ENGINE SPEED CONTROLLER OF INTERNAL COMBUSTION ENGINE, AND INTERNAL COMBUSTION ENGINE COMPRISING IT

摘要

When an engine speed in the expansion stroke of each cylinder is calculated from the time required for the crank angle to rotate from the compression top dead center to a specified angle of that cylinder and stored, and then the stored engine speeds for an immediately preceding cylinder and cylinders preceding it are averaged for use as an engine speed to be fed back in order to determine a fuel injection amount, how many past cylinders are to be subjected to averaging retroactively is determined depending on the operating state of the engine.
