0 a device which produces more power in an engine by forcing more air into the part of it in which fuel burns
It was late with front-wheel brakes, late with superchargers, late with self-starters, and late in every single thing.
Apart from large diesels with separate superchargers, two-stroke engines are generally piston-ported and use their crankcase beneath the piston for compression.
The chargers are a single supercharger that disengages after a specified rev-range, at which point charging of the air is handled by a single turbocharger.
He advocated the development of a number of aircraft innovations, including bombsights, sled-runner landing gear for winter operations, engine superchargers and aerial torpedoes.
This was accomplished by using loop scavenging ports for both intake and exhaust along with a mechanical blower (supercharger).
Turbochargers and superchargers are both engine-driven air compressors (exhaust-driven or mechanically-driven, respectively) and provide varying levels of "boost" according to engine rpm, load etc.
For 1949, the engine was further modified with dual overhead camshafts (though still two valves per cylinder) and a two-stage supercharger.
A central gear tower drove the overhead camshafts, superchargers and ancillaries.
