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 com- pressed inlet air. The resulting increase in air flow raises pressure in the intake manifold and increases engine power over that developed by the normally-aspirated engine. The charge air cooler (which resembles a radiator) is located between the turbo-compressor and inlet manifold. 272
