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 ...
Using this system, the famous BMW engine used in the Focke-Wulf Fw 190 would be known as the 9-801 (Piston(9)-BMW(8)Number(01)). However, this system was not widely used, even within the RLM, and a common name consisting of the manufacturer's name (often abbreviated) followed by the model number was much more common.
Much like the Charomskiy ACh-30, the M-40 was a development of the experimental AN-1RTK turbo-supercharged diesel engine that had begun development in the early 1930s.It dropped its predecessor's supercharger, but added another two E-88 turbochargers and two intercoolers.
The company's first major product was an oil cooler for military aircraft. Garrett designed and produced oil coolers for the Douglas DB-7. [9] Boeing's B-17 bombers, credited with substantially tipping the air war in America's and Great Britain's favor over Europe and the Pacific, were outfitted with Garrett intercoolers, as was the B-25.

In 1944 a series of newer engines was introduced, allowing the engine to run on the 100 octane "C3" fuel and optionally including fittings for various optional power-boosting agent dispensing systems, such as the MW50 methanol-water injection system, and GM-1 nitrous oxide injection system. The DB 605AM, running initially on C3 and MW-50, saw ...
Although its mid-engine placement was innovative, the P-39 design was handicapped by the absence of an efficient turbo-supercharger, preventing it from performing high-altitude work. For this reason it was rejected by the RAF for use over western Europe but adopted by the USSR, where most air combat took place at medium and lower altitudes.

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.
