CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE

PROBLEM TO BE SOLVED: To feed EGR gas into a cylinder from the first cranking cycle of a re-starting operation so as to restrict vibration at the time of starting in operation of an engine intermittent operation.SOLUTION: A control device for an internal combustion engine of this invention is applied to the internal combustion engine provided with an EGR device and a throttle valve. The EGR device comprises an intake passage and an exhaust passage of the internal combustion engine; an EGR valve installed at the EGR passage so as to cause a part of the exhaust gas to be fed from the exhaust passage into the intake passage as EGR gas. The throttle valve is installed at the intake passage. The control device for an internal combustion engine is constituted in such a way that when a request for intermittent stop for the internal combustion engine is applied, the EGR valve is opened after the throttle valve is closed and then the EGR valve is opened to stop an operation of the internal combustion engine.SELECTED DRAWING: Figure 3 【課題】エンジン間欠運転における始動時の振動を抑制するため、再始動時のクランキング１サイクル目から筒内にＥＧＲガスを導入する。【解決手段】本発明の内燃機関の制御装置は、ＥＧＲ装置とスロットルバルブとを備える内燃機関に適用される。ＥＧＲ装置は、内燃機関の吸気通路と排気通路とを接続するＥＧＲ通路と、ＥＧＲ通路に設置されたＥＧＲバルブとを備え、排気通路から吸気通路に排気の一部をＥＧＲガスとして流入させる。スロットルバルブは、吸気通路に配置される。内燃機関の制御装置は、内燃機関の間欠停止要求があった場合、スロットルバルブを閉弁した後で、ＥＧＲバルブを開弁して、内燃機関を停止するように構成される。【選択図】図３
