Abstract :Ignition and flame propagation phenomenon of diesel fuel combustion was investigated in an optical single cylinder engine. Conventional non-premixed diesel combustion and partially premixed combustion types were investigated. Experiments were performed on an optical single cylinder, heavy duty, four-stroke compression ignition engine with a quartz elongated piston bowl and 45° mirror was used for visualization as a measurement technique. . Self-ignition, flame propagation, heat rejection and effects on number of pilot injections on combustion visualization are investigated. In conventional diesel with closed and far pilot and partially premixed charge compression ignition insert ignore into journalissuearticles values(PCCI); tests were performed.
