【実用新案登録請求の範囲】[Scope of utility model registration request] 燃料を燃焼室の内周面の複数方向と底面の中法部分とに
向けて噴射させるとともに、上記燃焼等の底面部分には
窪み部を形成し、この窪み部の燃焼室の内周面に向けて
噴射された燃料の複数の噴射方向の間に対応する部分を
径方向中心から外力に向って次第に浅くなるガイド部に
形成したことを特徴とするディーゼルエンジン。In addition to injecting fuel in multiple directions on the inner peripheral surface of the combustion chamber and toward the middle part of the bottom surface, a recessed part is formed in the bottom part of the combustion chamber, and the inner peripheral surface of the combustion chamber in this recessed part is injected. A diesel engine characterized in that a portion corresponding to a plurality of injection directions of fuel injected toward the direction is formed as a guide portion that becomes gradually shallower from a radial center toward an external force.
