Impact of a 10% Ethanol Blended Fuel on the Exhaust Emissions for Tier 0 and Tier 1 Light Duty Gasoline Vehicles at 35 Degrees F.

摘要

A study to evaluate the effects of oxygenated fuels on motor vehicle emissions at low ambient temperature was conducted by the Colorado Department of Public Health and Environment, Mobile Sources Section from April 1998 through December 1998. The purpose of the oxygenated fuel evaluation was to examine the effectiveness of oxygenated fuel as a CO reduction strategy on a cross section of late model motor vehicles. Questions were raised concerning the emission reduction potential of oxygenated fuels as a means to reduce CO in a 1996 report by the National Research Council entitled Toxicological and Performance Aspects of Oxygenated Motor Fuels. The council pointed out that very little data had been collected on the impact of oxygenated fuel on motor vehicle generated CO at low temperatures.
