Title:
FUEL INJECTION QUANTITY CONTROL FOR INTERNAL-COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JPS6114446
Kind Code:
A
Abstract:
PURPOSE: To reduce uncomfortable fluctuation of rotation by obtaining the differential rotation before and after combustion and reducing the fuel supply to the cylinder such that the difference will be maximized.
CONSTITUTION: Fluctuation of variation ΔNi for each cylinder is operated in step 206. While correcting amount qi of fuel injection is updated in step 208 to reduce the injection for i-th cylinder having the maximum ΔNi determined in step 207. In step 209, correcting amounts of injection for three other cylinders are increased to maintain the average injection of all cylinders constant. Consequently, uncomfortable fluctuation of rotation can be reduced considerably.
