As NOx and particulate emissions are very low at low engine load, any “conformity” test must be performed with the engine under high load. This requires either因为在发动机低负荷时NOx和颗粒排放非常低,任何符合性测试必须在发动机高负荷时进行. Emission measurements on vehicle in operation on road 车辆排放在道路上运转 Use of a roller test bed (for a truck, a very heavy / expensive device)使用转鼓试验台(对于卡车,非常重/装置昂贵) Dismounting the engine (and the after treatment system) from the vehicle and installation on an engine test bed从车辆上拆下发动机(和后处理系统)并安装到发动机排放试验台上. In-use compliance – 2 在用车符合性-2 European
