Faults and engine repair Teana / Qashqai / X-Trail / Megan / Fluence MR20DE / M4R

The Nissan MR20DE engine came to replace it, it is a longer-stroke and high-torque engine with a timing chain. Used by Nissan popular cars, Teana, Qashqai, X-Trail, and is also used by the friendly automaker Renault on their Megans, Fluences, Clio 3 and many other popular cars. The resource of the MR20DE / M4R engine is high, mileage over 300 thousand km is not at all uncommon.

The motor is equipped with a system for changing the valve timing on the intake shaft, but there are no hydraulic lifters on the MR20DE / M4R, having heard the engine knock, most likely, you need to go to adjust the valves. They are regulated by washers and these works are performed as needed. Otherwise, the motor is simple and does not have any new and outstanding technologies. Let's talk about malfunctions and their repair:
1. high consumption oils. A frequent problem and a sign of the formation of soot in the cylinder, the death of oil scraper rings, etc. The problem is solved by a trip to the service, followed by diagnostics and repair.
2. Stretching the timing chain. Signs: uneven idling, dips, loss of power. The solution is simple, change the chain and everything is back to normal.
3. Engine whistle. Squealing in the cold haunts, annoys and frightens many, in fact, the alternator belt whistles. The belt can be tightened or replaced if severe wear is noticeable.
4. MR20DE/M4R speed floats. The problem of revolutions has already tortured everyone, but is solved by ordinary cleaning of the throttle.

Among other malfunctions and features, it is worth highlighting the problem with cracking the cylinder head, when replacing candles it is important not to twist them, otherwise cracks in the thread will go, the motor will start to triple and the triple will be progressive, gurgling will appear in the expansion tank, opening the hood, you will see a lot of antifreeze in candle well, usually in the first. These troubles are eliminated by replacing the cylinder head, the price of events is high ... To avoid such happiness, you need to change the candles on a cold engine and pull with a torque wrench (15-20Hm).

Summing up, the MR20DE / M4R is quite an ordinary motor, with its advantages and disadvantages, with careful and quiet operation, it will serve you, faithfully, for more than one hundred thousand km. There is also a smaller version of it, with a working volume of 1.6 liters - .

Engine Tuning Teana/Qashqai/X-Trail/Megan/Fluence MR20DE/M4R

Chip tuning. Atmo

This motor is probably worst choice for tuning, hardware for the engine cannot be found either in the CIS or abroad, so forget about the sports intake, exhaust, shafts and other joys. As a consolation, you can go to the tuners for firmware, but an increase of as much as 5hp. it is simply impossible to feel.

Turbine/Compressor on MR20DE/MR20DET

If putting a turbine on the QR20DE engine was expensive and not very rational, then turbocharging the MR20DE / M4R is the lot of the most ardent fans of Qashqai / X-Trail and other cars with this engine. There are no turbo kits for this engine and you will have to do everything from scratch, buy a turbine with an intercooler, weld a manifold for it, collect piping, look for a reinforced forged SHPG, install a powerful fuel pump, injectors with a capacity of 440cc, exhaust on a 2.5 inch pipe, and a number of others little things and everything is properly calibrated. Similar projects exist and produce over 300 hp, but this is more suitable for ardent fans than the common man.
As for the compressor, it’s simpler here, we order a supercharger, an intercooler, put it on standard engine, we will change the exhaust to a 2.5″ pipe, 440cc nozzles and blow 0.5-0.7 bar with an intercooler, up to 200 hp the motor will last, not for long though)). Next, we change the BHPG to a forged one with a reduced compression ratio, a more powerful fuel pump and install a more powerful compressor. This approach is simpler, cheaper, as a result, the return is lower, then it's up to you.

Nissan Qashqai - modern compact crossover With high rates dynamism and power, which has taken a leading position among cars of this class in domestic market. The manufacturer offers a choice of Nissan Qashqai engine in three versions for the restyled generation, each of which has its own characteristics.

Features of second generation units

The second generation line consists of engines such as turbocharged engine 1.2 liters, two-liter powerful 1.6 liters, which runs on diesel fuel. Technical, as well as the design parameters of the mechanisms, vary significantly. But each of them has its own specific problems, which are confirmed by the feedback from the owners operating a particular engine model.

At Nissan Qashqai, 1.2 and 2.0 engines are offered both on mechanics and in a complete set with a variator. The Qashqai 1.6 liter engine is equipped with a variator only.

All of them are equipped with a timing chain mechanism. If you choose with which type (chain or belt) it is better to purchase a motor, then it is worth noting that the chain has a better service life, which means that you will have to contact the service station more often with a belt.

Atmospheric engine 2.0 l

Qashqai 2.0 atmospheric engine - proven and functional unit whose reliability has been proven over the years. Its design is aluminum block of 4 cylinders with 16 valves. They put on the motor, which ensures a long engine life and high reliability mechanism. However, the engine does not have hydraulic valve lifters, which is its minus. The power system on Qashqai with a 2.0 motor is represented by injector injection with variable valve timing. Such a system provides a high degree of efficiency and at the same time .

The variator features more economical consumption gasoline while mechanical box gear is not as economical, but more practical.

1.2 liter engine

The 1.2 liter turbocharged engine standing on the Nissan Qashqai has high performance indicators, optimal power and excellent torque with minimal gas mileage. The fuel injection system on the engine is of the direct type. However, it is small, and it is also quite demanding on the quality of the fuel used. Mounted on the engine with a chain. The turbocharged engine is also available with a CVT or manual transmission.

A two-liter and 1.2 turbo engine use gasoline, and a car with a 1.6-liter engine runs on diesel fuel. At the same time, no matter what type of fuel the crossover uses, its consumption is quite economical.

Engine 1.6 liters

The Nissan Qashqai 1.6 liter engine is no less interesting than the first two units presented. It provides the best fuel economy and allows the minimum percentage of environmental pollution during operation.

Comparative description of units with technical side tabulated:

Asking the question which engine should be preferred among the units offered by the manufacturer, it should be noted that they are all reliable and do not require frequent maintenance in warranty period operation.

The engine for the Nissan Qashqai 2.0 liter has good specifications and reviews. At the same time, a car with a Qashqai 1.2 liter engine is distinguished by fuel economy. And the 1.6-liter engine offers a car with the maximum torque among the proposed options, even when the speed is not at its peak. high level. It is impossible to put an unambiguous equal sign between the varieties of units, since each has its own problems in operation and undeniable advantages in which it is difficult for the motor to compete. But it is noteworthy that even extreme temperatures do not affect the operation of each of the engines when using quality lubricants.

Conclusion

At nissan cars Qashqai with engines of all types is a reliable and practical system of power units, and therefore none of the motors can be singled out as the best. With what parameters to choose a car, you can decide based on its intended operating conditions. The correct and deliberate decision would be to consult a good specialist before making a purchase.

Nissan Qashqai compact crossover, which is very popular. It is released in 2006. Nissan occupies a position between the Nissan X-Trail/Nissan Murano and Nissan Juke. Qashqai was created to compete with Suzuki Grand Vitara, Kia Sportage, Toyota RAV4, Mitsubishi Outlander/ASX, VW Tiguan, Hyundai ix35. Nissan Qashqai engines are quite simple. On the first generation, gasoline HR16DE and MR20DE were installed, and diesel engines K9K, M9R and R9M. The next version was equipped with the old MR20DE, the new turbocharged HR12DDT 1.2 liters, MR16DDT 1.6 liters. There are diesel engines such as Renault K9K and M9R. As part of the article, we will consider the main disadvantages of Qashqai engines, the oil used, the frequency of its replacement, and engine resources. In addition, the possibility of tuning will be considered.

ENGINE TEAN / QASHQAI / X-TRAIL / MEGAN / FLUENCE MR20DE/M4R

The Nissan MR20DE engine has become the replacement for the QR20DE, this engine has a longer stroke and more power, as well as timing on the chain. Nissan puts such an engine on its main models, such as Teana, Qashqai, X-Trail. The engine is also used by a friendly Renault manufacturer, in particular for Megan, Fluence, Clio 3 models. The MR20DE / M4R engine mileage can often exceed 300,000. The engine has a system for changing the valve timing on the intake shaft, there are no hydraulic compensators. Valves regulate washers. In general, the engine is simple and does not have any innovations. Among the malfunctions characteristic of the engine are the following.

Significant oil consumption. Often there is carbon deposits in the cylinder, deaths break oil scraper rings and similar faults. Therefore, timely thorough diagnosis is necessary.
The timing chain is stretched. Symptoms of this malfunction are uneven idle move, dip, power loss. Solved by replacing the chain.
The engine whistles. The reason is the alternator belt. It is solved by replacing it or tightening it. 4. Floating speed MR20DE/M4R. In order to fix this, you need to clean the throttle body.

Cylinder head cracking can also be noted, twisting should be avoided when replacing candles, otherwise the thread will get cracked, the engine will stall and this phenomenon will progress, there will be gurgling sounds in the area expansion tank, under the hood there will be a significant amount of antifreeze that has fallen into the candle well. In this case, you need to replace the cylinder head. To prevent this from happening, it is necessary to replace the spark plugs with a cold engine using torque wrench 5-20 hm. As a result, the MR20DE / M4R is a simple engine that has both pluses and minuses, subject to timely and quality care it will serve its owner well. There is a smaller version of the engine with a volume of 1.6 liters, this is the HR16DE.

TUNING POSSIBILITIES

The engine does not have significant tuning options. There are no suitable elements for this, not only in our country, but also abroad. This means that the option with a sports inlet, outlet, shafts will not work here. Firmware may be the way out, but it gives only a slight increase. An alternative would be to install a turbine. It should be understood that this option is at the same time quite expensive. There are no turbo whales for the engine, which means it will be necessary to purchase a turbine with an intercooler, make an appropriate manifold, assemble piping, search for a reinforced forged SHPG, install a strong fuel pump, injectors with a capacity of over 440cc, exhaust with a 2.5-inch pipe, additional elements and competent tuning . This option will help to achieve 300 hp. You can use a compressor. A supercharger is required, an intercooler is installed on a standard engine, a 2.5 inch pipe is installed instead of an exhaust, the use of 440 cc nozzles and a boost of 0.5-0.7 bar and an intercooler will achieve 200 hp. You can replace the SHPG with a forged one with a reduced compression ratio, use a more powerful gas pump, put a stronger compressor.

The eminent Korean auto brand Hyundai presented a recently upgraded version of the Tucson model, in the name of which the word Sport appeared.

The lion's share of design elements and technical equipment went to the new product from its predecessor. Only the black shade of the roof rails, which were silver in the previous version, catches the eye.

Tucson Sport is implemented on the basis of the Elite modification (maximum), where the client is offered leather upholstery, cruise control, multimedia system with a large monitor, as well as LED optics and a blind spot monitoring system.

As for power equipment, the updated version offers a forced two-liter turbodiesel (CRDi) with 204 hp, working in conjunction with an eight-speed automatic transmission.

also in motor line there is a gasoline 1.4-liter turbo engine pumped up to 204 hp. Here, a seven-speed robotic box is used as a transmission. The model under discussion is equipped with a front-wheel drive system.

Alas, Tucson Sport is not yet planned to be delivered to Russia. Do you think that local fans of the auto brand would appreciate the sports improvements?

According to official figures, BMW designers have doubled the production of high-voltage batteries at the plant, located in Spartanburg.

The batteries produced will be used for the new X5 and X3 models. It was possible to achieve production growth due to the opening of a new line for the assembly of units, as well as by increasing the production area.

Investment in expansion production capacity amounted to 631,572,000 rubles (in terms of our money). Doubling the number of electric batteries produced will help meet market demand.

As a result of all the improvements, the car turned into a full-fledged camper and received additional "sports" details. So for the exterior of the van, a sports body kit and extended wheel arches were used. If desired, buyers can opt for a lowered suspension kit and a new exhaust system.

The interior of the van has also received a fair amount of changes. In particular, new wheel, carbon fiber trim, two-tone seats with blue upgraded seat belts.

Under the hood of the car is a two-liter turbodiesel engine with a capacity of 170 horsepower. According to preliminary data, the cost of the van will be 6.04 million rubles.

The advantage of the van is that it can be used as a full-fledged motor home when traveling.
