Proposal: Enhancing SI Engine Efficiency via Turbocharging

This research proposal explores methods to enhance the efficiency of Spark Ignition (SI) engines, focusing on turbocharging systems for energy recovery from exhaust gas and electrical assistance during transient operations. The proposal outlines a methodology involving simulations using GT Suite cylinder modeling to analyze the impact of different turbocharger configurations (bigger turbine, bigger compressor, and standard turbocharger) on engine performance. It also addresses the potential for recovering exhaust energy through electrical machines coupled to the turbocharger shaft, operating in generator mode. The research includes a timeline, analysis of energy recovery potential, and consideration of safety issues, ultimately aiming to improve fuel consumption and engine efficiency while maintaining drivability.
