Abstract

508,996. Cylinders. MASCHINENFABRIK AUGSBURG-NURNBERG AKT.- GES. Nov. 24, No. 1938, No. 34239. Convention date, Nov. 24, 1937. [Class 7 (ii)] In a two-stroke engine cylinder, having superposed piston-controlled inlet and exhaust ports 3, 4, one or more exhaust ports 5 are increased in area by extending them downwards. The inlet ports below them are thus reduced in area, or they may be omitted.. The extended exhaust ports, which may be at the middle or ends of the row, may be trapezoidal in shape.
