The invention provides a method for operating an engine in an intermittent combustion mode and an engine control device. An intermittent combustion mode is executed while cyclically switching an intermittent firing pattern in such a manner that the skipped-cylinder interval is changed by one cylinder at a time. Furthermore, the intermittent firing pattern is switched in such a manner that the fired cylinder ratio in one cycle of switching of the intermittent firing pattern becomes equal to a target fired cylinder ratio. This suppresses the occurrence of vibration and noise having low frequencies that tend to disturb the occupant while limiting an increase in the rotational fluctuation of the engine. 本发明涉及用于以间歇燃烧模式运行发动机的方法和发动机控制装置。执行间歇燃烧模式，同时周期地切换间歇点火型式，使得跳过气缸间隔每次改变个气缸。此外，切换间歇点火型式，使得在间歇点火型式的切换的个周期中的点火气缸比变为等于目标点火气缸比。这抑制了具有易于干扰乘员的低频的振动和噪声的发生，同时限制了发动机旋转波动的增加。
