The fuel injectors are connected to the high pressure fuel rail and deliver a calibrated amount of fuel directly into the combustion chamber. The piezo actuator is commanded on by the PCM during the main injection stage for approximately 0-1000 microseconds. The fuel injectors on and off time is controlled by the piezo actuator device which allows extreme precision during the injection cycle. For additional information on fuel injection operation, refer to FUEL SYSTEM .
