Project Abstract

The vast majority of the energy combusted in an internal combustion engine is lost as heat to the environment.  Finding a use for this lost heat represents huge potential for efficiency gains in automobiles. The objective of our senior design project is to effectively capture and utilize this waste heat in order to increase the fuel efficiency of an automobile.  Through the engineering design process, our team arrived at a solution which involves the use of a Stirling engine integrated into the exhaust system of a car.  Our system seeks to take this waste heat and convert it into usable electrical energy, which can then be reused in the automobile.
