MULTICYLINDER INTERNAL COMBUSTION ENGINE HAVING SYSTEM FOR VARIABLE OPERATION OF INTAKE VALVE AND COMPENSATION FOR DIFFERENCE IN TORQUE GENERATED BY CYLINDER, AND CONTROL METHOD EXECUTED IN THIS ENGINE

摘要

PROBLEM TO BE SOLVED: To restrain irregularity of a rotating speed of an engine shaft by compensating for a difference in torque generated in the respective cylinders, in a multicylinder internal combustion engine having a variable operation system of an intake valve.

SOLUTION: A control means analyzes a rotating speed ω of the engine, determines a signal ΔTORQUE of indicating the difference in the torque generated in the respective cylinders, calculates an air volume correction value ΔAIR so that the torque with every cylinder mutually becomes the substantially same, and outputs a signal Δα of controlling opening of the intake valve.
