Abstract
PURPOSE: To improve intake efficiency by allowing fuel to jet at a proper jet position, synchronized with engine revolution, and allowing a prescribed amount of fuel to be imbibed completely to each cylinder.
CONSTITUTION: The signal of a pulse generator 5 which generates the pulse corresponding to the cylinder of an engine is generated at the extreme advance position, and at the position from the advance position described above through a delaying circuit 6, fuel is injected by an jet determining circuit 9, with the pulse calculated by a calculating circuit 8 according to the engine state signal 7. When the injection position changing signal for advance or delay arrives, the delay time of an delaying circuit 6 is controlled so that injection is started at the position conforming to the specification demanded. Thus, the delay time of the delaying circuit 6 is varied according to the state of the engine, and injection starting time can be controlled.
