Description
Claims (3)
- 4つの気筒と、前記各気筒にそれぞれ設置されて筒内へ直接燃料を噴射する第1のノズルと、前記各気筒の吸気ポートにそれぞれ設置されて前記吸気ポートへ燃料を噴射する第2のノズルと、前記各気筒における燃料噴射を制御する制御装置と、クランク角度がどの位置であるか検知する角度センサと、を備えるエンジンであって、
前記制御装置は、前記角度センサによって検出されるクランク角度を基に前記各気筒がどの行程にあるかを識別し、このエンジンの始動制御における各気筒の最初の燃料噴射を、始動開始の時に排気行程および圧縮行程に位置した気筒に対して前記始動開始と同時にそれぞれ前記第2のノズルのみから実施し、前記始動開始の時に膨張行程に位置した気筒に対して最初に訪れる圧縮行程で前記第1のノズルのみから実施し、前記始動開始の時に吸気行程に位置した気筒に対して二度目に訪れる圧縮行程で前記第1のノズルのみから実施する
ことを特徴とするエンジン。 - 前記制御装置は、すべての気筒の初爆が完了した後、このエンジンの冷却水の温度が一定値以上となるまですべての気筒に対して前記第1のノズルのみから燃料を噴射する
ことを特徴とする請求項1に記載されたエンジン。 - 前記制御装置は、このエンジンの冷却水の温度が一定値以上となった後、すべての気筒に対して前記第2のノズルのみから燃料を噴射する
ことを特徴とする請求項2に記載されたエンジン。
