Abstract
【解決手段】各気筒の内燃機関の始動時におけるピストンの停止位置が、吸気期間Tsの開始後で、かつ吸気TDCの略90°ATDCよりも前の期間T2にあるか否かを判定する。また、期間T2にピストンの停止位置がある気筒の気筒内温度が規定値よりも高いか否かを、雰囲気温度、エンジン水温、内燃機関停止から再始動条件が成立するまでの経過時間から推定する。期間T2にピストンの停止位置があり、気筒内温度が規定値よりも高いと推定されるときには、クランキング時に、期間T2内の燃料噴射期間F2において燃料を複数回に分けて噴射する。
【選択図】図2
Description
図1は、本発明の一実施形態である内燃機関の構成を模式的に示すブロック図である。なお、図1には1つの気筒の模式的、部分的な断面図のみが示されるが、内燃機関は従来周知のように複数の気筒を備える。また、内燃機関は、例えばアイドリングストップ機能を備えた車両において用いられる。
図2は、アイドリングストップ制御における内燃機関停止後、再始動時における燃料噴射のタイミングを示すタイミングチャートである。
