Real Driving Emissions of Two Older Ordinary Cars Operated on High-Concentration Blends of N-Butanol and ISO-Butanol with Gasoline

Popis výsledku v původním jazyce

A Škoda Felicia car with a throttle body injection and a Škoda Fabia car with a multi-point port injection have been run on gasoline and its mixtures with up to 85% volume of ethanol, of n-butanol, and of isobutanol (2-methyl-1-propanol). An auxiliary control unit has been used with higher alcohol content. On each fuel, each car was driven 5-6 times along a local test route. The emissions of gaseous pollutants and other parameters were measured by a portable on-board emissions monitoring system. The results suggest that the engine control units of both cars prolonged the fuel injection pulse width allowing the engines to operate on all tested mixtures. On the throttle body injected engine, oscillations of air to fuel ratio to both rich and lean mixturecompositions were observed for all alcohol containing mixtures, especially for mixtures with high butanol share. This resulted to significant increase of nitrogen oxides emissions with a lack of significant decrease of carbon monoxide. O
