Abstract

PURPOSE: To reduce NOx and noise and improve the power of a Diesel engine in the direct injection type cylinder combustion chamber by forming high temperature wall surface as long as possible in the combustion chamber to flow injection fuel along the wall surface.
CONSTITUTION: The contact surface 3 of the cylinder 3 of a cylinder head 1 is formed substantially flat, a sleeve 5 internally engaged with a fuel injection valve 4 is projected from the center of the contact surface 3, and the nozzle port of the nozzle 6 for the injection valve is provided in the inner hole toward the projected end side. On the other hand, an air passage 8 of axial hole functioning also as the space for receiving the sleeve 5 is perforated at the upper center of the piston 7, and a piston cavity 10 opened diametrically at the upper portion is perforated at the lower portion of the passage 8. The peripheral wall of standing conical projection 9 at the bottom center of the cavity 10 is formed to radially introduce fuel jet stream from the lower end of the sleeve 5 to thereby form a shape for circulating the jet stream toward the passage 8 side in the shape of the inner wall surface.
