A mechanically driven supercharger offers exceptional response and low-rpm performance, as it does not rely on pressurization of the exhaust manifold (assuming that it is a positive-displacement design, such as a Roots-type or twin-screw, as opposed to a centrifugal supercharger, which does not provide substantial boost in the lower rpm range), but is less efficient than a turbocharger due to ...

Honda's CVCC engine, released in the early 1970s models of Civic, then Accord and City later in the decade, is a form of stratified charge engine that had wide market acceptance for considerable time. The CVCC system had conventional inlet and exhaust valves and a third, supplementary, inlet valve that charged an area around the spark plug.
The Stellantis Hurricane GME-T6 engine is a twin-turbocharged straight-six engine produced by Stellantis since November 2021 at their plant in Saltillo, Mexico, and announced publicly in March 2022. It debuted with two versions, one of standard output (SO) and one of high output (HO), both featuring a start-stop system but designed for more ...
The Pratt & Whitney Canada PW800 is a series of turbofan engines in the 10,000–20,000 lbf (44–89 kN) thrust class, manufactured by Pratt & Whitney Canada.Intended for the regional jet and business jet market, the gear-less PW800 shares a common core with the larger, geared PW1000G.
In an internal combustion engine, twin-turbo is a layout in which two turbochargers are used to compress the intake fuel/air mixture (or intake air, in the case of a direct-injection engine). The most common layout features two identical or mirrored turbochargers in parallel, each processing half of a V engine 's produced exhaust through ...

With Pratt & Whitney starting development of their own 2,800 in 3 (46 L) displacement 18-cylinder, twin-row radial as the R-2800 Double Wasp in 1937, Wright's first R-3350 prototype engines with a 3,350 in 3 (54.9 L) displacement were run in May of the same year. Development was slow, due to the complexity, and the R-2600 receiving development ...
