Abstract
An arrangement for a supercharged combustion engine including a first compressor subjecting air to a first compression step, a second compressor subjecting the air to a second compression step, a first cooling system with a circulating coolant, a second cooling system with a circulating coolant which is at a lower temperature than the coolant in the first cooling system, a first charge air cooler applied to an air inlet line to the engine for cooling compressed air, the first cooler is located between the first compressor and the second compressor and is cooled by coolant from the second cooling system, a second charge air cooler applied to the air inlet line at a location downstream of the second compressor and is cooled by coolant from the first cooling system, and a third charge air cooler applied at a location downstream of the second charge air cooler and cooled by coolant from the second cooling system.
