ABSTRACT
The basic criterion in using alternative fuels, specifically ethanol blends, consists in its pro-ecological properties. However, like in the case of conventional hydrocarbon fuels, the use of blended ethanol in combustion engines can result in formation of harmful engine deposits. The addition of DCA (Deposit Control Additive) type fuel improvers is the most effective approach to prevent harmful deposit formation. However, such additives, although widely used in engine petrol types, are usually not fully compatible and hence effective in the case of ethanol fuels. Because of this, an effective DCA was developed under the carried out project, dedicated to ethanol fuels. The project was aimed at carrying out a comparative assessment of the impact of the developed DCA additive to ethanol fuels on engine emission and fuel consumption. Using a chassis dynamometer test with exhaust gas analyzers and Fourier-transform infrared spectroscopy, regulated emissions of CO, NMHC, HC, THC, NOx and PM, PN were investigated, as well as CO2, and unregulated emissions of CH4, HCHO, MeCHO, NH3, ETOH. This allowed evaluating, whether the use in ethanol fuels of a new DCA, of effectiveness confirmed in tests, creates a threat in the field of increased emission of a combustion engine supplied with so improved fuel.
Key Words: Ethanol blends, Engine deposits, Deposit control additive, Regulated and unregulated emissions
