摘　　要：遥感检测技术在汽油车排气污染物监测领域的应用相对成熟,但在柴油车气态排放物检测方面的应用还不成熟,测试结果存在较大偏差.文中建立了柴油车气态排放物遥感测试数据的反演计算方法,依据柴油车排气烟羽中气体排放物各组分的相对浓度比值和该测试工况的柴油机过量空气系数,得到了柴油车尾气排放中各种气体排放物浓度.试验测试结果与车载排放测试结果接近,验证了柴油车气态排放物遥感测试数据反演计算方法的正确性.Motor vehicle emission remote sensing technology has achieved good application results in the field of gasoline vehicle emissions monitoring,but it is still immature in testing gaseous emissions from diesel vehicles due to the large deviation of the test results.In this paper,an inversion calculation method for remote sensing test data of diesel vehicle emissions is established.Based on the relative concentration ratios of various gaseous components in the exhaust plume of diesel vehicle and the excessive air coefficient of diesel engine under the test condition,the concentrations of various gas components emitted form diesel vehicle exhaust pipe are obtained.The remote sensing tested results of gaseous emissions in the diesel vehicle exhaust are close to the test results using PEMS,which verified the correctness and feasibility of the inverse calculation method used in remote sensing of diesel vehicle gaseous emissions.
