COMBUSTION CONTROL DEVICE FOR ON-VEHICLE INTERNAL COMBUSTION ENGINE

摘要

PROBLEM TO BE SOLVED: To provide a combustion device for an on-vehicle internal combustion engine capable of suitably suppressing deterioration of drivability caused by the changeover of a combustion form. SOLUTION: The internal combustion engine 10 is controlled to perform stratified combustion during low speed or low load operation and to perform uniform combustion during medium or higher speed and medium-high load operation. During idling operation conditioned on vehicle speed detected by a vehicle speed sensor 4 being zero, the internal combustion engine 10 is controlled to perform uniform combustion so as to prevent rattling sound from a manual transmission 30. The changeover of a combustion form from uniform combustion to stratified combustion following the start of a vehicle is made on condition that the depressed state of a clutch pedal 45b is detected by a clutch sensor 45 and the nondepressed state of an accelerator pedal 42a is detected by an idle switch 43.
