Abstract
The paper presents results of a study of operational reliability of electronic control of an automotive engine fuel supply subsystem. Impacts on the structural elements of the subject subsystem stipulated by physical and chemical processes of heat transfer and dissipation, absorption of magnetic and electric fields, wear and tear, etc., leads to occurrence of various kinds of damage in them. Causes of the subsystem getting inoperable and the effect of failures of its elements on the engine operation are revealed. Considerable attention is paid in the paper to the diagnostics of the technical state of order of the sub-system which must be performed in scheduled car maintenance intervals in accordance with the developed method and algorithm. The deviation of the fuel pressure in the fuel rail from the setpoint in the electronic control unit was taken as the diagnostic parameter for the evaluation of the technical condition of the subsystem. Using Microsoft Excel, an analytical equation was selected that describes the dependency of the diagnostic parameter deviation versus the running time of the vehicle allowing for the substantiation of its rated values. The results of the performed studies were tested and introduced into the technological processes of maintenance and repair of Peugeot cars of “Auto Tract Peugeot” dealership, Vladimir City.
