The Characteristics of Spray and Exhaust Emissions Environmental Assessment of Adulteration and Convention Diesel

Adulterations fuel have been using in the vehicle in these days. Because gasoline, diesel prices are rising every day. sopeople find more cheap price fuel. Adulterations fuel caused a serious air pollution problems. Adulteration fuel were madefrom waste engine oil, waste paint. According to Government regulations permit to be used recycle fuel(adulteration fuel)only in industrial boiler. Unburned fuel pollutants are effected to human health. In this paper, the hazardous air pollutantscharacteristics in the diesel vehicles according to adulterations of vehicle fuels were carried out in the NEDC test mode inchassis dynamometer. It is revealed that the all of the regulation pollutants (THC, NOx, CO and PM) emission in the adul-terations of vehicle fuels was increased also the green house gas, CO 2 was increased. In the hazardous air pollutants char-acteristics, the VOCs(Volitile Organic Compounds) BTEX(Benzene, Toluene, Ethylbenzene, Xylene) emissions in the adulterationsof vehicle fuels showed higher level than these in the diesel fuels.
