The Pratt & Whitney R-2800 Double Wasp is an American twin-row, 18-cylinder, air-cooled radial aircraft engine with a displacement of 2,800 cu in (46 L), and is part of the long-lived Wasp family of engines.
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 M-88 was designed to address the shortcomings of the Tumansky M-87.The improvements incorporated in the M-88 were a strengthened crankcase, crankshaft, connecting rods, waffle ribbing at the piston bottom and a two speed geared centrifugal supercharger.
The Pratt & Whitney R-1830 Twin Wasp is an American air-cooled radial aircraft engine. It displaces 1,830 cu in (30.0 L) and its bore and stroke are both 5.5 in (140 mm). The design traces its history to 1929 experiments at Pratt & Whitney on twin-row designs. Production began in 1932 and it was widely used during the 1930s.
The Zanzottera MZ 301 is a three-cylinder, in-line two-stroke, dual ignition aircraft engine designed for ultralight aircraft. [1] [2]The engine was originally designed and produced by Zanzottera Technologies of Italy, but the design was sold, along with the rest of the company's two-stroke ultralight aircraft engine line, to Compact Radial Engines of Surrey, British Columbia, Canada.

The Wright R-3350 Duplex-Cyclone is an American twin-row, supercharged, air-cooled, radial aircraft engine with 18 cylinders displacing nearly 3,350 cubic inches (54.9 L). Power ranged from 2,200 to 3,700 hp (1,640 to 2,760 kW), depending on model.
Utilizing the Wright R-3350 Duplex-Cyclone as a basis, Wright developed a 22-cylinder engine, using R-3350 cylinders arranged as a two-row radial engine with 11 cylinders per row instead of 9. [ 1 ] The air-cooled R-4090 was rated to deliver 3,000 hp (2,200 kW) at 2,800 rpm for take-off, from a total displacement of 4,092 cu in (67.06 L), with ...
The Centaurus had a cylinder swept volume of 3,272 cu in (53.6 L), nearly as much as the American 3,347.9 cu in (54.9 L) Wright R-3350 Duplex-Cyclone large radial, making the Centaurus one of the largest aircraft piston engines to enter production, while that of the Hercules was 2,363 cu in (38.7 L). The nearly 40 per cent higher capacity was ...
