Supercharged combustion engine e.g. petrol engine, for car, has compressed air flow cooling loop and coolant loop provided in connection with each other such that coolant liquid flow passes from one loop to another loop

摘要

The engine has a turbocompressor (20) for producing a compressed air flow output (27), and a compressed air flow cooling loop or supercharging cooler (60) is arranged for circulation of cooling liquid or water. A central stage (24) is provided for the turbocompressor. A coolant loop such as control loop (81) is arranged for circulation of the cooling liquid. The compressed air flow cooling loop and the coolant loop are provided in connection with each other such that a coolant liquid flow passes from one loop to another loop.
