事を特徴とする２サイクルエンジンの燃焼室。The top dead center side end surface 3 of the combustion chamber 2 of the two-cycle engine 1 is formed into a partially concave spherical shape, and the outer circumferential portion 14b of the top surface of the piston 14 is formed into an annular partially convex spherical shape. A closer portion 14a is formed on the large recessed surface 20,
When the piston 14 is at the top dead center, the outer circumferential portion 14b of the piston top surface 22 is close to the top dead center side end surface 3 of the combustion chamber 2, and a squish area 24 is created between the two. The discharge terminal 6 of the ignition plug 5 is located in the center of the top dead center side end surface 3 of the chamber 2, and the mixture flow receiving surface 25 covering one side of the outer peripheral space of the discharge terminal 6 is connected to the combustion chamber 2.
A combustion chamber for a two-stroke engine, characterized in that it is formed by protruding into the combustion chamber 2 side from an end face 3 on the top dead center side.
