All WEP methods result in greater-than-usual stresses on the engine, and correspond to a reduced engine lifetime. For some airplanes, such as the P-51D, use of WEP required that the engine be inspected for damage before returning to the air. [4] 5 hours' total use of WEP on the P-51D required a complete tear-down inspection of the engine. [4]
The A-40-4 introduced an increase in power to 40 hp (30 kW). The engine later inspired the A-50 and subsequent engines. [1] [2] [4] The A40 featured single ignition until the A-40-5 version, which introduced dual ignition. All engines in this family have a 5.2:1 compression ratio and were designed to run on fuel with a minimum octane rating of ...
Gasoline engines up to WWII were often valve in block design (L-head), during the war more overhead valve (ohv) engines were used, and after the war all new engines (except 1 F-head and 1 Overhead camshaft (ohc)) have been ohv. All diesel engines have ohv, they can be naturally aspired, supercharged (SC), or turbocharged (TC).

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 ...
The 2si 460 is a family of in-line twin-cylinder, two-stroke, single ignition, aircraft engines that were designed for ultralight aircraft. [1]The basic engine was originally designed and produced by ILO-Motorenwerke of Germany and was later acquired by the AMW Cuyuna Engine Company of Beaufort, South Carolina and marketed under the Cuyuna brand name.
The Rotax 447 is a development of the Rotax 377, increasing the power output from 26 kW (35 hp) to 29.5 kW (40 hp) by increasing the cylinder bore from 62 mm to 67.5 mm and the maximum rpm from 6500 to 6800. [2] The modern 447 has a single breakerless, magneto capacitor-discharge ignition (CDI) system.
