Everyone is saying that power shortage is only a feeling, because there is no actual measurement of engine torque, power or vehicle driving force data support. But it is not the water that is not felt. It may come from the driver's years of driving experience or the comparison of the driving experience before and after.

Experience tells us that the lack of sense of vehicle power, is not the problem of engine and vehicle, for other reasons, such as brake system, transmission system, electrical system, vehicle configuration, even driving method is improper and so on, therefore, consider the problem of processing from the macro, micro focus, comprehensive analysis, stepwise.

From the reasons, mechanisms, feelings, experience and other perspectives for more detailed description, to help you quickly find the lesions.

– basic working methods

ask

A truck repair factory hospital, vehicle maintenance maintenance technician is a doctor, as a doctor, you should first understand the vehicle fault phenomenon, pre maintenance, vehicle use environment, vehicle configuration information, fault occurrence history etc..

at

Is to observe, observe the vehicle, the North ran V3 accessories, parts and other aspects of the appearance, but also in accordance with the "ask" the situation, targeted observation.

smell

Just listen to the voice of the big assembly, especially listen to the voice of the engine running north of the v3.

cut

It is fault diagnosis and data measurement, which can be diagnosed by the decoder, and also can be diagnosed by various special measuring equipment.

In short, the basic purpose is to narrow the scope of the investigation, targeted to improve the efficiency of maintenance.

The following will be carried out around the four word:

Fault phenomenon: new car power is better, late power gradually attenuated, more and more poor.

This fault phenomenon holds a large proportion of failure, long or short. Elderly one hundred thousand, hundreds of thousands of kilometers; short tens of thousands of kilometers ranging, generally around one hundred thousand kilometers. The main performance is the lack of vehicle one or two files; increase and decrease after the engine speed is slow; North Benz V3 engine accessories sound muffled; fuel consumption increased; driving up feeling tired; even when the load, climb slope have a little smoke and so on.
