This signal tells the PCM that the engine is running. The PCM keeps the fuel pump relay closed and the fuel pump running. 当发动机曲柄转动和启动时,PCM接收一个点火信息,或“转速”(转速表)信号。这个信号告知PCM引擎正在运行。PCM保持燃油泵继电器关闭和燃油泵运转。 Some vehicles have an inertia ...
The main thing is what the voltage is with the engine running. I had my father with the multimeter at the pump connector and he said he never saw the voltage go up when the car was priming, it stayed at nearly zero the whole time. ...

This stupid van... first the fuel pump went and was replaced, not once but TWICE. Then my mechanic had to replace the fuel pump relay switch no less than 4 times. He said there is something wrong with the electrical lines? - Lindsey R., Harrisburg, PA, US MaximizeAbout...
For testing, the injectors are wired up to an electric injector tester, which is one of the few off-the-shelf components in the build. The fuel pump and injectors are powered by the 12 volt rail of a scrapped PC power supply. Just being able to watch the spray pattern is often enough...
Based on simple electronic control of the fuel pump the pressure regulator keeps the fuel supply pressure in the high-pressure side control pressure region during hot restarting and high load running of the engine and thereby suppresses the arrival of fuel vapor at the injectors and improves the ...
An alternative is to use a recirculation compressor, either by itself or in combination with a jet pump. The recirculation compressor keeps the fuel cell anode gas well mixed even when the fuel cell is running at very low power. Design of the compressor is challenging. It must operate with ...
In my first Spartan race years ago, I had no idea what to expect (outside of studying the obstacles) and the imagined possibility of all the little things outside of running and obstacles that could go wrong made me uncomfortable. Ahh, what I wish I knew then that I know now! I ...
This is basically a short-term reservoir that keeps the fuel-supply pressure constant and also irons out the pulses of fuel coming up from the pump. From the accumulator , the fuel passes through a paper element filter and then feeds into the fuel-metering control unit, also known as the ...
A fuel pump and a method for controlling a fuel pump. At least two pumps run at a mutual phase displacement such that they are able to receive fuel during different periods of time.
