Many studies of diesel engine operation fueled by vegetable oils have been carried out because the vegetable oils are renewable and offer potential reductions on carbon dioxide emissions. To improve the oil characteristics this paper investigates gas oil blended rapeseed oil as diesel substitutes. Initially the spray characteristics such as spray angle and penetration were examined using spray images whose were taken photos with single injection into air at high pressure and room temperature (1.57MPa and 298K). The performance and emissions of two DI diesel engines with different chamber types were also examined. As a result, the equal proportions of rapeseed oil and gas oil showed good spray, engine performance, and emission characteristics as well as gas oil operation.
