Description

一种歧管式催化转化器
技术领域
本发明涉及汽车部件技术领域，尤其涉及一种歧管式催化转化器。
背景技术
随着现代化进程的加快以及汽车工业和交通运输业的发展，城市汽车的保有量正在快速增长，由此而引发的空气污染也越来越受到人们的重视，机动车捧放标准也越来越严格。我国已于2010年7月1日开始实施了GB18352.3-2005轻型车第Ⅳ阶段标准，新标准对汽车冷启动的排放进行了严格限制。为了满足新法规，歧管式催化转化器应运产生。它安装更接近缸体，利用通过催化器的高温尾气能够快速预催化剂使之达到起燃温度从而较大地提高转化效率，降低排放。
歧管式催化转化器安装在发动机排气系统中，其所处位置的特殊性要求其具有更高的机械强度和热强度。由于比传统催化转化器更靠近发动机，使得歧管式催化转化器受热负荷更加严重，特别是在发动机大负荷运行时，这种情况更为突出：此外，由于发动机在常温到高温、高温到常温的激热、激冷交变状态下长期使用，使得这种催化器长期受到具有一定角度剧烈的热冲击，这就要求在催化转化器设计时，不仅要考虑交变机械冲击的振动载荷，还要考虑高温和交变热载荷对歧管式催化转化器的影响。因此，解决歧管式催化转化器的热负荷和热强度问题是提高整个排气系统技术水平的关键。
发明内容
本发明的目的在于提出一种歧管式催化转化器，能够使得系统具有较高的热稳定性及可靠性。
为达此目的，本发明采用以下技术方案：
一种歧管式催化转化器，其包括衬垫、载体、催化剂、歧管、前后端盖、壳体、前后法兰和隔热罩，载体负载有催化剂，衬垫包裹所述载体并位于壳体内，歧管与壳体相连，其特征在于，所述催化剂为Pd/Ce-Zr/Al2O3，歧管和壳体采用Al-Si合金，所述Al-Si合金按重量百分比含有Si 12-14％，Cu 0.05-0.1％，Mg 0.3-1.2％，Ni 1.5-4％，Fe 0.4-1.4％，Cr0.5-1.5％，Al余量。
本发明采用特定配方的Al-Si合金，以及特定的耐高温催化剂，使得所述歧管式催化转化器在高温下结构稳定，同时，其催化转化效率高。
具体实施方式
下面通过具体实施方式来进一步说明本发明的技术方案。
