The Porsche Fuhrmann Engine (Type 547) was named after its inventor Ernst Fuhrmann, and built from 1953 to 1964. The Type 547, also called “drawer engine”, is an air-cooled four-cylinder boxer engine with four overhead camshafts that are powered by four vertical shafts. The crankcase, cylinder and cylinder heads of the engine are made of aluminum alloy. The special feature of this engine is its small size and low weight, which is achieved by the materials used and the clever construction.
