瑞典政府正在考虑一系列改善空气质量的建议,包括禁止使用柴油机车在市面上行驶。据称,在5年内斯德哥尔摩街道将禁止柴油车通过。至于汽油发动机的车辆则将于10年至15年内禁止使用。另一方面,目前瑞典开始对带催化涂层的金属滤清器做野外现场试验,这种金属滤清器装在柴油发动机的排气管里面,预计在降低有害气体的排放方面比催化排气净化器更有效。 The Swedish government is considering a series of recommendations to improve air quality, including the ban on the use of diesel locomotives on the market. Allegedly, diesel vehicles will be banned in the streets of Stockholm within five years. The petrol engine vehicles will be banned for 10 to 15 years. On the other hand, field tests are currently underway in Sweden for catalytic coated metal filters installed in the exhaust pipe of a diesel engine, which are expected to reduce emissions of harmful gases than catalytic exhaust Purifier more effective.
