An engine control system comprises engine revolution speed detecting means for producing an output signal of engine revolution data of the engine, intake air temperature detecting means for producing an output signal of intake air temperature data of the intake manifold, cylinder operation condition determining means for producing an output signal of the cylinder operating condition data for each of cylinders assembled in the engine, intake air pressure detecting means for producing an output signal of air pressure data of the intake manifold, intake air ratio compensation value calculating means for calculating on the basis of the cylinder operation data of each of the cylinders an intake air ratio compensation value derived from the air pressure data of air in the intake manifold and the engine revolution speed data of the engine, and intake air quantity calculating means for calculating an intake air quantity on the basis of the intake air ratio compensation value. An engine control method comprising the steps of detecting engine revolution data of the engine and intake air temperature data of the intake manifold, determining cylinder operation data of the engine, detecting intake air pressure of air in the intake manifold, calculating on the basis of the cylinder operation data an intake air ratio compensation value derived from the air pressure data of the manifold and the engine revolution speed data of the engine, and calculating an intake air quantity of air to be introduced into each of the cylinders of the engine on the basis of the intake air ratio compensation value. The intake air quantity can thus be desirably adequately calculated on the basis of the intake air ratio compensation value calculated by the system and method as above. <IMAGE> |
