Background technique：
Vehicle fuel supplies owner will be by fuel tank, low-voltage fuel pipe, oil transfer pump, fuel filter, injection pump (rotor point
With pump, equipped with injection advance adjuster and automatic start excess fuel device etc.), the composition such as high-pressure oil pipe and fuel injector.
The working principle of oil supply system is that fuel oil is sucked out in oil transfer pump from fuel tank, reaches and supplies after fuel filter
Oil pump oil suction chamber oil feed pump is vane type, its effect is the increase of foundation engine transmission to improve fuel pressure, is then fired
Oil reaches pressure regulator valve, this valve is used to adjust the fuel pressure in injection pump；Distributor plunger progress improves oil pressure, and passes through high pressure
Fuel oil is sent into fuel injector by oil pipe, and the fuel oil oozed out from fuel injector is recycled by oil return valve, and sends fuel tank back to.
In the process of work, if improper use will appear deflagration phenomenon, since the pressure of fuel tank leads to greatly temperature
Security risk caused by excessively high or fuel dispenser pressure is excessive is larger.Existing processing method be to fuel feed system into
Row disassembly measures piece by piece, the more troublesome and inefficiency of this detection.
