Abstract
Combustion chamber assembly of direct injection diesel engine comprising a cylinder head, a cylinder liner, an injection nozzle and a piston with a combustion chamber on its top. An air flow guide ring is provided in the combustion chamber assembly. The guide ring is arranged under and adjacent to the bottom surface of the cylinder and around the nozzle. The front end of the nozzle protrudes from the bottom of the guide ring. The peripheral surface of the guide ring acts as an air flow guide surface to lead the air squish. The air flow guide surface inclines in relation to the bottom surface of the cylinder head and its inclination angle is in the range of 30-70 degrees.
