Combustion chamber, especially for internal combustion engine

摘要

In a direct fuel injection engine, comprising a piston 4 equipped with a plane surface 13 in which a combustion chamber 6 is made, a cylinder head 15 equipped with a lower plane surface 4 and an off-centred injector 5 making an acute angle with the surface 4, the combustion chamber 6 opens into the surface 13 of the piston with a V-shape widening in the direction of the axis of the piston and is delimited in its front surface by an arc whose diameter is greater than the diameter of the piston 1 and the combustion chamber 6 has its maximum depth H in the swirl zone which is furthest from the perimeter of the piston and its minimum depth C in the inlet zone closest to the perimeter of the piston. Application especially to internal fuel-combustion engines.
