Abstract: The fuel quality is being regarded in this article as the crucial impact factor, which determines the following technical properties of the mobile agricultural vehicles as the reliability and the overall efficiency. Going on in their application alongside with the traditional fossil types of fuels, the bio-ones, being derived from the renewable sources, are being regarded as more and more popular. However, the biofuels are exhibiting the distinct chemical compositions, regarding the main properties and characteristics in the comparison to the petroleum-based ones, making it necessary to continue the further development of the modern storage, transportation and processing materials. The scientific article provides the solid proof basis for the application of the highly porous polymeric materials of the spherical forms for the process of the purification of various fuel types. These materials were synthesized via copolymerization of multiple monomers, including resorcinol, formaldehyde, styrene, divinylbenzene, and carbamide. The polymeric materials demonstrated remarkable inertness towards biofuel, with no discernible changes observed in either the filters or the fuel samples after prolonged contact. The tensile strength of PGS polymer samples ranged from 15.5 to 21 MPa, while their compressive strength ranged from 2.5 to 6 MPa. Fine fuel filtration achieved with these polymer materials had an absolute precision of 10 microns, with a purification efficiency ranging from 92% to 95%. The proposed model for the design of the self-cleaning filter, being produced from the PGS polymers allows in its` turn the simultaneous purification of fuel from any mechanical impurities and provides the step-by-step filter regeneration, so enabling the prolonged service life without the maintenance.
