See full text

A diesel engine in which a lubrication oil on the wall surface of the cylinder liner is prevented from being burned and diluted, and a smoke resulting from the local lack of air in the combustion chamber is also prevented from being generated. The diesel engine comprises a group injection hole nozzle 20 and a piston 110. A step 115 having a height gradually increased toward the radial outer circumference of the piston is formed over the entire circumference of the top surface 111 of the piston. Furthermore, a tilted part 115b is formed as the step surface of the step 115.
