2005 Saturn Ion Red Line
several firsts for Saturn. Besides the Eaton helical Roots supercharger, theres an air-to-water intercooler to reduce the temperature of air entering the engine. Cooler air compliments the performance of the supercharger. Also, electronic throttle control replaces the cable between the gas pedal and motor

also uses the air-to-water crossflow intercooler tucked in the engine's V. It lowers the temperature of intake air, making it denser, further boosting power. The Mercedes station wagon, like all E-Class vehicles this year, will use electronic braking, making it the first large-scale use

, the turbo wastegate and intercooler pop-off valve. This will cut pilot workload considerably. The Bombardier engines have several other innovative features, including their V configuration and allaluminum engine blocks. Earlier " allaluminum" blocks needed steel cylinder liners, which added weight

to the inlet side of the intercoolers at a temperature as high as 200°C with a pressure of up to 3 bars. Conventional turbo systems use aluminum air ducts that are either cast or hydro-formed. Silicone rubber with textile inlays is another option. But air ducts made from these materials are expensive

Aircraft Liquid Cooling
, PAO is sometimes used in intercooler applications to cool gaseous nitrogen (GN2) for inerting fuel tanks to reduce fire hazards. One way that engineers can save space and minimize weight is to route fluids currently in use on the aircraft through the liquid cooling loop. For example, fuel may be used
