Multiple-cylinder engine combustion control apparatus and method of controlling said engine.

摘要

A multiple-cylinder engine combustion control apparatus and method of controlling the engine is arranged to detect variation in the rotational speed of the engine by a crank shaft sensor or a cam shaft sensor and to determine a particular cylinder causing the variation in rotational speed by a microprocessor (12). The microprocessor (12) is arranged to modify the operating condition of the cylinder causing the variation in engine rotational speed by varying at least one of the engine ignition timing and the fuel injection pulse width so as to correct the rotational speed variation.
