国产摩托车欧Ⅲ排放解决方案及催化净化技术的应用

Solutions of Meeting EURO Ⅲ for Domestic-made Motorcycles and the Application of Catalytic Control Techniques

控制摩托车排气污染是一项系统工程,必须遵循先机内、后机外,内外协调的方针。无论是采用化油器还是电喷发动机,要满足欧Ⅲ排放标准,催化净化是最有效的技术手段。在对化油器优化的同时进行二次补气和催化转化是一种成本低、见效快的达标方案,而电控燃油喷射与三元催化净化则是满足欧Ⅲ及未来更严格排放标准的必然方向。

It is a systematic engineering for motorcycles to control emissions, which should abide by the principle of ＂inside the engine first＂, ＂outside the engine second＂ and the combination of the ＂two＂. No matter what engine is adopted, a carbureted engine or an EFI engine, for meeting EURO Ⅲ, the catalytic control is the best effective technically. Realizing the secondary gulping and catalytic conversion while optimizing the carburetor is of low cost and effective, and the principle of electronic-controlled carburetor and the three-way catalytic control is the inevitable direction of meeting EUROⅢ in the future.
