The turbocharger is a device which increases en-

gine output by sending a greater amount of air-fuel

mixture to the engine than under normal conditions.

Engine output depends upon the amount of the air-

fuel mixture ignited per unit of time. Therefore, to

increase engine output, the most effective method

is to send a greater amount of air-fuel mixture into

the cylinder.

In other words, by installing a special turbocharg-

er and providing more air-fuel mixture than usual,

engine output can be increased by increasing the

average combustion pressure without increasing

the engine speed.

Superchargers are either turbocharger type (us-

ing exhaust gas to turn the turbine) or supercharg-

er type (using the engine crankshaft etc., to

mechanically the pump, etc). For the Supra 7M-GTE

engine, the turbocharger type has been adopted.
