Abstract: As a renewable fuel, straight vegetable oils usage in diesel engine is a promising solution for energy crisis due to depletion of resources and increased environmental problems, however, with certain limitations. Research carried out specifically under China conditions and international research work on the usage of straight vegetable oils in the diesel engine is separately reviewed. The progress and deficiency of the current research are analyzed from the aspects of combustion, emission, fuel supply method and engine parts durability. The development trends of cylinder combustion analyzing, fuel supply and control system developing, engine durability improving and vegetable oil physicochemical properties researching are proposed. Finally, the future of straight vegetable oils usage in diesel engine in China is pointed out.

Key words: straight vegetable oils, diesel engine, combustion analyzing, engine durability
