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 form.
CONSTITUTION: A lip part 3 is provided on the peripheral edge of inlet part of the combustion chamber 10 so that the lip part extends toward the center. The outer diameter D (mm)of a piston 8, the length d (mm) of the lip part and the angle β° of collision of injected fuel against the side wall of the combustion chamber 10 are related to one another as d=(0.002W0.02)D and 2d+9.5<β<2d+135. The collision angle β affects the quantity of the blow-up and the quantity of fuel blown into a quench zone S' by the reverse skish flow V. The length d and the angle β are determined depending on data. The combustion blow-up as caused in conventional open combustion chamber is prevented. The combustion efficiency is improved. The quantity of black smoke and NOx is reduced.
