Title: Fuel supply controller of internal combustion engine
Inventor: NAKANIWA SHINPEI
IPC: F02D41/04
Filed: 1989-04-11
Abstract: PURPOSE:To prevent failure in setting the amount of compensation and deterioration in an air-fuel ratio controlling ability caused thereby by setting the amount of compensation for fuel supply through the amount of engine load variation and through the time it takes to a predetermined crank angle position, and by prohibiting compensation at the time of low rotation. CONSTITUTION:The amount of fuel supply is set by a fuel supply amount setting means B based on the intake amount or intake pressure by a driving condition detecting means A and the engine rotational speed. The amount of engine load variation is determined by an engine load variation calculating means C, based on the intake system opening area and on the engine rotational speed, while the amount of compensation for the fuel supply is determined by a compensation amount calculating means D based on the time H it takes from the calculation to a predetermined crank angle position. When the compensation amount exceeds a predetermined limit amount, the compensation amount is controlled to a predetermined value by a compensation amount control means E. The control is performed by a fuel supply control means F based on the compensated amount of fuel supply. When the engine rotational speed is not more than a predetermined value, compensation can be forced to be prohibited by a compensation prohibiting means G. Deterioration in air-fuel ratio control ability can thus be prevented.
