摘要: A rotational speed parameter is detected in accordance with a rotational speed of the engine. A reference value of the rotational speed parameter is calculated. For each cylinder, an error between the reference value and the rotational speed parameter detected every predetermined crank angle is calculated as a relative speed parameter. For each cylinder, an integrated value is calculated by integrating the relative speed parameters over a predetermined period. For each cylinder, an average value per cylinder of the sum of the integrated values of all the cylinders is calculated. For each cylinder, an error between the integrated value of the cylinder and the average value is calculated. For each cylinder, the output of the engine is controlled in accordance with the error calculated for the cylinder such that variations in the output between the cylinders are suppressed.

摘要: A control system for an internal combustion engine having a throttle valve disposed in an intake passage of the engine is provided. A wide-open intake air amount, which is an intake air amount corresponding to a state where the throttle valve is fully opened, is calculated according to the engine rotational speed, and a theoretical intake air amount, which is an intake air amount corresponding to a state where no exhaust gas of the engine is recirculated to a combustion chamber of the engine, is calculated according to the wide-open intake air amount and the intake pressure. An intake air amount of the engine is detected or estimated, and an amount of the evaporative fuel/air mixture supplied through the evaporative fuel passage to the intake passage is calculated. An intake gas amount is calculated by correcting the intake air amount using the evaporative fuel/air mixture amount, and an exhaust gas recirculation ratio is calculated using the theoretical intake air amount and the intake gas amount. The engine is controlled using the calculated exhaust gas recirculation ratio.
