采用WSL尾气比例采样器，对20辆经过厂家技术指标调整的在役汽油车的一氧化碳、总烃和氮氧化物的排放进行了道路测定。燃料消耗由碳平衡决定。一氧化碳和总碳氢化合物排放量最高的是在城市驾驶期间，平均时速约为17至22公里。随着平均速度的提高，这些排放量迅速减少，但在大约每小时80公里以上，一氧化碳排放量又开始上升。在总碳氢化合物的情况下，排放在每小时80公里以上的速度上升的趋势要明显得多。氮氧化物排放量与平均车速的变化并不一致，然而，时速113公里的排放量可能与城市价值相当，甚至高达2.4倍。本调查中确定的道路排放系数已被用来提供按车辆活动分列的车辆排放估计值的实例。(版权(C)官方版权，1983年12月。)
The emissions of carbon monoxide, total hydrocarbons and nitrogen oxides from a sample of twenty in-service gasoline engined cars which had been tuned to the manufacturers' specifications have been determined on the road using the WSL exhaust gas proportional sampler. Fuel consumptions were determined by carbon balance. The highest carbon monoxide and total hydrocarbon emissions occurred during urban drives in the average speed range about 17 to about 22 kph. As the average speed increased these emissions reduced rapidly, but above approximately 80 kph the carbon monoxide emissions started to rise again. The tendency for emissions to rise at speeds above 80 kph was much less marked in the case of total hydrocarbons. The variation of nitrogen oxides emissions with average speed was not consistent, however, emissions at 113 kph could be similar to or up to 2.4 times the urban value. The on-the-road emission factors determined in this survey have been used to provide an example of estimations of vehicle emissions on a vehicle activity disaggregated basis.
