The main task of an advanced engine cooling system is to control the temperature of the engine, the components and the media involved to an optimum level. The thermal interactions inside the engine are complex and call for accurate thermal management design. In future cars, the mass flows of the participating media can be proportioned by electronically controllable coolant pumps, control valves, fans, and radiator shutters in order to achieve optimum temperatures for engine cabin and components. The efficiency of the respective measures has been verified in tests and the influence on the fuel consumption has been determined. By combining various different measures fuel consumption can be reduced by about 5 % as can exhaust gas and acoustic emissions to a certain extent. The warm-up period can be shortened significantly, thus contributing to a higher level of comfort in the passenger compartment.
