Cavitation in engine fuel pumps has a significant impact on the safety and life of the engine. Through a comprehensive overview of domestic and international research results on cavitation in engine fuel pumps, we have systematically summarized the reasons for the formation of cavitation in fuel pumps, the factors affecting it, the research methods and the current status of the development of cavitation, and introduced the two major factors affecting the generation and development of internal cavitation in fluid machinery, namely, the geometrical form of the objects in which cavitation occurs and physical factors (such as pressure, temperature, etc.). And for the research and observation of the cavitation phenomenon in this component of the method for organization and division, and gives the study of cavitation phenomenon in the fluid machinery and reduce the impact of the cavitation of the new program, for the optimization of the engine fuel pump to provide a direction.
