Claims (1)
- 一対の吸気バルブを備え、当該一対の吸気バルブを異なるタイミングでリフトさせるリフト手段を備えた筒内直接噴射式のものにおいて、
何れか一方の吸気バルブの開弁時から所定時間経過後に他方の吸気バルブを開弁し、
当該他方の吸気バルブのリフト量がピークになるタイミング近傍で燃料を噴射する内燃機関であって、
前記何れか一方の吸気バルブが開弁すると燃焼室の内壁に沿うように一方向のスワール流が起こるとともに他方の吸気バルブが開弁すると燃焼室の内壁に沿うように前記一方向とは逆方向のスワール流が起こるものであり、
前記燃料の噴射が、前記一方向のスワール流及び前記逆方向のスワール流の衝突が最も激しく起こる箇所へ向けて燃料噴射を行う下方噴射口による燃料噴射と、点火プラグ近傍へ向けた燃料噴射を行う上方噴射口による燃料噴射とを併せて行うインジェクタによって行われることを特徴とする内燃機関。
