It is significant to focus on the engine soot not only in controlling the engine exhaust emissions but also in improving the tribological performance of engine. The present project is based on the idea to control the abrasive wear behaviour of soot particles from biomass fuel by way of tribocatalytic process according to the detailed effect of soot particles from diesel and biomass fuel on the tribological performance of engine respectively. It will be characterized the relation among the biomass fuel soot, engine working conditions and tribological performance by studying the effects of the composition, structure, morphology and surface defects of soot particles on the catalytic effect and wear resistance and friction reduction. It is also studied the tribocatalysis reaction conditions of transform tribological function of soot particles during friction process, and the formation mechanism of antiwear and antifriction film derived from the soot particles from biomass fuel because of tribocatalysis induction as well. The mechanisms of friction and wear of soot particles are summarized at micro- and nano- scales by way of modern surface analysis methods. The wear model of soot particles from biomass fuel is also proposed. The present researches will develop the tribological theory of engine fuel and provide the theoretical and technical supports for the application of biomass fuel in the engine in the future.
