Abstract

The engine has a finned cylinder (20) and a crankshaft (1) connected to a single piece piston (27) via a connecting rod (9). The end of the crankshaft has a spiral gear (2) which can be in plastic and which meshes with a gear on the vertical shaft (4) which drives the rotary valve (5) at half engine speed. The valve (5) is so shaped that it controls both inlet and exhaust flow. The other end of the crankshaft carries the flywheel (41) and a knurled wheel (44) which drives the road wheel by pressing on the tyre side wall (45). When used for other purposes the drive is transmitted by a V belt from the pulley (52).
