在汽车/油空气质量改善研究计划中，对不同的燃料/车辆系统进行了一系列广泛的排放测试。这些排放测试已用于模拟1995年和2005/2010年洛杉矶、达拉斯-沃斯堡和纽约的燃料/车辆变化对臭氧形成的影响。据估计，轻型车辆在1980/1985年的臭氧峰值中占28 - 37%，1995年降至7 - 18%，2005/2010年进一步降至5 - 9%。汽油的变化，显示出减少轻型车辆对臭氧形成的贡献的希望是烯烃含量，90%的蒸馏温度，硫含量和蒸气压的降低。原型灵活/可变燃料车辆中使用的甲醇/汽油混合物（M85）的结果取决于用于预测未来M85排放的假设。一项研究测试汽油产生的臭氧比洛杉矶和纽约的M85案例少，而在达拉斯-沃斯堡的M85案例中产生的臭氧更多或更少，这取决于汽油的浓度。
An extensive set of emission tests has been conducted in the Auto/Oil Air Quality Improvement Research Program on different fuel/vehicle systems. These emission tests have been used to model the impact of fuel/vehicle changes on ozone formation in Los Angeles, Dallas−Fort Worth, and New York in 1995 and 2005/2010. Light-duty vehicles are estimated to contribute 28−37% of the peak ozone in 1980/1985, decreasing to 7−18% in 1995, and further decreasing to 5−9% in 2005/2010. Gasoline changes that show promise in reducing the contribution of light-duty vehicles to ozone formation are reductions in olefin content, 90% distillation temperature, sulfur content, and vapor pressure. Results for a methanol/gasoline blend (M85) used in prototype flexible/variable fuel vehicles depend on the assumptions used to project future M85 emissions. A research test gasoline produced less ozone than the M85 cases in Los Angeles and New York and either more or less ozone than M85 in Dallas−Fort Worth, depending on the assumptio...
