A centrifugal supercharger is a specialized type of supercharger that makes use of centrifugal force in order to increase the manifold air pressure, MAP. An increased MAP allows the engine to burn more fuel, which results in an increased power output.
First Merlin with two-speed supercharger, 1,145 hp (854 kW) in low gear at 5,250 feet (1,600 m), 1,010 hp (750 kW) in high gear at 17,750 feet (5,410 m). First of Rolls-Royce unitised " Power Plant " installation designs for this engine in 1937 [ 15 ] and used in Handley Page Halifax I , Vickers Wellington II , and Armstrong Whitworth Whitley V ...
Paxton Automotive is a United States–based manufacturer of superchargers for automotive use. The company is the major proponent of the centrifugal type supercharger. Early products were offered under the McCulloch name. Some Paxton superchargers have been factory fitted, but most units sold have been aftermarket installed.
An Eaton M62 Roots-type supercharger is visible at the front of this Ecotec LSJ engine in a 2006 Saturn Ion Red Line.. The Roots-type blower is simple and widely used. It can be more effective than alternative superchargers at developing positive intake manifold pressure (i.e., above atmospheric pressure) at low engine speeds, making it a popular choice for passenger automobile applications.
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.
Eventually there were around 350 companies that provided support to the project, including Rolls-Royce, which designed, manufactured and tested the two-stage centrifugal supercharger. The firm also developed the flame traps for the inlet manifold, used to prevent the highly compressed fuel/air mixture from exploding in a backfire.
