FIELD: internal combustion engines.
SUBSTANCE: invention can be used in internal combustion engines. A method for automated localization of leaky valves of the gas distribution mechanism (GDM) of a 4-stroke automobile gasoline or diesel 3÷12-cylinder internal combustion engine (ICE) of in-line, or V-shaped, or boxer types, longitudinal or transverse arrangement in the engine compartment of a car, of any design numbering of cylinders and any order of operation of cylinders includes pneumosmoke diagnostics of the combustion chamber of the tested cylinder, the piston of which is installed at the top dead center of the end of the compression stroke, and control over the exit of smoke from the control cylinders, the numbers of which determine the leakage of the inlet and outlet timing valves of the tested cylinder. On a personal computer in the operating system Windows-XP, or Windows-7, Windows-8, or Windows-10, a program is launched into which the type of location, the number of cylinders and the type of the diagnosed internal combustion engine are manually entered. They activate and, if necessary, edit the serial and design numbers of the cylinders and receive automatically calculated numbers of control cylinders and their visualization on the cylinder block diagram, which ensures the identification of control cylinders on the diagnosed internal combustion engine, quick and accurate localization of leaky timing valves of the tested cylinder, eliminating the need to combine intake and exhaust cavities tracts of banks of 8÷12-cylinder V-shaped and boxer internal combustion engines. The program calculates the serial numbers of cylinders according to the diagnostic model embedded in it, which are then converted into the corresponding design numbers of the cylinders.
EFFECT: ensuring the availability, speed and reliability of the localization of leaking timing valves.
