Gas pressure regulator maintenance
The fuel pressure regulator is referred to as the oil return valve, automobile fuel injection EFI system is one of the commonly used components.
The effect of gas pressure regulator
Fuel pressure regulating device is adjusted to fuel injection device of the fuel pressure and the oil in the fuel pressure and the intake pipe pressure difference remains constant, so from the amount of fuel injectors to spray will only depending on injector opening time, electronic control unit can pass control of electric pulse width to precise control of the injection quantity.
Gas pressure regulator
Gasoline pressure regulation and influence for the presence of fault
EFI car to the fuel pressure is constant, computer can control the fuel injection pulse width, also is the fuel injector opening time, you can control the fuel injection quantity of the.
A certain pressure, injector opening time is longer, the greater the amount of fuel injection, on the contrary, the shorter the time, the injection quantity is less.
If the fuel pressure regulator problems, so the accuracy is directly related to the amount of fuel injection.
Fuel pressure is too low, it will cause the vehicle idling low and high speed for oil is not the feeling, serious will cause difficulty in starting may not even be able to boot. The summer air conditioning to drive.
Fuel pressure is too high, will cause the vehicle idling, acceleration pedal too sensitive.
So, under the gas pressure regulator working condition is very necessary.
