Renault owners are quite familiar with the H4M engine. The power unit is a direct descendant of Nissan's HR16DE. By and large, these are the same engines, from different manufacturers. The motor was installed on vehicles produced by Renault and AvtoVAZ. The engine itself comes from France, as it was developed by French engineers, but has taken root quite well in Japan.

Characteristics

The H4M engine is a modified K4M powerplant. This was an evolutionary solution to a not entirely reliable and power-hungry power unit. Renault designers were given the task of making an unpretentious engine that is ideal for any region of use, and can also be installed on cars different classes and appointments.

Unlike its predecessor, the gas distribution system uses a chain instead of a belt, but a significant drawback is the absence of hydraulic compensators. It is because of this that every owner must adjust the valves every 80,000 km. A large adjustment interval is achieved thanks to the presence of pushers.

Changes have also been made camshafts. Thanks to this, it became possible to install two injectors on each cylinder. This significantly reduced consumption, increased environmental standard.

The oil filter is used by Nissan and has catalog numbers- 152085758R and 15208-65F0A. You can also select according to original articles sufficient quantity analogues

Maintenance scheme:

1. TO-0. It is carried out from 1500 to 2000 km. Regular factory oil changes, all filters are also changed.
2. TO-1. This is done after 12-15 thousand kilometers. Comprehensive service Total power unit. From replacing consumables and oil to full diagnostics engine condition.
3. TO-2. Replacement lubricating fluid, oil and fuel filter elements. Scanning for ECU errors. Troubleshoot if necessary.
4. TO-3. In addition to standard operations, brake system diagnostics are added.

Subsequent maintenance is carried out by analogy with TO1 - TO3. As practice shows, most motorists undergo maintenance at dealer stations only during the warranty period. At the expiration of warranty service Car enthusiasts begin the maintenance process on their own. This allows you to save up to 2/3 of the monetary equivalent of the cost of operations in a car service center.

Malfunctions

The automaker claims that the engine did not show any particular shortcomings during testing, but car enthusiasts have their own opinion on this matter. Yes, they were found design flaws, which are inherent in all H4M motors. Troubleshooting is usually done by car enthusiasts on their own. Let's consider the main ones, as well as ways to eliminate them:

1. Vibration. It can be heard quite clearly when starting the engine, as well as at idle speed. This means that the right motor mount needs to be replaced.
2. Roar and evil sound. In this case, it is necessary to inspect exhaust system. Often this sound begins to appear when the muffler rings burn out or there are breakdowns.
3. The H4M engine stalls. The engine can stall for several reasons - faulty sensors, errors in the engine control unit, dirty throttle or an ignition problem. The initial sign of this problem may be periodic tripling.
4. Whistle under the hood. Since there is no timing belt, the reason is the alternator belt, which has stretched and is slipping. Replacing the element will help solve the problem.

Tuning

Refinement of the H4M engine is divided into two types: chip tuning and turbine installation. Firmware for power will help add 5-10% of the main power, but at the same time it will proportionally increase fuel consumption. This is worth considering when making a decision. You can perform chip tuning using a K-line cable, software and availability of time. But, in most cases, it is recommended to contact special car service, where specialists will select and configure the optimal configuration for the motor.

The second option is to install a turbine. The cheapest option is a VW turbine labeled K03. It comes with an intercooler and piping. In this case, it is necessary to remake (digest) the entire exhaust system and manifold. To save money, you don’t have to change the connecting rod and piston group, but you can’t inflate more than 0.5 bar. All this gives 150 hp, which is more than enough for urban and suburban use.

If you want to increase power to 180-200 hp, you will have to replace the camshaft and install lightweight pistons and valves. In this case, it will not be possible to do without installing a more powerful turbine and flashing the engine control unit with special software.

But don’t get too carried away with tuning and adding power. This can lead to the motor reducing its service life by 1/3. Therefore, it is recommended to contact professionals who will make calculations and select best option improvements.

H4M engine: reviews

Most motor owners were satisfied with the use power plant. The H4M engine turned out to be unpretentious in repair and maintenance. Most owners note that they carry out maintenance and restoration and repair operations on their own, without resorting to the help of a car service.

Conclusion

Renault H4M engine co-production Renault Nissan is a high-quality power unit that has increased specifications, economical and meets all standards. Maintenance is quite simple and typical, every 15,000 km. But it is recommended to reduce the service interval to 12,000 km, which will increase the service life.

Engine malfunctions and repairs Qashqai / Tiida / Beetle / Note HR16DE

The Renault-Nissan H4M-HR16DE engine is an evolution of the Renault engine, replacing the QG16DE in the Nissan line. The engine is not bad, it is not demanding on gasoline, with the recommended 95, you can use 92. The timing system uses a chain, here it is quite reliable and its early stretching will not bother you. There is a variable valve timing system, the phase shifter is installed on the intake shaft, an electronic throttle valve, but the valve clearances on the HR16DE need to be adjusted; there are no hydraulic compensators. The gaps are adjusted by selecting a pusher, approximately once every 80-100 thousand km. Engine noise and knocking are the main signs of an imminent trip for adjustment.
This engine has been modernized, the camshafts have been changed, two injectors are now installed on each cylinder, fuel economy has increased, power has increased slightly, and idle speed, the engine began to comply with Euro 5 requirements and other, less significant, transformations.
Let's talk about malfunctions and ways to repair them on the HR16DE-Н4М.
1. Engine whistle. As with many Nissan engines, this whistle is nothing more than the sound of the alternator belt; the problem is solved by tightening it, but if there is nowhere to pull, then replacing the belt.
2. The engine stalls. Here the problem is in the ignition unit relay; Nissan recalled a batch of cars for this fault. With this malfunction, you risk stalling in the middle of the road and it is not a fact that you will start. The problem is solved by ordering a new ignition unit relay.
3. Burnout of the ring exhaust pipe. Symptoms: at medium speeds when accelerating, a more angry sound is heard. Change the gasket and drive further in silence.
4. Engine vibration. Typically, this is a symptom of the impending demise of the right HR16DE-H4M engine mount. Replacement will solve all issues.
In addition, the HR16DE-H4M engine does not start well and stalls severe frost(from -15 C), you can change the spark plugs, start with gas, this will improve the situation a little, but in general, this is such an unpleasant feature of the engine. On CVT variator Shocks are felt when switching.
To summarize, the HR16DE-H4M is a completely ordinary engine in its class, no worse, but not better than analogues, some smaller version . Is it worth buying a car with such an engine? If you are a calm person and racing is not for you, of course it’s worth it, otherwise look at more powerful engines.

Engine tuning Tiida/Beetle/Qashqai/Nout HR16DE-H4M

Chip tuning. Atmo

The most popular and folk way increase the power is a sports firmware. Chip tuning HR16DE will not fundamentally change anything, the increase (if any) will be ~5%, no matter how happy the owners are after calibration, this looks like nothing more than self-hypnosis. For a more significant increase, look for an exhaust manifold 4-2-1 and straight-through exhaust, on a 2-inch pipe, cold air intake and firmware. This will not give a big increase, but about 125 hp. It will be possible to remove it, in order to move on, you need to set the boost.

Turbine on HR16DE/HR16DET

There are projects with a small turbine on a standard piston one; this is the cheapest turbocharging option. A VW K03 turbine with an intercooler and piping is purchased, a manifold is welded for it, standard injectors, a direct-flow exhaust on a 2″ pipe, and all this needs to be configured. There is no point in blowing more than 0.5 bar into a standard ShPG, otherwise prepare money for repairs. The maximum that can be squeezed out from this configuration is about 160 hp. For further movement, you need to expand the engine for a more powerful turbine, injectors with a capacity of 440cc, powerful fuel pump and piston with a puddle, under coolant ~8. Power, depending on the turbine, will be 200 hp or more.

The N4M power unit is a representative of the French automobile industry from Renault. These engines were installed not only on cars produced at the Renault plant, but also on AvtoVAZ. The power unit is considered quite reliable and structurally simple.

Specifications

The N4M engine is a direct successor to the famous K4M engine. A fairly simple design makes it easy to maintain and repair the motor. The engine is not picky about fuel; it can be filled with both 92nd and 95th gasoline.

With gas, everything will be more difficult, since it is not recommended to install methane-based gas equipment, but the engine should be calm about propane.

Let's consider the main technical characteristics of the power unit:

Applicability

N4M has received quite a wide range of applications, especially in japanese cars produced by Nissan (part of the Renault group). So, let's look at which vehicles the power unit was mounted on: Nissan Note, Nissan Tiida, Nissan Qashqai, Nissan Sentra, Nissan Juke, Lada Vesta, Lada X-Ray, Renault Logan, Nissan Micra, Nissan Wingroad, Nissan Cube, Nissan Bluebird Sylphy, Nissan Latio, Nissan Grand Livina, Nissan Versa and Nissan NV200.

Service

The power unit is serviced every 15,000 km. Experienced motorists recommend reducing the service interval to 10,000 km. This will preserve the properties of the engine longer and extend its service life.

The engine oil capacity is 4.3 liters, but only 4 liters are required to change. Recommended replacement oils are marked as follows: 0W-30, 0W-40, 5W-30, 5W-40, 10W-30, 10W-40, 10W-60 and 15W-40.

Maintenance is carried out according to the following scheme:

TO-1: Oil change, replacement oil filter. Carry out after the first 1000-1500 km. This stage is also called the break-in stage, since the engine elements are grinding in.

TO-2: Second Maintenance carried out after 10,000 km. So, they change again engine oil and filter, as well as an air filter element. At this stage, the pressure on the engine is also measured and the valves are adjusted.

TO-3: At this stage, which is performed after 20,000 km, the standard procedure for changing the oil is carried out, replacing fuel filter, as well as diagnostics of all engine systems.

TO-4: The fourth maintenance is perhaps the simplest. After 30,000 km, only the oil and oil filter element are changed.

TO-5: The fifth maintenance is like a second wind for the engine. This time the timing drive, oil and filter, filter elements are changed fuel system and air filter. Also, injectors and spark plugs are checked. Special attention It is worth paying attention to computer diagnostics.

Malfunctions and repairs

The N4M engine is quite reliable, but it also has a number of problems that cannot be avoided. Since 2 injectors are installed on each cylinder, it is quite difficult to diagnose the condition of the injection system. So, in order to determine the performance of the injectors, they must be removed from the engine and checked on a special stand.

Let's consider the main malfunctions that arise during engine operation:

1. Whistle under the hood. In this contest it is worth inspecting the alternator belt, which is most likely stretched.
2. The engine stalls. There may be several reasons for this - faulty sensors or spark plugs, dirty throttle or air filter, or there is a problem in the on-board computer.
3. Evil sound. This means that the exhaust pipe rings have burnt out.
4. Vibration. The right power unit cushion has failed.

As you can see, the motor does not have any global problems, and therefore can be considered a reliable power unit.

Conclusion

N4M engines are quite reliable and have a long service life. The power unit must be serviced every 15,000 km, but experienced motorists It is recommended to carry out it after 10,000 km. There are some faults, but they are minor.

The H4M K-1 engine (HR16DE) originally belonged to Nissan, but layered policies and combinations of technologies allowed this engine to broaden its horizons. Until recently, this engine was installed on Renault Fluence, Scenic, Nissan Note, Tiida, Qashqai and many other models.
The history of the motor begins in 2006, that’s when it was put into production. It is worth noting that on different models, this motor produces different power: somewhere 114 hp, somewhere 118 hp, on the Xray, as well as on the Vesta, the power is 110 hp.

On this moment The motor is assembled in Russia.

• Inlet phase shifter
• The engine resource is about 250 thousand km.
• 2 injectors per cylinder are installed

Tuning the H4M engine

Civil tuning for this engine is limited to the release of 4-2-1 or 4-1- without catalysts and other firmware. The maximum you can get from such an engine is around 125 horsepower. In this regard, in my opinion, the 21129 engine has much greater prospects due to the presence of tuning hardware: from pistons and camshafts to the turbo).

Nissan engine malfunctions:

At the moment it is difficult to say anything about this engine in the VAZ version, because sales began relatively recently and the mileage of these engines is minimal. But the long history of the life of these engines on other cars can tell us something:

• Alternator belt whistle (belt tightening or replacement)
• engine knocking during operation (most likely it’s time to adjust the valve clearance)
• hard to start in cold weather

Honda H23 engine malfunctions and repairs

Together with the 2.2 liter H22A, its stroker version with a displacement of 2.3 liters appeared - H23A. This engine is equipped with the samealuminum cylinder block with a height of 219.5 mm, with FRM walls. But there are differences between the H23A and the H22A, and they lie in the crankshaft with a piston stroke of 95 mm, in the pistons with a compression height of 30.5 mm, in the shortened connecting rods of 141.5 mm. By squeezing this into the cylinder block, the engineers achieved a displacement of 2.3 liters.
The H23A head has two camshafts and 4 valves per cylinder, but it does not have variable valve timing and VTEC valve lift. On JDM versions diameter intake valves 35 mm, exhaust 30 mm, the rest 34/29 mm.
The H23A engine needs valve adjustment every 40-50 thousand km. Valve clearances for cold: intake 0.07-0.11 mm, exhaust 0.15-0.19 mm.
These engines were equipped with injectors with a capacity of 240 cc. The diameter of the throttle valve is the same as on the H22A and is 60 mm.

Together with the H-series, Honda produced a technically similar F series of engines, which included models such as F18, F20, F22 and F23.
The H23A engine was produced until 2002, and then was replaced by the K24A.

Honda H23 engine modifications

1. H23A - There are two versions of JDM H23A:
- H23A Black top - standard JDM version with a power of 165 hp. at 5800 rpm. Installed on Ascot Innova.
- H23A Blue top is the top version of this engine with VTEC. Its difference is the PDE head, which is close to the H22A Euro R, the compression ratio is increased to 10.6, the throttle body is like on the Euro R, the injectors are 295 cc. H23A VTEC is found on Accord Wagon SiR and AWD. Develops power of 190 hp. at 6800 rpm and 200 hp. at 6800 rpm, torque 221 Nm at 5300 rpm in both cases.
2. H23A1 Black top - version for North America. Power 162 hp at 5800 rpm, torque 212 Nm at 4500 rpm. Installed on Prelude 4.
3. H23A2 Black top - European version H23A1 for Prelude 4.
4. H23A3 Black top - European version of H23A2 for Accord and Rover 623.

Problems and disadvantages of Honda H23A engines

The main problems of this engine are the same as those of its 2.2 liter brother. you can find out about them all.

Honda H23A engine tuning

Atmospheric. Turbo

The simple H23A tuning includes an H22A Euro R intake, 4-2-1 manifold and 63mm exhaust. This will add about 20 hp. By adding Skunk2 Pro1 camshafts, valve springs and split gears, you'll get about 10 more hp. By porting the cylinder head and installing Skunk2 Pro2 camshafts, you will pass the 250 hp mark. Invest more more money This engine doesn't make sense - it's cheaper to buy a faster car.
It is possible to assemble a turbo analogue of the H22A, as described, but the price will be very high.
