In a cycle internal combustion engine, a mask wall is provided on the inner wall surface of the cylinder head to close the exhaust valve side portion of the opening formed between the intake valve peripheral edge and the valve seat during the full opening period of the intake valve, and a mask wall is provided on the cylinder head side. A fuel injection valve is disposed on the peripheral edge of the inner wall surface of the head, and the top surface of the piston is provided with a raised part on the exhaust valve side and a recessed part continuous to the piston peripheral part on the piston center side of the raised part. The peripheral edge of the piston is connected to the inner wall of the cylinder on the intake valve side by an inclined surface having an inclination that smoothly continues, and the protrusion and the recess are connected to the inner wall of the cylinder on the exhaust valve side by an inclined surface having an inclination that continues smoothly. A combustion chamber for a two-stroke internal combustion engine, in which the peripheral edge side of the piston of the raised portion is formed so as to face an inner wall surface of an exhaust valve side cylinder head with a slight gap therebetween when the piston is located at the top dead center.
