| description | To enable cranking assist in restarting an engine even in a port injection type engine, to reduce power consumption and to improve fuel consumption of cranking means such as a motor connected to the engine, and to surely start the engine.SOLUTION: A cylinder performing an expansion stroke in stop of an engine is estimated (step S3) when an engine stop condition is established in idle stop control (step S2), and a piston position of the cylinder estimated in the step S3 is returned close to a bottom dead center to start a compression stroke before the expansion stroke (step S6), when a specific start condition is established (YES in step S5), to start the engine (step S7).SELECTED DRAWING: Figure 3
【課題】ポート噴射式エンジンであっても、エンジン再始動時のクランキングアシストを可能にし、エンジンに結合されたモータ等のクランキング手段の消費電力削減と燃費向上を図るとともに、確実なエンジン始動を図れるようにする。【解決手段】アイドルストップ制御においてエンジン停止条件が成立すると（ステップＳ２）エンジン停止時に膨張行程となる気筒が推定され（ステップＳ３）、特定始動条件が成立したとき（ステップＳ５のＹＥＳ）には、ステップＳ３で推定された気筒におけるピストン位置が、膨張行程手前の圧縮行程が開始される下死点近傍まで戻されて（ステップＳ６）、エンジン始動が行われる（ステップＳ７）。【選択図】図３ |
