NEW PETROL ENGINE

REVOLUTIONARY DESIGN. LONDON, November 25". Cheap high-powered cars are visualised by an English engineer, who has discovered new impulses in a singlecylinder petrol engine which he has designed, and he claims to be able to convert this into the equivalent of an engine with six ■ cylinders. The novelty of the discovery lies in the evolutionary design, which produces three explosions to each revolution of the engine, which is of the rotary type- The engine is practically vibration less owing to ■ the even distribution of the firing, and lubrication is said to be simplicity itself, while the accessibility of the parts and the great saying of weight per horse power are additional' advantages. The high speed of the engine creates a partial vacuum in the exhaust, and the back pressure is utilised and becomes an efficient supercharger for the carburetter. . • , • i This type of engine, it is claimed should be particularly adaptable for use in aeroplanes, while being equally suitable for road vehiees and stationary power units. Fitted to an aeroplane, the engine could be started without turning the propellor, which coun be rotated by operating a clutch. Hie inventor claims that bis single-cylinder engine is'equvale.it to a six-cylinder rotary engine, ,and it at least three times lighter in weight.
