Conversion Factors for Hydrocarbon Emission Components (EPA-420-R-05-015, May 2003)
ثبت نشده
چکیده
Purpose The purpose of this memorandum is to document the conversion factors for reporting hydrocarbon emissions in different forms. The general forms are total hydrocarbons (THC), total organic gas (TOG), nonmethane hydrocarbons (NMHC), nonmethane organic gas (NMOG), and volatile organic compounds (VOC), all defined in the introduction below. For reporting hydrocarbon emissions from nonroad equipment, it is helpful to provide an accepted means to estimate the hydrocarbons in the different forms. This is not a substitute for full speciation of hydrocarbons in the exhaust.

T amount of pollution that a vehicle emits is dependent on many factors. The U.S. Environmental Protection Agency (EPA) has developed a series of computer models that estimate the average emis sions for different types of highway vehicles. This fact sheet is one of a series on highway vehicle emission factors. It presents average emis sion rates for gasoline-fueled and diesel heavy-duty vehic...
