Is Infiniti s domestic Q50L gearbox really frustrated?

The root cause of transmission failure is high temperatures.

Too high temperature in the gearbox will be afraid of damaging the quality and friction performance of the gearbox oil, aggravating friction and wear, and at the same time, sludge will also be generated in the gearbox, resulting in valve body and management blockage, unable to achieve sequential adjustment of oil pressure, resulting in gearbox failure.

There is a theorem: at a normal operating temperature of 80 degrees Celsius, the lifetime of the ATF is halved for every 10 degrees Celsius temperature rise. For example, at 90 degrees Celsius, the service life of an ATF is reduced to 75,000 km.

At 100 degrees Celsius (a temperature often seen by many gearboxes), the service life is only about 35,000 kilometers. At 120 degrees Celsius, it is 15,000 kilometers. At another 10 degrees Celsius, the service life is only 7,500 kilometers.

This can be solved with the Marty ATF and the Matti TA, which quickly cleans the dirt and sludge inside the gearbox. When adding mati ta when changing the oil, matita can penetrate into the metal surface to form a new organometallic film layer, avoid rough and sharp friction, and make the metal surface moving in opposite directions without wear in sliding.

Mattita also contains highly effective antioxidants to prevent oxidation and delay the resulting oil aging process, and can be combined with transmission oil additives to form a strong combination, the outstanding effect is to protect the oil while reducing wear and improving the load capacity, effectively reducing the temperature in the transmission by about 30%, extending the oil change interval by 3-5 times.

The Infiniti Q50L is based on the same platform as the Mercedes-Benz C-Class. Nissan Renault and Mercedes-Benz are now partners, and many technologies such as engine gearboxes are common, Infiniti Q50L and Mercedes-Benz C-Class are the best examples, and the transmission of Infiniti Q50L is the 7-speed gearbox on Mercedes-Benz C-Class, the chassis is the same, but the Q50L is longer, and the engine is the same.

18 models of Infiniti Q50LGearboxThe model number is RE7R01A. The gearbox has excellent smoothness and consistency in shifting, and the bumps in the drive are very slight. It can be said that the driving comfort of the Infiniti Q50L is very high.

Turbocharged engine, the car engine has a maximum output of 155kW and a maximum torque. It accelerates to 100 km/h in about a second, and the top speed can reach 235 km/h. This dynamic performance is very strong.

Infiniti Q50L gearbox maintenanceMaster automatic transmission.

The oil change cycle, the internal control mechanism of the automatic transmission is very precise, and the clearance is matched.

It is small, so most manufacturers recommend that the oil change interval of automatic transmissions is generally two years or 4-60,000 kilometers. During normal use, the operating temperature of transmission fluid is generally 120 degrees Celsius.

The left and right lead is simple, so the oil quality is very high, and it must be kept clean, and the transmission oil will produce oil scale after long-term use, which may form sludge.

Summary. Good evening dear.

The origin is different. The Q50L is made by Dongfeng Infiniti, and the Q50 is imported from Japan's Infiniti. Chinese like to be big, so all cars that are easy to sell are basically lengthened.

The engine of the imported version of the imported version of the Q50L will be discontinued as standard, and only the hybrid model will be retained. After all, we must protect our own market, otherwise everyone will definitely only buy Q50

Difference Between Infiniti Q50 and Q50L:

Good evening parents are of different origins. The Q50L is made by Dongfeng Infiniti, and the Q50 is imported from Japan's Infiniti. Chinese like to be big, so all cars that are easy to sell are basically lengthened.

The engine of the imported version of the imported version of the Q50L will be discontinued as standard, and only the hybrid model will be retained. After all, we must protect our own market, otherwise everyone will definitely only buy Q50

One is domestic, one is imported, the domestic one is from the Xiangyang factory, and the imported one is from the Japanese factory, which is from the same production line as the Japanese god car GTR, and the standard is higher than the national standard. The rest is the difference in appearance and size. There is no version of the import now.

The 18 Infiniti Q50L transmission model is RE7R01A. The gearbox has excellent smoothness and consistency in shifting, and the stuttering sensation during driving is very slight. It can be said that the driving comfort of the Infiniti Q50L is very high.

Cylinder turbocharged engine with a maximum output of 155kW and a maximum torque. It accelerates to 100 km/h in about a second, and the top speed can reach 235 km/h. This dynamic performance is very strong.

Infiniti Q50L gearbox maintenanceMaster the oil change cycle of automatic transmission, the internal control mechanism of automatic transmission is very precise, and the clearance is small, so most manufacturers recommend that the oil change cycle of automatic transmission is generally two years or 4-60,000 kilometers. In the process of normal use, the temperature of the working Huai sail pants of the variable speed lead box oil car is generally about 120 degrees Celsius, so the oil quality is very high and must be kept clean.

The quality of the Infiniti Q50L engine is particularly good. Normal use, and maintenance on time, more than ten years of driving, basically no problem. It doesn't have many minor glitches and is very easy to use.

The quality of the engine is certainly stable and generally does not break down. On the whole, there are not many small problems, otherwise it will be on the complaint list.

Mercedes powertrain, good quality, good power.

The noise is on the high side, and there are few faults.

Infiniti Q50L0-100 km hour acceleration time in seconds: 1, for the facelift, the design changes are not drastic reforms, but the 2018 Infiniti Q50L (codename**Q50L) has been adjusted more refined, first of all, the front of the car uses a larger size of the grille, the front face has a stronger sense of impact and tension, and the change in the position of the fog Xun Qing lamp has also strengthened this momentum;

2. In addition, the tail adjustment adopts a new taillight shape, which has a stronger sense of streamlining, and the waistline style that sets off the dynamic is more fitting; The shape of the wheel has undergone a new design, in short, the strength is not very large, but the exquisite effect is still there;

3. The high gear sense of the interior has been improved, the main change comes from the new sports steering wheel design, the shape is exquisite and not as heavy as the old model, and the design of stitching has been added to the dashboard in the car to enhance the texture of the interior, and the gear lever is also applied to the new model, compared with the old and new styles, it will feel that the old design is a bit too casual, and the new shape still makes people have the interest of fiddling;

4. In addition, the backlight of the main book in the dashboard has changed from the original blue to a simple off-white, and the clean and bright style is very comfortable.

Millions of car purchase subsidies.

The Infiniti 18 Q50L gearbox can withstand 243 torque. The gearbox mainly refers to the gearbox of the car, which is divided into two types: manual and automatic. The manual transmission is mainly composed of gears and shafts, and the variable speed torque is generated through different gear combinations, while the automatic transmission AT is composed of a hydraulic torque converter, planetary gears and a hydraulic control system.

The role of the gearboxChange the transmission ratio, expand the range of change of torque and speed of the driving wheel, under the condition that the direction of rotation of the engine remains unchanged, make the car drive backwards, use neutral gear, interrupt the power transmission, take the engine to start, change speed, and facilitate the transmission to shift gears or carry out power output, the transmission is composed of a transmission mechanism and a control mechanism, and when necessary, a power take-off can also be installed.

The function of the transmission is to change the speed and torque from the engine mechanism, Bu Kuan can fix or shift to change the output shaft and input shaft transmission ratio, also known as the gearbox, the transmission is composed of a transmission mechanism and a control mechanism, the main role of the transmission mechanism is to change the value and direction of torque and speed.
