摘要
对100辆点燃式发动机在用汽油车进行遥感法和稳态工况法尾气排放对比实验。结果表明,三次遥感超标车辆遥感平均值与该车稳态工况值有线性关系。通过对稳态工况值(y)对遥感三次超标平均值(x)进行拟合分析,得到CO的拟合方程为y=-2.376x+1.028,NO的拟合方程为y=0.203x+0.794。两种方法建立的统一关系,对机动车污染有效控制和管理提供理论依据和数据支持。
A comparison experiment of exhaust emission between remote sensing method and steady-state operating method was carried out on 100 gasoline engines in use. The results show that the remote sensing average value of the three remote sensing over-standard vehicles has a linear relationship with the vehicle’s steady-state operating value. By fitting the steady-state operating value(y) to the remote sensing average of three over-standards(x), the fitting equation of CO is y=-2.376x+1.028, and the fitting equation of NO is y=0.203x+ 0.794. The unified relationship established by the two methods provides theoretical basis and data support for the effective control and management of motor vehicle pollution.
