What is the total power of the automobile in Chengdu?

Generalized automobile powertrain includes engine, gearbox, transmission shaft, differential, clutch and so on.

Powertrain refers to a series of parts that generate power on the vehicle and transmit it to the road surface, including engine, gearbox, transmission shaft, differential and clutch in a broad sense.

But generally speaking, powertrain only refers to the engine, transmission and other components integrated into the transmission, such as clutch/front differential.

As one of the core components of new energy vehicles, electric drive has an important influence on the performance of new energy vehicles. Gao Dawei, a professor in the automotive department of Tsinghua University, said that electric drive is of great significance to the power, economy, comfort, safety, reliability and durability of new energy vehicles.

To improve the technical level and quality of electric drive, we need to start with six key technologies: driving ability, driving efficiency, control accuracy, system stability, electromagnetic performance and working life. In addition, from the demand of industrialization, low cost, miniaturization and intelligence are the most important.

Precautions for replacing engine assembly:

1, when replacing the engine, you should first pay attention to the relevant procedures of the engine, whether there is a corresponding certificate, whether its packaging is complete, and whether there is a clear mark on the wooden box.

2. In principle, the engine should be replaced at the vehicle management office, and the engine number should be a new number. Generally, the original number is mainly because the engine has no certificate or avoids the complicated procedures of change.

But this is not allowed. If it is found during the car inspection, it will not be possible to conduct the car inspection. After replacement, check whether the engine wiring harness and pipeline are messy, and carry out the running-in according to the running-in standards of new cars.
