Initial Results from the Auto/Oil Air Quality Improvement Research Program


The Auto/Oil Air Quality Improvement Research Program (AQIRP), a cooperative effort by the three major U.S. auto companies and fourteen oil companies, is the most comprehensive research effort ever undertaken to develop data on the air quality effects of the use of various motor fuels in various automotive systems and the relative cost-effectiveness of various fuel/vehicle combinations. Phase I of the Program, at a cost of about $15 million, is examining emissions and air quality impacts from current and older vehicles using reformulated gasolines with widely different values of aromatics content, olefin content, oxygenate content and type, sulfur content, vapor pressure (RVP) and 90% distillation temperature (T90). Emissions from Flexible and Variable Fuel vehicles using methanol/gasoline mixtures are also being examined. A second phase with a $25 million budget over three years has also been approved. Initial findings from the Phase I study and Phase II plans will be presented.
