Abstract
A crank chamber in a multicylinder-engine is divided by division walls into a plurality of spaces each of which contains one set of cranks fixed to a crankshaft, and in which varying air pressure is developed. The air under such pressure flows into a pressure chamber of an air-pump, as power source to drive the pump; suitably compressed air is produced in a pump chest of this air-pump. This air can be supplied to an exhaust gas passage for recombustion of incompletely oxidized combustive gas in the exhaust gas.
