Electronic fuel injection type diesel engine

An electronic fuel injection type diesel engine including a cylinder, a cylinder head, a vortex chamber in the cylinder head, a main combustion chamber in the cylinder, a communication port for communicating the main combustion chamber and the vortex chamber, an insertion hole in the cylinder head toward the vortex chamber, and an electronic fuel injection type fuel injector inserted into the insertion hole, the electronic fuel injection type diesel engine comprising:

• a sleeve protruding from the insertion hole to an outside of the cylinder head;
• and
• a pressure receiving surface provided at a protruding end portion of the sleeve,
• wherein the fuel injector includes a main body portion having a large diameter, a nozzle portion having a small diameter, and a pressing surface formed at a step portion between the main body portion and the nozzle portion, and
• wherein the nozzle portion of the fuel injector is inserted from an inside of the sleeve to an inside of the insertion hole, the fuel injector is pressed toward the vortex chamber by a pressing force, and the pressing force applied to the fuel injector is received by the pressure receiving surface of the sleeve from the pressing surface of the fuel injector via a washer.
