て軽負荷時や無負荷時に部分気筒運転を指令する制御装
置と、この指令により燃料の供給が遮断され作動を休止
する休止側気筒と、常時作動する稼動側気筒とを備えた
多気筒エンジンにおいて、絞弁の開度と、変速機のギヤ
位置と、車速を検出するセンサをそれぞれ設け、絞弁が
全閉かつ変速機が中立位置で車速が所定値以下のときに
は、上記制御装置の運転条件判断機能を遅らせる遅延回
路を備えたことを特徴とする気筒数制御エンジン。A control device that determines the operating conditions of the engine and, based on the determination result, commands partial cylinder operation during light load or no load, and a cylinder on the idle side whose fuel supply is cut off and the operation is suspended in response to this command. In a multi-cylinder engine with a constantly operating cylinder, sensors are installed to detect the opening of the throttle valve, the gear position of the transmission, and the vehicle speed. An engine with a controlled number of cylinders, comprising a delay circuit that delays an operating condition determination function of the control device when a vehicle speed is below a predetermined value.
