This term refers to the fact that turbochargers are a specific type of centrifugal supercharger, one that is driven by a turbine.
12.
A centrifugal supercharger has the advantage of generating less heat than other designs, especially pre-ignition that will destroy the engine.
13.
Several companies build centrifugal superchargers and also offer them as complete systems which can be easily installed by a mechanic or the auto enthusiast at home.
14.
It was tested in late 1938 and was a failure because of cracks in the master connecting rod and the geared centrifugal supercharger's impeller.
15.
The centrifugal supercharger is used in many applications including, but not limited to, automotive, truck, marine, aircraft, motorcycles and UTV s.
16.
An advantage of this design was that it was already well understood, having been implemented in centrifugal superchargers, then in widespread use on piston engines.
17.
Turbochargers were first used in production aircraft engines such as the Napier Lioness in the 1920s, although they were less common than engine-driven centrifugal superchargers.
18.
Beyond the use in aircraft which drove many improvements in centrifugal design, more widespread use of the centrifugal supercharger has been heavily focused on the automotive performance aftermarket.
19.
This was used primarily to drive a geared centrifugal supercharger, although it was also coupled to the crankshaft and gave an extra 15 to 35 percent fuel economy.
20.
Hooker's experience in the design of centrifugal superchargers, along with improved metals and combustion systems, put the engine back on track and it soon entered production.
