Abstract: Soybean oil based fatty acid methyl ester (FAME) is produced and blended with diesel fuel at 25% volumetric ratio. Besides, pure hydrogen (H2) and compressed natural gas (CNG) mixture named HCNG fuel is used with 20 litres per minute (L/min) volumetric flow rates. The amount of liquid fuel injected into the cylinders is reduced by 30% via fuel pump plunger pin without structural changes on the diesel engine. Instead of the reduced liquid fuel, 20% hydrogen with 80% CNG gaseous fuel mixture (by volumes) are supplied by using mixing chamber before intake manifold of the test engine. Brake power, brake torque and brake specific fuel consumption and also thermal efficiencies are presented under performance outputs subsection. Results were compared and discussed. Additionally, exergy analysis of control volume has been performed. Using HCNG fuel enriched biodiesel effects on performance and energy efficiency are examined. Therefore comparison between diesel operation and alternative fuel usage is evaluated.
