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