In order to investigate the effect of heated temperature on fuel injection quantity for three kinds of fuels such as light oil, blends of rice bran oil with light oil and rice bran oil as a parameter of injection pump rack stroke, tests are performed by an injection pump tester at three kinds of cam shaft speed. In this study, also, the effects of rice bran oil properties on the fuel economy and exhaust emissions are experimentally examined by a single cylinder, four cycle, direct injection, water-cooled and agricultural diesel engine operating at several loads and speeds. The kinematic viscosity of rice bran oil is very high compared with light oil. Also. the oxygen is not included at all in light oil. while the oxygen contents of 10.7% are included in rice bran oil. The fuel injection timing is fixed to 22° BTDC regardless of fuel type, engine loads and speeds. Results show that fuel injection quantity increases as injection pump rack stroke and cam shaft speed are elevated at the same conditions, and as heated temperature is elevated with the exception of light oil. It is also found that brake specific fuel consumption rate and NO<SUB>x</SUB> emissions increase, while soot emissions decrease as the blend rate of rice bran oil is enriched. Thus we can conclude that the differences of chemical and physical properties control the major parameters of combustion process which affect the fuel economy and exhaust emissions of diesel engines using a rice bran oil as fuels.
