The article analyzes the effective methods and techniques of diagnosing gasoline internal combustion engines, highlighted the most promising ones. Of the existing seven modern methods considered: thermal control, computer diagnostics, analysis of the composition and quantity of waste gases, technical endoskopirovanie, gauging the compression, the analysis of chemical elements and vibroacoustic. On the presented methods compiled a comparative table on a number of parameters: the cost of ongoing services, the cost of equipment, the length of the diagnostic information content requirements for personnel. The advantages and disadvantages of the methods considered in the parameters. It concludes that characterize the main directions of development of systems of technical diagnostics of internal combustion engines.
