An electrically assisted turbocharger (EAT) is an arrangement where an electric motor assists the gas-driven turbocharger in providing forced induction, particular at times when exhaust gas flow is insufficient to produce the desired boost. [1] Some systems integrate the motor inside a turbocharger, while others use a separate electric ...
Superchargers are sometimes installed as original equipment on some vehicles manufactured today. Centrifugal supercharging creates an efficient, compact and intercooler friendly means to boost horsepower in both gasoline and diesel engines for a wide variety of watercraft, land craft and aircraft.
An electric supercharger is a specific type of supercharger for internal combustion engines that uses an electrically powered forced-air system that contains an electric motor to pressurize the intake air. By pressurizing the air available to the engine intake system, the air becomes more dense, and is matched with more fuel, producing the ...
Positive displacement superchargers deliver an almost constant level of boost pressure increase at all engine speeds, while dynamic superchargers cause the boost pressure to rise exponentially with engine speed (above a certain threshold). [4] Another family of supercharger, albeit rarely used, is the pressure wave supercharger.
A turbocharger for a car engine A supercharger (on top of a dark-grey inlet manifold) for a car engine. In an internal combustion engine, forced induction is where turbocharging or supercharging is used to increase the density of the intake air. Engines without forced induction are classified as naturally aspirated. [1]
In 2000, ProCharger managed an industry first by offering the first gear driven centrifugal supercharger with self-contained oiling. [18] It is credited with being the first to offer a supercharger system for Corvettes with LS engines, and in 2010 was the first to introduce supercharger systems for the Ford Raptor and 3.7L V6 Mustang.

The P1 has Formula 1 derived features such as the Instant Power Assist System (IPAS), which gives an instant boost in acceleration via the electric motor, a Drag Reduction System (DRS) which operates the car's rear wing, thereby increasing straight line speed, and a KERS. Both of these features (IPAS, DRS) are operated via two buttons on the ...
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 ...
