What is the function of intercooling?

What is an intercooler and what does it do? The intercoolers (Charge Air Coolers) are designed to reduce fuel consumption while increasing the engine power and efficiency. The intercooler's task is to reduce the temperature of the inlet gas and thus densify the air required which optimises the combustion.

How does an air compressor intercooler work?

An air-to-air intercooler works by passing the compressed air through a network of small tubes past a number of cooling fins. The hot compressed air passing through the intercoolers tubes then transfers its heat into these cooling fins, which in turn are kept cool by the flow of ambient air around them.
