Claims (5)
- 均質燃焼時に吸気下死点近傍においてシリンダボアへ向けて噴射される燃料によりタンブル流を強める筒内噴射式火花点火内燃機関において、噴射燃料の測定又は推定温度が現在の燃料噴射圧力では噴射燃料の気筒内での減圧沸騰が発生しない設定上限値を上回る時には燃料噴射圧力を低下させ、前記測定又は推定温度が高いほど、燃料噴射圧力をより低下させることを特徴とする筒内噴射式火花点火内燃機関。
- 均質燃焼時に吸気下死点近傍においてシリンダボアへ向けて噴射される燃料によりタンブル流を強める筒内噴射式火花点火内燃機関において、噴射燃料の測定又は推定温度が現在の燃料噴射圧力では噴射燃料の気筒内での減圧沸騰が発生しない設定上限値を上回る時には、前記設定上限値以下となるように噴射燃料の温度を低下させることを特徴とする筒内噴射式火花点火内燃機関。
- 前記燃料噴射弁回りを空気流により冷却して噴射燃料の温度を低下させることを特徴とする請求項2に記載の筒内噴射式火花点火内燃機関。
- 噴射燃料の前記測定又は推定温度が設定下限値を下回る時には、前記設定下限値以上となるように噴射燃料の温度を上昇させることを特徴とする請求項1から3のいずれか一項に記載の筒内噴射式火花点火内燃機関。
- 前記燃料噴射弁の閉弁時に前記燃料噴射弁が開弁しないように通電して開弁アクチュエータを発熱させることにより噴射燃料の温度を上昇させることを特徴とする請求項4に記載の筒内噴射式火花点火内燃機関。
