CONTROL APPARATUS FOR DIRECT INJECTION ENGINE

摘要

A cylinder-injection-engine control apparatus includes a fuel injection controller that executes air purge control for performing fuel injection in an intake stroke if fuel pressure is below a predetermined pressure when an engine starts. When executing the air purge control, the fuel injection controller makes a fuel injection time of an injector longer than when the fuel pressure is higher than or equal to the predetermined pressure. When executing the air purge control, if the amount of fuel in a fuel tank is larger than or equal to a predetermined amount and an integrated value of a fuel injection amount (integrated injection amount) since start of the fuel injection is larger than or equal to a predetermined value, the fuel injection controller stops the air purge control.

1. A control apparatus for a direct injection engine, the control apparatus comprising:
a fuel pressure detector that detects fuel pressure of fuel to be fed to at least one injector that injects the fuel into a corresponding cylinder of the engine; and a fuel injection controller that executes air purge control for performing fuel injection in an intake stroke of the engine if the fuel pressure detected by the fuel pressure detector is below a predetermined pressure when the engine starts.
