Abstract
A high-pressure pump () is provided which is drivingly connected to an engine output shaft () and delivers fuel to an injector () through a delivery pipe () based on the rotation of the output shaft (). The high-pressure pump () includes an electromagnetic valve () that adjusts, based on the engine operating state, a fuel delivery amount within an adjustable range that changes according to a rotation speed of the engine output shaft (). When an abnormality is detected in the electromagnetic valve (), the rotation speed of the engine output shaft () is restricted to equal to or less than a reference engine speed (NT).
