Since the pressure of the diesel engine fuel system is generated by the fuel pump, the rail pressure is related to the fuel pump. The fuel pump of the Perkins 1606 diesel engine is controlled by the fuel pump control unit, which adjusts the rail pressure by adjusting the output of the fuel pump.
The rail pressure sensor monitors the rail pressure and sends a signal to the engine control unit. The engine control unit calculates the required amount and time of fuel injection based on the rail pressure signal and other sensor signals, such as engine speed and intake pressure, and controls the injector to inject the appropriate amount of diesel fuel into the combustion chamber.
Rail pressures that are too high or too low can lead to engine failure. If the rail pressure is too high, it will lead to poor atomization of fuel injection, so that the diesel cannot be fully combusted, thus affecting the power and economy of the engine. If the rail pressure is too low, it will cause the engine to stall or start difficult, and at the same time increase diesel emissions.
Therefore, the adjustment and maintenance of the fuel rail pressure of the Perkins 1606 diesel engine assembly is essential to ensure the normal operation and performance of the engine. In actual use, the rail pressure should be reasonably adjusted according to the working state and performance requirements of the engine to ensure the economy and reliability of the engine.
