FUEL INJECTION AMOUNT CONTROLLER FOR INTERNAL COMBUSTION ENGINE

摘要

PROBLEM TO BE SOLVED: To suppress adverse effect applied on exhaust gas and obtain a stable operation condition by specifying a cylinder having unevenness in amount of fuel injection per cylinder accurately and compensating fuel based on angular acceleration of each cylinder and an O2feedback value obtained from a measured value of an O2sensor. SOLUTION: This fuel injection amount controller for the internal combustion engine provided with a plurality of cylinders for feedback-compensating amount of injection of fuel jetted by an injector capable of supplying fuel independently per cylinder for the internal combustion engine based on concentration of oxygen in an exhaust pipe is provided with an angular acceleration detection means 14 for detecting angular acceleration in an explosion process section per cylinder. The amount of fuel injection is compensated per cylinder based on a feedback compensation value and angular acceleration in the explosion stroke section of each cylinder detected by the angular acceleration detection means.
