Abstract
Internal combustion engines remain an extreme contributor to global greenhouse gas emissions. With full electrification progressing, reductions in CO₂ emissions within a short time frame depends on improving the efficiency within existing engine technologies. Increasing the intake air for the engine is a practical way of reducing fuel consumption and emissions produced per unit of power.
A direct technology in improving thermal efficiency is superchargers, which increase the amount of air that enters the engine. With more air, fuel can burn more completely, allowing the engine to extract more energy from the same amount of fuel. This improvement in efficiency results in lower fuel usage and reduced CO₂ emissions.
This project investigates the use of a supercharger on a single-cylinder diesel engine test cell which is used for both emission and efficiency research. Within unboosted operation, the engine is limited by air intake, constraining both its performance and efficiency. The initial testing with an axial-flow compressor produced insufficient boost, which motivated the evaluation of alternative supercharger designs best suited for this application. With the selection of an appropriate system, this work will expand the engines operating range, thermal efficiency, and research focused on greenhouse gas reduction through efficient combustion.
