DIRECT INJECTION TYPE DIESEL ENGINE

PURPOSE:To restrict both exhaust of NOx and smoke generation of a direct injection type diesel engine formed with a shallow-dish-like cavity on the top surface of its piston. CONSTITUTION:The outer peripheral wall 14 of a cavity 13 is formed in a shape expanding by 130-140 degrees to the top surface...

Zusammenfassung:	PURPOSE:To restrict both exhaust of NOx and smoke generation of a direct injection type diesel engine formed with a shallow-dish-like cavity on the top surface of its piston. CONSTITUTION:The outer peripheral wall 14 of a cavity 13 is formed in a shape expanding by 130-140 degrees to the top surface of a piston 11. Next, an angle in the vertical surface direction of mutual atomization injected to the cavity 13 is set to 130-145 degrees. Further, the dimension d of the aperture portion of the cavity 13 is not less than 0.85D for the diameter D of the top surface of the piston.
