Abstract
Provision is made to avoid a fuel discharge timing and a fuel injection timing during the ordinary operation of the engine from being limited, by, upon the activation of an engine, making a high-pressure fuel pump perform high-pressure-fuel discharge operation prior to initial fuel discharge operation by a fuel injection valve and based on the condition of the resultant fuel-pressure rise, performing a diagnosis on whether or not a malfunction exists in a high-pressure fuel system.
