STUDY OF THE INFLUENCE OF BIODIESEL FUEL ON CONSTRUCTION MATERIALS OF TRANSPORT VEHICLES
Abstract
Biodiesel is considered as one of the most common biofuels used to replace conventional motor fuels. Some of the problematic issues related to the operation of vehichles using biodiesel fuels are disscussed, among which is quick deterioration of metal and polymer details of fuel system. The reasons for this problem that is connected to the structure and propeties of biodiesel fuel is analyzed. The influence of conventional diesel fuel, biodiesel fuel and its blends on metals (copper and steel) and rubber materials (polyvinylchloride) during long-term storage was studied. For the experiment the biodiesel fuel based on camelina oil ethyl esters was used. Highly aggressive impact of biodiesel on copped was found. Steel is considered to be resistant to corrosion in the medium of biodiesel.biodiesel similarly as conventional diesel fuel lead to degradation of rubber materials causinf its swelling. Basing on the achieved results the set of measures and reccomendations for providing reliability and durability of vehicles operation using biodiesel or its blends was developed and proposed.
