焼制御装置。 A deceleration operation state detection means for detecting a deceleration operation state, an engine rotation speed detection means for detecting an engine rotation speed, and a speed change amount calculation means for calculating an amount of change in the engine rotation speed based on the detected engine rotation speed. , when a deceleration operation state is detected and it is determined that the engine rotation speed is increasing, combustion control is performed based on the calculated amount of change in the engine rotation speed and the engine operation state immediately before the start of deceleration operation. The present invention is characterized by comprising a cylinder number setting means for setting the number of cylinders to be stopped or the number of cylinders to be subjected to combustion control, and a combustion control means for performing combustion control on a predetermined number of cylinders based on the set number of cylinders. Combustion control device for multi-cylinder internal combustion engine.
