Combustion process with JP-8 and diesel was analyzed in an optically-accessible single-cylinder heavy-duty diesel engine equipped with a high pressure common-rail injection system. Direct imaging and two-color thermometry were applied to verify the emission trend for both fuels. The combustion process was characterized by means of image analysis focusing on the luminosity. The results from the two-color thermometry were analyzed by flame temperature and KL factor distribution. From the combustion process analysis of direct imaging, it was verified that JP-8 had a longer ignition delay compared to diesel, while flame was vanished more rapidly. Analysis of flame luminosity intensity showed that diesel combustion had higher intensity and lasted for longer duration. Two-color thermometry results showed that higher temperature region was distributed more with JP-8 combustion, which means that more NOx was formed with JP-8 combustion. Also, relatively homogeneous and low level of KL factor distribution was shown with JP-8 combustion, which implied that JP-8 combustion produced less smoke emission.
