using a combined method. Using pressure, the root and connecting rod bearings , camshaft and hydraulic pushers. By spraying oil is supplied to the cylinder walls from them to piston rings

and fingers, at the bottom of the pistons, to the camshaft cam-pushrod pair and valve stems. The remaining components are lubricated by gravity.

Oil pump

New oil pump. Oil pump – equipped with internal gears and pressure reducing valve – installed on the front wall of the cylinder block. The oil receiver is bolted to the second main bearing cover and the pump housing.

Oil filter

– is a full-flow, non-separable filter. The crankcase ventilation system itself is closed, forced, by suction of gases through an oil separator located in the cylinder head cover. Injector wiring diagram Today, in practice, many motorists replace the carburetor with an injector, since the latter has a number of advantages. At the same time, the injector installation contains
whole line nuances. In this situation on the VAZ 2110, the injector circuit plays a certain role as a guide that will help you understand all the nuances that will be encountered during installation. Plus everything electrical diagram VAZ 2110 injector 8 valves or 16 is necessary for a practical understanding of the operation of this device, and if there isn’t one, then that’s it

renovation work

• will simply be ineffective.
• The injection system is represented by two components:

fuel distributor;

ignition control system.

The VAZ injection system is designed quite simply and contains practically no nuances specific to understanding. A novice motorist even knows general principle functioning of injection systems.
Elements injection system and their basic functions:

• the fuel regulator is located on the injector, the latter, in turn, is located on the frame to which fuel is supplied using a pump (all the fuel first passes through a specialized filter);
• the fuel pressure should not exceed 300 mPa, therefore, if any excess fuel occurs, it is sent back to the tank using a membrane regulator;
• the bypass valve controls the position of the diaphragm, which in turn is subject to triple pressure: the pressure of the fuel itself, as well as the intake air and the corresponding spring;
• the fuel regulation scheme described above directly depends not only on the current engine load, but also on the throttle position;

• the cylinder is filled with fuel during rotation of the crankshaft, the volume of incoming fuel is determined by the position of the injector (see), which is directly controlled by the controller.

The role of the injector and controller in the overall injector circuit

• the position and opening time of the injector determines the volume of fuel that enters the cylinders;
• special sensors are installed on the engine that transmit relevant information to the controller;
• The controller, based on the information received from the engine, sends electrical impulse a certain length, which determines the duration of opening of the nozzles;
• when starting the engine, the controller is in asynchronous operating mode until the engine itself reaches 400 revolutions in one minute;

• injectors may temporarily not function in the event of braking or if the engine is in purge mode;
• if the engine operates in mode increased load, then the air information transmits the corresponding electrical impulse to the controller, which in turn sends the corresponding signal to the injectors taking into account the current speed of the car;
• Thus, in the injector circuit, the controller is a regulating element, and the injectors are an executive element.

The role of the electronic control unit in the overall injector circuit

From a practical point of view, the block electronic control consists of several high-tech components: ROM - memory devices, PROM - dynamic memory devices, RAM - regulatory memory (all of the above elements function only if there is voltage available).

Note. The electronic unit The control unit is actually a microprocessor, so even an experienced motorist is simply not able to fix it, since specialized knowledge from the relevant higher school is required.

• all engine parameters, together with the microprocessor operating program, are stored in ROM;
• RAM is RAM, which is a temporary source of information storage, and each new start of the microprocessor leads to complete clearing of intermediate information;

• all information coming from the sensors to the controller is not only analyzed, but also stored; at the same time, the controller itself carries out diagnostics of information sensors from time to time;
• Ignition and injectors are the main functional elements of the injection system, subordinate to the controller.

Note. Located on the dashboard signal light“CHECK ENGINE”, if it lights up, it means that the controller is in a faulty state or some kind of malfunction has occurred in its operation.

General diagram of the injector operation

So:

• there is a so-called group of information sensors, which is carried out exclusively by data collection;
• all information goes to the controller, which is the analytical center of the injection system;
• depending on a number of factors, the controller sends an electrical pulse of a certain length directly to the nozzles themselves, which open for a strictly specified time period;
• The efficiency of the cylinders and, consequently, the engine itself depends on how much fuel and air are supplied from the injectors.

Note. A certain amount of air corresponds to a certain amount of fuel (if this ratio is violated, then the engine power will correspondingly decrease significantly).

The price of an injector (see) is a flexible concept and depends on a number of components. However, the cost of fixing an injector problem at a car service center is very significant.
The DIY repair instructions allow you to fix the problem, but you need to have a good understanding of the injector circuit. Photos and videos - materials in this matter will become the most valuable practical assistant.
