Charge air cooler
(Intercooler)
Turbocharged engines employ a
turbo-compressor to force air into the engine
inlet manifold and a charge air cooler to cool
the compressed inlet air. The resulting increase
in air flow raises pressure in the intake
manifold and increases engine power over that
developed by A normally-aspirated engine.
The charge air cooler (which resembles a
radiator) is located between the
turbo-compressor and inlet manifold.
