Charge air cooler (Intercooler)Turbocharged engines employ a turbo-com-
pressor to force air into the engine inlet mani-
fold 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 devel-
oped by the normally-aspirated engine. The
charge air cooler (which resembles a radiator)
is located between the turbo-compressor and
inlet manifold.
Fuel systemThe engine is equipped with a multiport fuel
injection system.
