EMISSIONS OF UNREGULATED COMPOUNDS FROM FIVE DIFFERENT GASOLINE QUALITIES

Five different gasoline qualities have been tested in a co-operative project between the Swedish Environmental Protection Agency (SwEPA), OK Petroleum AB and Aspen Petroleum AB, performed at Motortestcenter (MTC). The gasolines ranged from pure alkylate to a market quality gasoline typical of Sweden 1993-94. The gasolines were emission tested in a Volvo 850 GLT, with adaptive fuel metering system. The catalyst was removed to get sufficient quantities of unregulated pollutants and samples for bioassays. The OICA type C modified ECE test cycle was driven. Unregulated as well as regulated emissions were measured. The results from the tests show that there is a substantial prospect of reducing the health effects from particulates and semivolatiles in the emissions from gasoline fueled vehicles. Also, small changes as the formulation of environmental class 2 gasoline will result in less harmful emissions and the reformulated quality (fuel 1) will definitely give much better emissions. Low PAH (polycyclic aromatic hydrocarbons) concentration in the gasoline has, for this vehicle, been shown to be more important for low emissions of PAH than low aromatic content in the gasoline. However there is a potential for an even greater decrease in emissions when changing to fuels containing a greater proportion of isoparaffins or which are pure isoparaffins. (A)
