“…Lambda (λ) is more important than fuel composition for CO emissions. This finding is in agreement with those of previous studies (Goodfellow et al, 1996;Zervas et al, 2003).…”

“…The λ appeared to be more important than fuel composition in the case of CO emissions for the test motorcycle. These findings agree with those of previous studies conducted on cars (Goodfellow et al, 1996;MacKinven and Hublin, 1996;Zervas et al, 2003).…”

“…Two large-scale studies, the Air Quality Improvement Research Program (AQIRP) by automobile and oil companies in the United States in 1989, and the European Programme on Emission, Fuels, and Engine Technologies (EPEFE) by the European Commission in1992, were conducted to evaluate the impacts of gasoline composition on exhaust emissions and air quality. The experimental design and results of AQIRP and EPEFE have been reported in previous articles (Pahl and McNally, 1990;Koehl et al, 1991;Gorse et al, 1992;Rutherford et al, 1995;Goodfellow et al, 1996;McArragher et al, 1999). Furthermore, in order to understand the effects of lead-free gasoline and reformulated gasoline on vehicle exhaust emissions, several studied have been conducted using various vehicle modes (different model year, new and in-use, or passenger cars and light-duty trucks) to quantify their effects (Perry and Gee, 1995;Zervas et al, 2003;Schifter et al, 2004;Yucesu et al, 2006;Chen et al, 2011).…”

“…It has been evidently that aromatic content of gasoline may affect on benzene emissions from vehicle (McArragher et al, 1996;Zervas et al, 1999;Prati et al, 2000). These emission factors from various test fuels (i.e., A15, A25, and A50) were applied to evaluate the effects of fuel aromatic content on benzene emissions.…”

“…The result is power generation procedures that are not as complete as those in automobiles, and that may contribute to poor engine combustion efficiency. Furthermore, because motorcycles are smaller and lighter than cars, and are used primarily to travel short distances at lower speeds, there are significant differences in both fuel consumption and pollutant emissions (Didyk and Moyano, 2001;Tsai et al, 2003).…”

A new four-stroke carburetor motorcycle engine without any engine adjustments was used to study the impact of fuel aromatic content on exhaust emissions of criteria air pollutants (CO, THC, and NO x ). Three aromatic fuels were tested, containing 15, 25, and 50% (vol) aromatics mixed with gasoline. A commercial unleaded gasoline was also tested as a reference case (RF). The experimental data indicated that a lower aromatic content (25 and 15 vol%) in gasoline reduced the amounts of THC and NO x by more than 10% compared to the reference fuel (aromatic content 30 vol%). CO emissions, on the other hand, did not appear to be related to the aromatic content of gasoline. The excess air ratio (λ) values for the aromatic test fuels were lower than 1.0, i.e., under fuel-rich conditions, and CO emissions increased due to lack of oxygen. In contrast, high NO x emissions appeared in a near stoichiometric air-fuel ratio, and decreased as the fuel mixture approached lean or rich conditions. The results also showed that decreasing the aromatic content from 50 to 25 and 15 vol% in gasoline may result in a reduction of benzene emissions from the motorcycles without a catalyst converter. This study shows that decreasing the aromatic content in gasoline may reduce the emissions of THC, NO x , and benzene, but not CO, from four-stroke carburetor motorcycles.
