Optimization of a positive displacement type supercharger using RSM

Air suction in a naturally aspirated engine is a crucial influencing parameter to dictate the specific fuel consumption and emissions. Also, to enhance the power rating of an existing engine, air availability is the first parameter to be looked into. For a multi-cylinder engine, a turbocharger can well address this issue. Typically, commencement of one cylinder exhaust stroke powers the turbo, which synchronises with the intake process of another cylinder. However, in a single or two-cylinder engine, the usage of turbocharger is not recommended, due to the lack of availability of continuous exhaust energy pulses. A supercharger solution comes handy in this regard for a single or two-cylinder engine. In this presentation, we explore the possibility of the usage of a positive displacement type supercharger, to enhance the air flow rate of a single cylinder, naturally aspirated, diesel engine for genset application.
