ENGINE CLEANLINESS IN E85 POWERED FLEX-FUEL VEHICLES

Sažetak
E85 is viewed as a potential alternative fuel to decrease fossil CO2 emissions and dependence on crude oil. As for their conventional counterparts, engines powering flex-fuel vehicles deliver optimal performance when the sensitive areas in the intake system are kept clean and free of deposits. Since no standard tests are available for evaluating the tendency of fuels to form intake valve deposits in FFV engines fuelled with E85, interested parties such as fuel marketers or additive suppliers have to run in-house tests. This work focuses on experiments performed in a bench engine and vehicles operated on the road. The results demonstrate that additives based on polyisobuteneamine or polyetheramine are suitable to control the formation of intake valve deposits in this kind of engines.
