料を直接噴射させる直接噴射式内燃機関において、ピス
トンが上死点に至るときにピストンとシリンダヘッドと
の間のスキッシュクリアランスに生じるスキッシュ流を
前記燃料噴射弁の噴口部近傍に集中させるスキッシュ流
の集中導入路を、ピストン頭部に形成してなる直接噴射
式内燃機関。In a direct injection internal combustion engine, in which fuel is injected directly into the combustion chamber from a fuel injection valve facing the top of the cylinder, the squish flow that occurs in the squish clearance between the piston and the cylinder head when the piston reaches top dead center is A direct injection internal combustion engine, wherein a concentrated introduction path for squish flow to be concentrated near the nozzle of the fuel injection valve is formed in the piston head.
