Combustion process of JP-8 and fossil Diesel fuel in a heavy duty diesel engine using two-color thermometry

► Emission of JP-8 and fossil Diesel fuel in terms of direct imaging and 2-color thermometry. ► Stronger and longer flame luminosity with fossil Diesel fuel. ► Higher decreasing rate of flame luminosity with JP-8. ► Locally high temperature region and lower level of KL factor with JP-8. ► Combustion analysis provides the reason for high NOx and low smoke of JP-8.
