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 ...
The LM6000 provides 54,610 shp (40,720 kW) from either end of the low-pressure rotor system, which rotates at 3,600 rpm.This twin spool design with the low pressure turbine operating at 60 Hz, the dominant electrical frequency in North America, eliminates the need for a conventional power turbine.
Nissan VQ engine, Nissan RB engine The VR is a series of twin-turbo DOHC V6 automobile engines from Nissan with displacements of 3.0, 3.5, and 3.8 L. An evolution of the widely successful VQ series , it also draws on developments from the VRH , JGTC , and Nissan R390 GT1 Le Mans racing engines.
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 ...
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 ...
In addition to 3,000-shp output, the targets for AATE were a 25% reduction in fuel consumption (less than 0.347 lb/(hp⋅h), 211 g/kWh), a 65% improvement in power to weight (more than 6.5 hp/lb, 10.7 kW/kg), a 20% improvement in design life (more than 6000 hours and 15000 cycles), a 35% reduction in production (less than $650k per engine) and maintenance cost, and a 15% reduction in product ...

The process of evolving the engine was gradual and continuous; by 2006 almost all the 1959-specification engine components had been upgraded, so that the 2020 twin-turbo 6.75-litre engine produced over 150% more motive power and torque than at the beginning of its life, had 40% better fuel economy, and produced 99.5% less exhaust emission.
