機関。 It has a main combustion chamber and a sub-combustion chamber that faces the fuel injection valve, and has a protrusion that projects from the top surface of the piston toward the sub-combustion chamber, as well as a base that fits this protrusion into the cylinder head. A first communication hole and a second communication hole are respectively formed in the protrusion to communicate the auxiliary combustion chamber and the main combustion chamber near the top dead center, and the second communication hole is connected to the protrusion when the piston is inserted into the protrusion. A vent hole is opened in a position where it is closed by the mouthpiece in the process of rising, and a vent hole that communicates with the main combustion chamber through the middle of the nozzle throat between the nozzle portion of the fuel injector and the auxiliary combustion chamber is opened in the cylinder. An indirect injection diesel engine characterized by the formation of a head.
