Inventor: KIKUTANI YUKIFUMI
IPC: F02D41/40
Filed: 2001-04-27
Abstract: PROBLEM TO BE SOLVED: To avoid increase in the burden of the processing which an engine control part (ECU) performs by refraining from execution by interruption of both the computing process of injection amounts and/or the injection timing and the output set in synchronization with the engine rotation pulses by the engine control part (ECU) in a multi-stage injection control including the pre- injection, main injection, after-injection for enhancement of the fuel economy of the engine and/or a reduction of the emission.
