Experimental Evaluation of Energy and Exergy of Hydrogen, CNG and Gasoline Fuelled High-Speed Spark Ignition Engine

The maximum power is recorded with Gasoline than CNG and Hydrogen fuel.

The maximum exergy and energy efficiency is with Hydrogen, followed by CNG and then Gasoline.

Hydrogen fuel has a maximum potential to convert into energy.

The maximum energy destruction of 48.7kW for gasoline fuel at 3000 rpm and followed by CNG and hydrogen.

The maximum entropy generation of 85.5 W/K with Gasoline and 60.72 W/K and 29.39W/K for CNG and hydrogen engine respectively at 10000 rpm. The entropy generation rate increase with engine speed.

The highest rate of heat release is from hydrogen fuel, followed by Gasoline and CNG.
