由于柴油机的尾气排放对大气的污染较为严重,尤其是“冒黑烟”是一种极为直观的污染,致使柴油车受到相当程度的偏见和歧视。近年来在我国一些大中城市屡遭“封杀”,使不少地区的柴油车市场急剧萎缩。 对柴油车排放的控制究竟应采取什么样的措施?是“堵”还是“疏”?我们认为应该用科学的态度去分析,对柴油机尾气污染应采用科学技术手段来进行治理和改善,而不应一味采取“堵”或“封杀”的行政手段去限制。 实际上,柴油机是热效率最高的内燃机。与汽油机相比,柴油机有其优越的动力性能和燃油经济性,对于车辆
As the emission of diesel engines is more polluting to the atmosphere, “black smoke” in particular is an extremely intuitive pollution that causes a considerable degree of prejudice and discrimination on diesel vehicles. In recent years, some large and medium-sized cities in our country have repeatedly been “banned”, so that the diesel vehicle market in many areas has been rapidly shrinking. What kind of measures should be taken to control the emission of diesel vehicles? Is it “blocking” or “sparse?” We think we should use a scientific attitude to analyze the exhaust gas pollution of diesel engines should adopt scientific and technological means to carry out governance and improvement, and not Should blindly adopt “blocking” or “blocking” administrative means to limit. In fact, diesel engines are the most thermally efficient internal combustion engines. Compared with the gasoline engine, diesel engine has its superior dynamic performance and fuel economy, for vehicles
