Abstract: The novel technology for wear analysis of the parts is developed to deal with the data of oil spectrum measurement in order to obtain the actual wear quantity of the parts on running. The materials wear experimental investigation is achieved to verify the validity of the theoretical model and numerical method. The initial experimentation of wear analysis for a vehicle engine is done. A powerful and efficient method to analyze and prospect the wear quantity of the parts for the research and experiment of the internal combustion engine is presented.

Key words: Internal combustion engine, Oil spectrum measurement, Wear
