BACKGROUND Methanol has become an alternative fuel for gasoline, which is facing a rapidly rising world demand with a limited oil supply. Methanol-gasoline has been used in China, but phase stability and vapor lock still need to be resolved in methanol-gasoline applications. In this paper, a series of tartaric esters were synthesized and used as phase stabilizers and saturation vapor pressure d...

We model a municipal solid waste (MSW)-to-ethanol facility that employs dilute acid hydrolysis and gravity pressure vessel technology and estimate life cycle energy use and air emissions. We compare our results, assuming the ethanol is utilized as E85 (blended with 15% gasoline) in a light-duty vehicle, with extant life cycle assessments of gasoline, corn-ethanol, and energy crop-cellulosic-eth...

Methane in soil gas may have undesirable consequences. The soil gas may be able to form a flammable mixture with air and present an explosion hazard. Aerobic biodegradation of the methane in soil gas may consume oxygen that would otherwise be available for biodegradation of gasoline hydrocarbons. The consumption of oxygen by methane may increase the chance of completing a vapor intrusion pathwa...

The U.S. Environmental Protection Agency initiated a pilot program in 2002 with researchers at the University of Michigan Air Quality Laboratory to investigate motor vehicle mercury emissions. The program included exhaust emissions characterization of vapor and particulate phase mercury from three light-duty gasoline vehicles, one diesel vehicle and mercury analysis of fuel, lubricating oil, en...

Experimental research has been conducted on the effect of ignition timings characteristics and performance gasohol engines such as power, torque, specific fuel consumption, thermal efficiency. The used in this is pure gasoline a mixture 50% bioethanol (BE50). results show that timing gives maximum occurs at top bottom dead points 9 degrees for 12 BE50 fuel. Furthermore, power obtained 6,500 rpm...

Methanol, as a promising carbon-neutral fuel, has become research hotspot worldwide. In this study, pure gasoline and blended with five different volume ratios of methanol (10%, 20%, 30%, 50%, 75%) were selected test fuels, which referred to M0, M10, M20, M30, M50, M75. The experiments on carbon pollutant emissions performance carried out passenger vehicle direct injection (GDI) turbocharged en...

Gasoline engine exhaust has been considered as a major source of air pollution in China. Due to lower cyto- and geno-toxicity effects of methanol engine exhaust, methanol is regarded as a potential substitute for gasoline. We have previously compared cyto- and geno-toxicities of gasoline engine exhaust with that of methanol engine exhaust in A549 cells (Zhang et al., 2007).To characterize the i...

This paper examines the link between oil market and motor fuel in Sweden by developing a joint structural VAR model. We explore dynamic relationship (both gasoline diesel) focusing on effects of demand refinery shocks price consumption. The results reveal opposite responses diesel consumption to positive shocks. Moreover, response both is greater than that also assess immediate long-run contrib...

Di methyl carbonate (DMC) has a lot of good properties to be used as a blend with gasoline. In order to improve the efficiency, combustion stability and emission performance of a spark ignition engine, oxygenated fuel (DMC) is added to a gasoline. In this experimental work, the effect of using 100% gasoline and gasoline-DMC blends (D5, D10, D15 and D20) on four cylinder engine performance and e...
