Abstract

475,179. Oil engines. BUCHI, A. Feb. 7, 1936, No. 3758. Void. Convention date, Feb. 9, 1935. [Class 7 (iii)] In a four - stroke engine in which there is overlap of exhaust and admission periods, the air charge is whirled in a heart or pear shaped combustion chamber 6 by baffles 8 on either the piston face or the cylinder head. The baffles are adjacent both the inlet and the exhaust valves.
