Internal combustion engines are the major source of air pollution. Especially, compression ignition engines in today’s industrial and automotive general engines contribute the most to NO_x, CO, particulate emission and soot, and it is recognized that these emissions have a detrimental effect on human and earth environment. So an improvement of spray combustion for diesel engines is of urgent necessity. From this point, experiments have been carried out to obtain the essential data on spray combustion influenced by blend fuel with emulsion in small diesel engine. The main conclusion are as follows: 1) The maximum burning pressure of blend oil with emulsion is smaller than that of light oil; 2) NO_x emission of the blend oil with emulsion is smaller than that of light oil.
