Development of oil filter elements diagnosis method for combustion engines
The paper presents a new method and means of diagnosing oil full-flow filter elements of combustion engine, theoretical and experimental studies are described. The experiments established the most sensitive diagnostic parameter in determining the technical condition of oil filter. The proposed method makes it possible to diagnose the degree of contamination and to determine technical condition of filter elements based on the differential pressure occurring at hydraulic impact at the time of instantaneous cut-off of the oil line discharge pipe after the filter. In addition, the time required for diagnosis as well as to evaluate technical condition of the motor is significantly reduced by eliminating the phase of disassembly of its components - the control is performed on-line (during operating cycle) of vehicles.
