付デイーゼルエンジン。 A diesel engine with an ignition assist device that uses low cetane fuel and injects the fuel from a fuel injection nozzle, collides with a collision part protruding inside a cavity at the top of the piston, scatters the fuel, and ignites it with an ignition assist device. In the above, the top of the collision part is shaped to form a spray pattern in which the fuel colliding with the top forms a good mixture for ignition near the ignition auxiliary device and allows the ignited flame to propagate well. A diesel engine with an ignition assist device.
