This paper examines the effects of particulate contaminants, biofuel fraction and blended fuel temperature on the hydraulic parameters of filtration in a diesel engine fuel supply system. The aim is to substantiate a calculation approach for determining pressure drop and filter operating time to a specified limiting value, accounting for retained particle accumulation. The methodology combines a contaminant mass balance with a model of the resistances of the clean filter medium and the cake in series at a constant volumetric fuel flow rate. Analytical relationships are obtained for calculating pressure drop, limiting retained contaminant mass, time to the specified pressure drop and minimum effective filtration area. Calculations are performed for biofuel volume fractions of 0, 15 and 30%, temperatures of 20–40 °C and particulate contaminant concentrations of 5–20 mg/L. In the baseline calculation example, at a flow rate of 100 L/h and a filtration area of 0.050 m², increasing contaminant concentration from 5 to 20 mg/L reduces the time to a pressure drop of 30 kPa from 39.47 to 9.87 h. Under the assumed relationship between viscosity and fuel composition, increasing the biofuel fraction from 0 to 30% at 20 °C reduces this time by 31.8%. To provide a calculated filtration time of 20 h at a contaminant concentration of 10 mg/L, the required area is 0.0503 m² for B0 and 0.0595 m² for B30. A normalised additional resistance index is proposed, which, within the adopted model, makes it possible to separate the effect of contaminant accumulation from the direct effects of fuel viscosity and flow rate. Local sensitivity coefficients of the calculated time to the principal parameters are determined. For the baseline conditions, the sensitivity coefficients with respect to flow rate and filtration area are −2.20 and 2.20, respectively, confirming the need to account accurately for these quantities when assessing filter condition. The numerical results are obtained by analytical calculation using specified parameters; no experimental validation of a specific filter is performed within this study. The practical significance of the proposed relationships lies in their potential use for test planning, preliminary selection of filtration area and substantiation of parameters for a fuel filter condition monitoring system. Application of the model to a specific fuel supply system requires determination of its coefficients from measurements and validation of the predicted time to the limiting pressure drop.
