Abstract

PURPOSE: To prevent the blow-up, improve the combustion efficiency and reduce the quantity of black smoke and NOx, by making a combustion chamber in an appropriate from.
CONSTITUTION: A lip part 13 is provided on the peripheral edge of inlet part of the combustion chamber so that the lip part extends toward the center. The outer diameter D (mm) of a pistion 8, the length d (mm) of the lip part and the vertical angle α° of a conical projection 14 provided on the bottom of the cumbustion chamber are related to one another as d=(0.002W0.02)D and 2000d/D+40<α<1500d/ D+120. A vortrical flow U is caused and maintained by the projection 14. When the piston 8 is in the expansion process, the reverse skish flow V is surely weakened. Therefore, the amount of black smoke is reduced. The length d and the angle α° are determined depending on data.
