When intake air is compressed in the turbocharger, its temperature rises sharply. As a result, air density is reduced and the cylinders receive less fresh air than the system’s boost pressure prescribes. The risk of knock in spark-ignition engines also increases. These drawbacks are countered by charge-air intercooling, which passes the air leaving the turbocharger through a special cooler, increasing air intake as thermal load is reduced.
