Abstract: In the common rail system, fuel is distributed to the injectors from a high pressure accumulator, called the rail. If there is an issue, then the automobile's check engine light comes on. The heat of this compression, combined with residual heat in the piston and cylinder head from the previous power stroke, ignites the fuel. Unlike unit injectors whose pressure varies with the "rise time" of the injection event, common rail systems are supplied by constant pressure pumps that assure instant high-pressure response for each injection event. This pressure is controlled by an internal pressure regulator in the pump and monitored by a fuel rail pressure sensor. RAC was called, 6 faults. Rail Pressure Feedback Mode Key_on_time>0.
