柴油车排气后处理装置技术要求和试验方法 中国汽车技术研究中心 胡 毅 2005年12月15日 纲要Presentation Outline 一、背景 Background 二、柴油车排气后处理系统介绍 Diesel Aftertreatment System Introduction 三、法规要求 Regulation Requirements 四、技术方法 Technical Approach 五、总结 Summary 背景Background 1. 中国将于2007年1月1日执行满足欧III排放的重型柴油机标准，2010年1月1日将执行满足欧IV排放的重型柴油机标准（GB 17691-2005)。 China will require HD to meet Euro III emissions standards in 1/1/2007. Euro IV is planed for 1/1/2010 (GB 17691-2005) 2. 基于现在的柴油机和柴油车技术，为满足欧III和更严格的排放法规，加装后处理系统是必需的。 Based on the current diesel engine and vehicle technologies, aftertreatment systems may be required in order to meet Euro III and above regulation requirements. 3. 所有的后处理系统在装车前，将进行测试和认证。 All aftertreatment systems will need to be tested and validated before they are equipped to the vehicles. General test procedures will be required to test the candidate aftertreatment systems in order to meet the needs from all the engine and vehicle manufacturers. Diesel aftertreatment technologies and evaluation procedures exist in the leading markets in the US, Europe and Japan. The draft procedures are being developed based on the existing procedures. 背景Background 4. 必须制定切实可行的测试规程，来满足所有发动机和车辆制造商的要求。 General test procedures will be required to test the candidate aftertreatment systems in order to meet the needs from all the engine and vehicle manufacturers. 5. 在美国、欧洲和日本主要市场都有柴油车后处理技术和评价方法。 Diesel aftertreatment technologies and evaluation procedures exist in the leading markets in the US, Europe and Japan. 6. 草案方法是在国际现有的测试规程上建立起来的。 The draft procedures are being developed based on the existing procedures. 柴油车排气后处理系统介绍Diesel Aftertreatment System Introduction 柴油车排气后处理系统介绍Diesel Aftertreatment System Introduction 法规要求Regulation Requirements 1. 柴油车后处理系统的性能是在发动机台架上完成的。后处理系统包括DOC、DPF、SCR和LNT。 Performance of the diesel aftertreatment systems will be tested on engine dynomometer benches.
