Near the end of WWII, the system was changed to use gasoline direct injection which improved reliability. After the war the engine was redesigned and became popular for large aircraft, notably the Lockheed Constellation and Douglas DC-7. Following the war, the Turbo-Compound [4] system was developed to deliver better fuel efficiency.
For example: the -18W was a "C" series engine, built from 1945, whereas the -21 was a "B" series engine, built from 1943. Until 1940 the armed forces adhered strictly to the convention that engines built for the Army Air Forces used engine model numbers with odd numeric suffixes (e.g.: -5), while those built for the US Navy used even (e.g.: -8).
The USCG Hamilton-class cutters use the 38 8-1/8 engine in a CODOG arrangement, where the diesel engine provides cruise propulsion, and a gas-turbine provides propulsion where high speeds are required. The Fairbanks Morse Opposed Piston engine is also used as a stationary power generator engine, both in primary and standby duties. [13]
The Allison V-1710 aircraft engine designed and produced by the Allison Engine Company was the only US-developed V-12 liquid-cooled engine to see service during World War II. Versions with a turbocharger gave excellent performance at high altitude in the twin-engined Lockheed P-38 Lightning, and turbo-superchargers were fitted to experimental ...
A turbocharger does not place a direct mechanical load on the engine, although turbochargers place exhaust back pressure on engines, increasing pumping losses. [ 52 ] Supercharged engines are common in applications where throttle response is a key concern, and supercharged engines are less likely to heat soak the intake air.

R-2600-14 - 1,700 hp (1,268 kW)- One of the engines which powered Grumman's prototype F6Fs, the XF6F-1 (the two-stage supercharged R-2600-10 was also tested in the XF6F-1). Grumman was not happy with the performance, which led to the 2,000 hp Pratt & Whitney R-2800 engine replacing the R-2600 on F6F production models.
It was designed to test the Whittle jet engine in flight, and led to the development of the Gloster Meteor. [10] The first two operational turbojet aircraft, the Messerschmitt Me 262 and then the Gloster Meteor, entered service in 1944, towards the end of World War II, the Me 262 in April and the Gloster Meteor in July. Only about 15 Meteor saw ...
