PROBLEM TO BE SOLVED: To enable a multi-cylinder engine 10 and the like to suppress occurrence of abnormal sound while performing a light load operation of the engine 10 from the viewpoint of fuel consumption or charge restriction, when there is no charging request to a battery and is a heating request from a crew member at the time of stop of a hybrid vehicle, or there is a charging request to a battery and charging restriction thereto.SOLUTION: A multi-cylinder engine control system for a hybrid vehicle controls, when variation range of output torque between cylinders of the engine 10 is larger than a reference value, output torque of the cylinders except a cylinder having the highest output torque to match to the output torque of the cylinder having the highest output torque if temperature of coolant of the engine 10 is less than a prescribed temperature, and controls the output torque of the cylinders except a cylinder having the lowest output torque to match to the output torque of the cylinder having the lowest output torque if the temperature of the coolant thereof is the prescribed temperature or higher.SELECTED DRAWING: Figure 2

    【課題】ハイブリッド車の停車時において、バッテリへの充電要求がなくかつ乗員の暖房要求があるか、又は、バッテリへの充電要求がありかつ該バッテリの充電制限があるときに、燃費や充電制限の観点から多気筒エンジン10を軽負荷運転しつつ、該エンジン10等での異音の発生を抑制できるようにする。【解決手段】エンジン10の気筒間の出力トルクのばらつき幅が基準値よりも大きくなったときにおいて、エンジン10の冷却水の温度が所定温度よりも低いときには、出力トルクが最も高い気筒の出力トルクに、他の気筒の出力トルクを合わせるべく、該他の気筒の出力トルクを調整する一方、上記冷却水の温度が上記所定温度以上であるときには、出力トルクが最も低い気筒の出力トルクに、他の気筒の出力トルクを合わせるべく、該他の気筒の出力トルクを調整する。【選択図】図2
