Abstract
PURPOSE: To prevent the thermal damage and the production of graphite, by making a combustion chamber in an appropriate form.
CONSTITUTION: A lip part 13 is provided on the peripheral edge of inlet part of the combustion chamber 10 so that the lip part 13 extends toward the center. The outer diameter D (mm) of a piston 8, the length d (mm) of the lip part 13 and the tilt angle θ° of side wall of a recess 9 are related to one another as d=(0.002W 0.02)D and 0.5d+1<θ<3.0d+10. The tilt angle θ affects the reverse skish flow F and the revolving flow U. When the piston 8 preforms the expansion movement, the reverse skish flow V takes place. When the reverse skish flow V is weakened, the combustion in a quench zone is reduced and the production of graphite is prevented. When the revolving flow U is maintained well, the reverse skish flow V and the production of graphite are reduced.
