ford constant voltage regulator gauge value
The performance of Ford fuel constant voltage regulator is that the oil pressure is coordinated by the spring and the vacuum degree of the air chamber. The ford constant voltage regulator gauge value is 1.2-1.5bar. When the oil pressure is higher than the standard value, the high-pressure fuel will push the diaphragm upward, open the ball valve, and the excess fuel will flow back to the tank through the return pipe. When the pressure is lower than the standard value, the spring will press the diaphragm to close the ball valve and stop oil return.
Adjust the fuel pressure to the injector so that the difference between the fuel pressure in the fuel circuit and the intake pipe pressure remains constant. In this way, the amount of fuel injected from the injector only depends on the opening time of the injector, so that the electronic control unit can accurately control the fuel injection amount by controlling the electrical pulse width.
The function of the pressure regulator is to keep the pressure in the oil circuit constant. If the oil pressure is too low, the fuel injector will inject too little or no fuel. If the oil pressure is too high, the oil circuit will be damaged or the fuel injector will be damaged. The working principle of the fuel regulator is that the oil pressure is coordinated by the spring and the vacuum degree of the air chamber. When the oil pressure is higher than the standard value, the high-pressure fuel will push the diaphragm upward, the ball valve will open, and the excess fuel will flow back to the tank through the return pipe.
The rupture of the vacuum diaphragm of the oil pressure regulator will cause fuel to leak to the intake pipe through the vacuum hose, resulting in high fuel consumption, damage to the vacuum diaphragm of the exhaust pressure regulator, or air leakage of the vacuum hose, which will lead to unbalanced oil return of the regulator, inaccurate fuel injection of the engine, poor engine operation, and generally the engine fault light is on, while the oil pressure regulator is actually a flow safety valve controlled by the diaphragm.The opening of the transfer valve is controlled by the diaphragm to maintain the pressure balance between the upper chamber and the lower fuel chamber. Pay attention to smoke, difficulty in starting the engine and other faults. The function of the economizer is not only to keep the oil circuit pressure constant.
