Abstract
The improvement in a combustion engine of the conventional type includes air inlet means disposed in the vicinity of an end of the cylinder facing away from the spark plug for receiving air into the cylinder, and a first plate attached to the cylinder in the vicinity of that end. The first plate is attached to the cylinder and formed with first and second openings for the cylinder and air to pass therethrough, respectively. A second plate, which fits into the cylinder is attached to the piston in the vicinity of an end portion of the latter facing the spark plug, and is formed with a third opening for passing air therethrough. Piston-and cylinder-rings slide between the first plate and the cylinder end, and between the second plate and the end portion of the piston, respectively, for a timed control of the air received into the cylinder through the air inlet means.
