Abstract

Statistical analysis shows that the fuel supply system of gasoline internal combustion engines takes the leading place in the number of failures. In particular, the failure of electric gasoline pumps is the first in line. The reliability of modern diagnostic methods in detecting EGP failures is at an unacceptably low level. At the same time, the existing standard self-diagnosis system also does not give the opportunity to recognize the malfunctions of the electric gasoline pump. Theoretical analysis shows that the detection of uncertainty makes it possible to use test diagnostic regimes consisting in changing the parameters of electric power, as well as in the operating modes of the engine. The regularities of the change in the EGP pressure by current values and voltage, as well as their interrelations with the technical state of the elements, are established in the article, the modes for determining the technical state of the EGP are theoretically substantiated, the method and technology of the process of diagnosing electric fuel pumps in terms of current parameters of current strength and EGP voltage in testing modes is developed. It is recommended for motor vehicles and auto-repair enterprises to use these methods to reliably determine the technical condition of an electric gasoline pump and other elements of the fuel supply system.
