Spray, Combustion, and Air Pollutant Characteristics of JP-5 for Naval Aircraft from Experimental Single-Cylinder CRDI Diesel Engine

This study was performed to analyze the spray, combustion, and air pollutant characteristic of JP-5 fuel for naval aircraft in a spray visualization system single-cylinder CRDI diesel engine that can be visualized. The analysis results were compared with DF. tip penetration showed diminished as developed. had highest ROHR ROPR regardless injection timings. physicochemical characteristics JP-5, such its excellent vaporization low cetane number, analyzed prolong ignition delay. Overall, longer combustion period lower heat loss DF raised torque IMEP. higher O2 CO2 levels than fuel. CO emission level increased timing advanced two test fuels, emitted from fuel, which has turned out lower. NOx also reduced retarded, but it discharged at due large release. images process flame luminosity is stronger, delay shorter, JP-5.
