【摘要】 利用遥感测量技术测量了Nissan货车在实际行驶工况下污染物的排放。根据测量结果,利用回归分析的方法对CO、HC和NOx等污染物的排放因子进行了估算,考虑了的瞬态车速和加/减速度的影响。测量结果表明,车辆的行驶工况对污染物的排放浓度及排放因子有明显影响。更多还原

【Abstract】 A Nissan van was used to determine the onroad motor vehicle emissions for the real urban driving cycles by using remote sensing measurement technique. A regression analysis approach based on the measured emission data sets was used to estimate the onroad emission factors of carbon monoxide (CO), hydrocarbon (HC) and nitrogen oxides (NOx) with respect to the effects of instantaneous vehicle speed and acceleration/deceleration for urban driving patterns. The measured emission data and estimated emission factors show that driving cycles have significant influence on the instantaneous gaseous emission characteristics and emission factor patterns. 更多还原
