Fuel injection controller for multi-cylinder internal-combustion engine

Abstract

Abstract PURPOSE:To execute reduced cylinder operation stably by providing means for disabling fuel injection with correspondence to the reduced cylinder pattern upon detection of idle operation and/or light load operation of internal-combustion engine. CONSTITUTION:Fuel injection is executed independently for respective cylinder with injection timing synchronous with the rotation of internal-combustion engine M1. Upon detection of idle operation and/or light load operation of internal-combustion engine through light load operation detecting means M2, means M3 will disable fuel injection with correspondence to cylinder reduction pattern where the injection timing for never executing fuel injection is preset while employing the injection times having relation with the number of cylinder as single period. Consequently, reduced cylinder operation can be executed stably.
