A Cummins aftercooler is a device that cools the compressed air produced by a Cummins engine turbocharger or supercharger. This is important because when air is compressed, its temperature rises, reducing its density and oxygen content, negatively affecting engine performance.Compressed air passes t

What is a charge air cooler?Internal combustion engines, particularly turbocharged or supercharged engines, employ a charge air cooler (also known as an intercooler) to cool compressed air before it enters the combustion chamber. The charge air cooler lowers the compressed air's temperature by relea
