Mercedes-Benz 274 engine has moreReplacement of timing sprocket

1, "There are the following relevant contents: The replacement cycle of the car's engine timing chain is as follows: the timing chain is used normally within 150,000 kilometers, and basically it is checked once when the car has driven 200,000 kilometers.

2. The timing chain is usually replaced every 150,000 kilometers. Compared with the synchronous belt, the timing chain has a longer service life and a low failure rate, but it is maintenance-free for life. During the operation of the engine, there is wear between the timing chain and the sprocket, and it also has a certain service life. But the timing chain is lubricated with lubricating oil.

3. The replacement cycle is about 150,000-200,000 kilometers, depending on the actual use of the car. If the car is well maintained at ordinary times, there will be no engine failure or something like that., you can continue to use it. For example, your car has 110,000 kilometers. You can consider changing the generator belt outside the engine to check whether there is aging.

4. The replacement cycle is about 150,000-200,000 kilometers, depending on the actual use of the car. If the car is well maintained and there is no engine failure, you can continue to use it. For example, if your car has 110,000 kilometers, you can consider changing the generator belt outside the engine to check for aging. Briefly talk about the synchronization belt.

The difference between Mercedes-Benz m274 and Infiniti m274

The Mercedes-Benz M274 engine has one more ternary catalyst than Finiti, and the design of the intake manifold is also different. The Mercedes-Benz engine It is a water-cooled GER.The M274 is a 0-liter turbocharged engine, and the British Finiti uses the Q50L. Q50L is a medium-sized car under the British Finiti.

The internal structure is different: the m274 engine used by Mercedes-Benz adds an intake manifold and a vortex generator of water-cooled yurt, and adds a ternary catalyst; the Finiti m274 has only one ternary catalytic converter. Different emphasis on torque: Mercedes-Benz m274 has stronger torque at low speed; Finiti m274 tends to have high-speed output.

Benz's m274 engine has one more ternary catalyst than Finiti, and the design of the intake manifold is also different. Mercedes-Benz's engine uses water-cooled ger. The M274 is a 0-liter turbocharged engine, and the model used by the British Finniti is q50l. Q50l is a medium-sized car under the British Finiti.

In short, Infiniti uses a Mercedes-Benz engine! For example, Infiniti Q50 uses the engine of Mercedes-Benz M274 0T. Of course, the subsequent adjustment research and development will be completed by Infiniti.

Why does Q70 use m274 engine?Machine

Finiti's British Q70 adopts a 0T turbocharged engine model M274. Although this car uses a Mercedes-Benz engine, the post-tuning of the engine is done by the British Finiti. The engine used in this car has a world-recognized gold content, and the Mercedes-Benz M2740T engine has also won the title of Ward's top ten engines.

Infiniti Q70 uses a 0T turbocharged engine model M274. Although this car uses the engine of Mercedes-Benz, the later tuning of the engine was completed by Infiniti.

It is said that the interior is old, I like the physical button, but I don't like the LCD screen, and the LCD screen operation is locked. The starting and low-speed torque is insufficient, and it is obviously weak. The engine of 0 is noisy.Compared with Tianli, the q70 seat is hard. Only the last two doors of the four doors have self-aspiration, and it is difficult to control the closing force.

The engine code of Feniti q70 is 274a. The 0-liter turbocharged engine of Finiti q70 can output 211 horsepower and a maximum torque of 350 Nm. This engine can output maximum power at 5500 rpm and maximum torque at 1500 to 3500 rpm.

Disadvantages and advantages of Mercedes-Benz 274a engine

1. The advantage of a engine is that the engine material is very solid, the safety factor is very high, and the engine power is very strong and the operation is stable. The disadvantage is The fuel consumption of the engine is relatively high, and the price of the engine is relatively expensive and not cost-effective.Engine defects: the angle of the camshaft is abnormal.

2. The angle of the camshaft is abnormal. The symptoms are that the engine fault light starts and stops abnormally, the engine has abnormal noise and acceleration, the lag causes slow unlocking, resulting in the pin and VVT sprocket to be scratched, the locking failure will cause the rotor and the sprocket to be unable to mesh, the engine connecting rod is broken and the cylinder is broken, and the engine cylinder wall has The big hole affects the complete scrapping of the engine.

3. The defects of the M274 engine mainly include: 1. The angle of the camshaft is abnormal. It shows that the engine fault light is on, the start and stop is abnormal, the engine noise is abnormal, and the acceleration is abnormal. Stuck will cause unlocking delays and scratches on the pin and VVT sprocket. The failure of locking will cause the rotor and the sprocket to be unable to megge. When the vehicle is driving, it will produce a huge abnormal noise.
