Japanese Patent JP4475221
Kind Code:

Abstract:
An engine includes an in-cylinder injector injecting fuel into a cylinder, a port injector injecting fuel into an intake manifold, and a valve-opening-characteristic changing mechanism changing at least lift or opening duration of an intake valve. When the engine is in a predetermined operating region and the valve-opening-characteristic changing mechanism decreases the lift or the opening duration of the intake valve, the ratio of fuel injected by the in-cylinder injector is increased according to an amount of the decrease of the lift or the opening duration and accordingly a decrease in tumble ratio is compensated for by the injection flow.
