CONTROL DEVICE OF INTERNAL COMBUSTION ENGINE

To suppress the smoldering of an ignition plug of an internal combustion engine, and to avoid a start delay or a start failure.SOLUTION: A control device of an internal combustion engine is constituted such that information related to an in-cylinder temperature immediately before a stop of an operation of the internal combustion engine is stored and held, and after the operation is started by cold-operating the internal combustion engine, when the in-cylinder temperature is a low temperature which is equal to or lower than a determination value in a situation that an engine rotation number or a vehicle speed is higher than a prescribed value, a fuel injection amount is reduced. By this constitution, an air-fuel ratio is leaned, a temperature rise of the in-cylinder temperature is promoted, and deposits adhering to the ignition plug can be thereby easily combusted.SELECTED DRAWING: Figure 3 【課題】内燃機関の点火プラグのくすぶりを抑制し、始動遅延または始動不良を回避する。【解決手段】内燃機関の運転の停止直前における筒内温度に関する情報を記憶保持し、当該内燃機関を冷間始動して運転を開始した後、エンジン回転数または車速が所定以上に高い状況下において、前記筒内温度が判定値以下の低温であった場合、燃料噴射量を減量して制御する内燃機関の制御装置を構成した。これにより、空燃比がリーン化し、筒内温度の昇温が促進されて、点火プラグに付着したデポジットが燃焼しやすくなる。【選択図】図３
