Automotive starting systems require substantial amounts of mechanical energy in a short period of time. Lead-acid batteries have typically been used with a motor to provide that energy. Springs have been identified as an alternative energy storage medium and are well suited to engine-starting applications due to a long service life and the ability to rapidly deliver substantial mechanical power. This research aims to explore the feasibility and potential benefit of a spring-based engine-starting system. A dynamic engine model was first developed by collecting data from a 600cc 4 cylinder engine and electric starting system. The model was used to simulate the engine response for several spring-based starting system designs. Each system was then evaluated on the basis of weight, volume, engine speed produced, and ability to crank the engine for several seconds.
