Evaluation and Comparison of Performance, Combustion Characteristics, NOx and Particle Emission of Gasoline, JP-8 and Diesel Fuel in a Military Heavy Duty 38 Liters CIDI Engine Applying EGR

Global emission, rapid exhaustion of oil reserves and stern emissions protocols force us to seek alternative fuels for heavy duty diesel engines. Assessing the influence of Gasoline and JP-8 fuels on the engine performance and gaseous emissions of heavy-duty diesel engines is essential. Multi-fuel strategy program is required for the both, combat vehicles and highways commercial vehicles to optimised the fuel availability. With the Gasoline and JP-8 fueled diesel engine, penalties of fuel economy are well known. Experimental evaluation has confirmed that Gasoline and JP-8 fuels have great potential in reducing NOx emissions. Present study focuses on the effect of engine performance and emission by using Gasoline and JP-8 fuels in heavy duty military engine. NOx and nanoparticles emissions reduction were assessed. EGR is a better technique to reduce NOx. All these parameters were compared for diesel, Gasoline and JP-8 fuels in a 582-kW, 12-cylinder, military heavy- duty diesel engine with 5% EGR at different engine speeds with load conditions between 20% and 100%. A slight deterioration in engine performance was observed for Gasoline and JP-8 fuels vis-à-vis diesel. NOx emission was lowered by 30-43% along with nanoparticle emission when engine was operated with Gasoline and JP-8 fuels.
