Abstract
A fuel pump suctions fuel from a fuel tank and discharges the fuel. A discharge metering valve regulates an amount of the discharged fuel out of the suctioned fuel. The discharged amount is regulated by operating closing timing for closing the discharge metering valve through energization of the discharge metering valve. The fuel discharged by the fuel pump is pressure-fed to a common rail. A rotation angle interval between energizing operations of the discharge metering valve is lengthened when rotation speed of an output shaft of a diesel engine is high. Thus, a residual magnetic flux in the discharge metering valve is reduced. As a result, control of the fuel pressure can be suitably performed.
