Abstract
In this study, the effects of injection timings on engine combustion, performance, and emission characteristics were investigated experimentally using a four-cylinder diesel engine equipped with an endoscopic visualization system. The experiments were conducted at constant speed (1500 rpm) with different start of injection timings and two loads (10 and 25% load, respectively). Premixed combustion was found from the heat release rate and combustion images with advanced injection. Additionally, larger area of luminous flames was obtained for retarded injection timing and higher engine load. It was also found that the area of soot distribution and flame temperature distribution decreased for advanced injection timing. NO x emission increased for advanced injection, however, an opposite trend was observed for lower load.
