法国有关研究人员宣称,通过数年研究取得成功的窄角(narrow-angle)直接喷射技术能有效降低柴油发动机氮氧化物和可吸入颗粒物的排放量,并能“轻松”满足欧Ⅴ标准。 窄角直喷技术可从根本上抑制污染的产生,防患于未然;而传统技术往往通过滤清装置吸收已生成的污染物来达到降低排放的目的,这使得滤清器必须定期清洗更换,不仅费时费力而且价格昂贵。 将于明年全面实施的欧Ⅳ标准规定,每公里氮
French researchers claim that narrow-angle direct injection, which has been successful over the years, can effectively reduce emissions of nitrogen oxides and respirable particulate matter from diesel engines and “easily” meet Euro V standards. Narrow-angle direct injection technology can fundamentally inhibit the generation of pollution, take preventive measures; while the traditional technology often through the filter device to absorb pollutants have been generated to achieve the purpose of reducing emissions, which makes the filter must be regularly cleaned replacement, Not only time-consuming and expensive. The Euro IV standard to be fully implemented next year will provide nitrogen per kilometer
