Increase in power over the whole speed range, low fuel consumption,
improved engine efficiency, reduction of emission
values, less thermal pressure on the engine - there are numerous
reasons to cool the combustion air of supercharged engines with
intercoolers. A basic distinction must be made between two
types of cooling. Direct cooling, where an intercooler is installed
in the vehicle front-end area and is cooled by
environmental air (wind blast) or indirect cooling, where coolant
flows through the intercooler and discharges the heat to the environmental
air.
