Steuerverfahren für eine Brennkraftmaschine mit Direkteinspritzung

摘要

A direct injection engine control system of a type that controls indirectly an air-to-fuel ratio in a combustion chamber by regulating a quantity of exhaust gas that is recirculated delivers fuel more than one thirds of a total quantity of fuel injection to be delivered in one combustion cycle through early split fuel injection at a crank angle 90? before top dead center of a compression stroke and the remaining part through later split fuel injection at a point of the compression stroke in an engine operating region of lower engine speeds and higher than moderate engine loads or upon an occurrence of transition to accelerative drive state from ordinary drive state.
