    • A combustion device for an internal combustion engine which includes a cylinder, a head closing one end of the cylinder, and a piston reciprocable in the cylinder. The head and piston have stepped portions adapted to interfit as the piston approaches the head so as to define a compression chamber and a combustion chamber of greater volume than the compression chamber, for receiving a fuel charge, and a restricted passage between the combustion chamber and the compression chamber. The head and piston are shaped and the device is otherwise provided with structure so that as the piston approaches dead center, a portion of the charge compressed in the compression chamber combusts spreading combustion gases and flame through the restricted passage so as to immediately thereafter cause swirling of, and ignite the portion of the charge in, the gases in the combustion chamber.

    • A combustion promoter for an internal combustion engine comprising a cylinder having a combustion chamber therein, a main piston movable within the cylinder, a sub-piston mounted on an inner wall of the main piston, and a sub-cylinder surrounding the projecting portion of the sub-piston and defining a sub-cylinder chamber. The sub-piston is driven in relation to the stroke of the main piston toward the combustion chamber until the main piston has reached a position in the vicinity of top dead center of a compression stroke. Gas in the combustion chamber is then introduced into the sub-cylinder chamber where it is stored. The sub-piston is next moved rapidly away from the combustion chamber to eject the gas stored in the sub-cylinder chamber into the combustion chamber, thereby promoting combustion of the gas.
