Claims (1)
間に形成された単一燃焼室に、燃料噴射ノズルから燃料
を直接噴射して燃焼させることによりピ支トンを駆動す
るようにした直接噴射式ディーゼルエンジンにおいて、
燃料噴射ノズルの先端外周部に、先端面が円錐状に拡開
した拡開凹面に形成された偏流スリーブを嵌装し、この
拡開凹面により燃料噴霧流の少くとも一部の射出方向を
規制して燃料噴霧流が前記キャビティの外部に流出しな
いようにしたことを特徴とする直接噴射式％式％A direct injection diesel engine that drives a piston by directly injecting fuel from a fuel injection nozzle into a single combustion chamber formed between the top surface of the piston and the cylinder head, which has a cavity, and combusting it. In,
A deflection sleeve formed into an expanded concave surface with a conically expanded tip surface is fitted to the outer periphery of the tip of the fuel injection nozzle, and the injection direction of at least a portion of the fuel spray flow is regulated by the expanded concave surface. Direct injection type % type % characterized in that the fuel spray flow is prevented from flowing out of the cavity.
