V20 engine
Encyclopedia : V : V2 : V20 : V20 engine
A V20 engine is a V engine with 20 cylinders.
Engines of this number of cylinders are not common, but this configuration was used in some large diesel engines. For example, the 1960s vintage General Motors Electro-Motive Division EMD SD45 railroad locomotive was fitted with a 20-cylinder EMD 645E3 engine.
The engine name is based on the displacement of each cylinder in cubic inches. In this case 645 inch³ (10.6 L) for each of 20 cylinders - a total of 211 L. Power output is 3,600 horsepower (2.7 MW).
V20 diesel engines have also been used in marine applications: Mercedes-Benz has produced one such engine.
