Compared with the traditional automotive engine core components, engine high pressure fuel pipes have not received special attention for a long time. However, statistics show that in recent years, the failure cases of high pressure fuel pipes have been increasing, and their proportion has entered the automobile for years. The top ten in the number of engine parts failed, and there is an increasing trend.
The high pressure fuel pipe of the car has multiple parts, which are summarized as follows: steering system, brake braking system, and air conditioning system. Each system requires good quality, can withstand a certain high pressure strength, anti-corrosion and other characteristics.
The high pressure fuel pipe is a component of the high pressure fuel pipe. It is required that the fuel pipe needs to bear a certain fuel pressure and has certain fatigue strength to ensure the sealing requirements of the pipeline. The high pressure fuel pipe for the vehicle mainly appears in the high pressure injection diesel engine and the high pressure injection direct injection. The gasoline engine can withstand the oil pressure required during engine operation.
Compared with the traditional automotive engine core components, the high pressure fuel pipe of the engine has not received special attention for a long time. However, statistics show that the failure cases of high pressure fuel pipes have been increasing in recent years, and their proportion is also increasing. It has entered the top ten of the number of failures of automobile engine parts in successive years, and has an increasing trend.
How is the high pressure fuel pipe oil leakage caused? I will analyze it in detail for everyone today.1. The tube bursts.The reason for the bursting of the high pressure fuel pipe is generally that the fuel pipe manufacturer does not conduct the test before the assembly leaves the factory; at the ve
