Abstract:
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.
