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 2021-01-1183

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.
