Junkers L88

Aircraft Engines

The Junkers L88 was the company's first geared V12 engine, appearing around 1930 and made by combining two six-cylinder L8s into a 60 degree V12 on a common crankshaft, in the same way the L55 had been made from two L5s. It kept the water cooling and the twin pairs of valves per cylinder of the L5, with a choice of reduction gear ratios from 2.47 to 1 down to 1.44 to 1, and an exhaust-driven supercharger added in 1932 gave the L88a. It produced 675 hp in cruise at 1,870 rpm and 788 hp at take-off from 45.8 litres. Only a few were built. They powered the Ju 49 high altitude research aircraft, the G 38 airliner and the Japanese-built Mitsubishi Ki-20 bomber, the last two later switching to Jumo 204 diesels.
