Packard DR-980 diesel radial aircraft engine A Nordberg Manufacturing Company two-stroke diesel radial engine for power generation and pump drive purposes. While most radial engines have been produced for gasoline, there have been diesel radial engines. Two major advantages favour diesel engines — lower fuel consumption and reduced fire risk.

Mechanics nicknamed them Parts Recovery Turbines, since the increased exhaust heat meant a return to the engine destroying exhaust valves. The fuel burn for the PRT-equipped aircraft was nearly the same as the older Pratt and Whitney R-2800, while producing more useful power. [5] Effective 15 October 1957 a DA-3/DA-4 engine cost $88,200. [6]
The Vedeneyev M14P is a Russian nine-cylinder, four-stroke, air-cooled, petrol-powered radial engine. Producing 360 hp (268 kW), its design dates from the 1940s (Kotelnikov 2005), and is itself a development of the Ivchenko AI-14 engine. The engine has been used extensively by the Yakovlev and Sukhoi Design Bureaus.
The Pratt & Whitney R-4360 Wasp Major is an American 28-cylinder four-row radial piston aircraft engine designed and built during World War II.At 4,362.5 cu in (71.5 L), it is the largest-displacement aviation piston engine to be mass-produced in the United States, and at 4,300 hp (3,200 kW) the most powerful.
The production run of 173,618 R-1830 examples [1] makes it the most-produced aviation engine in history. A further developed version, the R-2000 , was produced starting in 1942. The R-2000 was "bored-out" to 5.75 in (146 mm) and had a number of other minor changes to improve fuel economy and allow it to run at higher power ratings on lower ...
The R-755 was first run in 1933 and was still in production in the 1970s. With a bore and stroke of 5.25 in × 5 in (133 mm × 127 mm) the displacement was 757 cu in (12.4 L), power ranged from 200 hp to 350 hp (150 kW - 260 kW).
It was the Pratt & Whitney aircraft company's first engine, and the first of the famed Wasp series. It was a single-row, nine- cylinder , air-cooled , radial design, and displaced 1,344 cubic inches (22 L); bore and stroke were both 5.75 in (146 mm).
