A straight-9 engine is a straight engine with nine cylinders. Straight-9 engines are usually diesel engines used for ship propulsion. Rolls-Royce Marine Engines (formerly Bergen Diesel), Pielstick and Wärtsilä (formerly Wichmann) have made this type of engines. Straight-9 engines in current production include models in the Rolls-Royce Bergen B, C and K series, and the Wärtsilä RT-flex60C-B, RT-flex82C, RTA84T-D, RTA84C, RTA96C, 20, 26, 32, Wasa32LN, 38, 46 and 46F series. The 9 cylinder versions of these engines develop between 1620 and 51480 Kw (2170 - 69040 hp).
