IMPROVING OPERATIONAL PERFORMANCE OF AIR PURIFIERS FOR INTERNAL COMBUSTION ENGINES OF KAMAZ VEHICLES BY APPLYING INNOVATIVE SYNTHETIC MATERIALS

The article presents the assessment and analysis of the influence of air dustiness on the operation of the serial filter element of the air cleaner (CE) of the KAMAZ-740 engine with a serial paper filter element (PFE) 740-1109560-02 type DFV 5801 and made of bulk synthetic materials (BSM): po-rous plastic propylene and fluoroplastic-4. As a result of the experimental studies, it was found that the specific dust capacity of the CE with BSM type DFV 5801 is within 1.5 kg/m2, for BSM made of propylene on natural dust it was 1.7 kg/m2, made of fluoroplastic-4 in a dual version it reaches up to 2.6 kg/m2. Consequently, based on the analysis of the studies, it can be concluded that filter elements made of bulk synthetic materials are superior to paper ones in specific dust capacity. It is pos-sible to carry out maintenance more than once, with virtually no changes in performance indicators and use at high humidity and low temperatures.
