The purpose of this project is to analyze a turbocharger system in a diesel engine. The turbocharger is used to increase engine power. The Chevrolet Suburban diesel engine comes with a stock turbocharger. In order to obtain more power from the engine, a new and larger turbocharger is being used. The new turbocharger is coupled to an air-water intercooling system to decrease the inlet air temperatures. This project analyzed the intercooling system and tested the final design in the vehicle. The results show that the cooling system components purchased are adequate for this system. The ideal turbocharger design would be smaller than the system purchased. The results discuss the actual sized heat exchanger needed for the ideal system.
