导读：国四农机排放的技术路线有哪几种形式？其技术成熟吗？
【农机网 热点关注】为积极回应社会和广大用户的关切，更好地推进农机国四排放法规的实施，中国农机企业家峰会组织编写了《国四排放农机产品100问》手册，意在普及国四排放农机产品的法规和知识，对排放升级中大家关心的问题答疑解惑，便于农机生产企业、农机经销商、农机使用者以及基层农机管理人员进一步了解和认识国四农机产品，更好地开展相关工作。
五、后处理系统篇
46、国四农机排放的技术路线有哪几种形式？其技术成熟吗？
答：本次非道路国四排放标准，排放限值等同于欧ⅢB，但又增加了PN限制等内容，可谓是独具特色的排放标准，将欧盟欧ⅢB、欧Ⅳ、欧Ⅴ融合了进来，还增加了道路国六的内容，技术难度大。
总体而言，国四标准产品，采用选择性催化还原置(SCR)和颗粒物捕集器(DPF)是主流技术路线，大部分企业还会采用柴油氧化催化器(DOC)和废气再循环(EGR)等辅助技术：低功率区间，大部分企业采取高压共轨+EGR+DOC+DPF路线；高功率区间，采用高压共轨+DOC+DPF+SCR路线；也有部分企业在居中部分低功率区间采用高压共轨+EGR+DOC+DPF路线。
对于
柴油机生产企业而言，这些技术在国五、国六道路用柴油车上已实现成熟应用，欧美非道路相应产品已在十多年前供应市场，技术升级和产品验证、实验基本都已经完成，但国三升级到国四不仅仅更换
发动机即可，更换一个满足非道路国四排放的发动机，工作量仅完成了30%，后续70%的工作都要在整机上进行，各种匹配、优化，以及整机PEMS测试等。
关于DPF的有关知识、使用和注意事项，请见附录一、DPF
关于SCR的有关知识、使用和注意事项，请见附录二、SCR
关于PEMS的有关知识、使用和注意事项，请见附录四、PEMS
47、国四产品带有DPF，在田间作业特别是收获机作业时容易引发火情吗？预防着火的办法有哪一些？ 答：国四产品和之前的产品的最大区别在于增加了一套后处理系统，后处理系统排气部件与之前产品的排气管及消声器一样，运行温度很高，为此在产品结构上，增加了后处理隔热、防护装置；日常使用中需要保证后处理系统排气部件周围的清洁，避免杂物堆积引发火灾。
另外，如果在尿素箱中误加柴油也会引发火灾，在使用中需要注意避免油液添加错误。车辆操作手册和相关部件周围都进行了相关的说明并做了相关的注意事项以及安全警告标贴，请在操作机器前熟读产品操作手册。用户在日常使用和保养中注意相关安全警告标贴的内容，以做到安全使用设备。
目前非道路国四采用的技术手段在道路车辆以及欧美已经非常成熟，根据国外同类产品多年的使用经验来看，并未发现由于排放升级加装后处理系统而引起火灾发生率升高的情况。
48、DPF再生的方式有哪些？
答：DPF的再生方式分为有ECU干预的主动再生(一般技术上指碳和氧气的高温反应>550℃)和没有ECU干预的被动再生(一般技术上指碳和NO2的低温反应<450℃)。主动再生又称强制再生，分为行车再生(机器正常工作)和驻车再生两种方式；被动再生不需要人工干预。
服务站再生是指去服务站做DPF再生，当服务再生DPF指示灯发出指示，发动机出现限扭，就代表需要进行服务再生。
行车再生和驻车再生特点：驻车再生较为安全。行车再生效率高，不耽误正常工作，但需注意行车再生的周围环境。
具体再生操作流程请参见生产厂家的使用说明书。
49、所有国四产品需要驻车再生吗？
答：市场上的部分国四农机产品不需要驻车再生，其再生是在作业过程中自动进行的，无需人工干预。只有在未及时添加尿素，使用了劣质的柴油、机油和尿素，以及后处理系统产生的相关报警没有及时处理的情况下，才需要进行驻车再生或者专业技术人员现场开展强制再生。
50、DPF被动再生时，发动机转速自动增加，是否正常？
答：正常，这是DPF被动再生时清除积聚污染物的正常操作，此时仪表会有相应的提示。
51、国四后处理对于农业机械是否有特殊的设计？
答：农机后处理均增加了后处理隔热防护装置(设置防火隔热棉，外加隔热板、防护罩等)，对后处理零件起到防护作用，并对农作物秸秆、碎屑进行防护阻挡，一般农机产品的后处理系统的主体部分在机械壳体内，且排气口方向朝上或斜上，通过这些措施有效防止火情。此外增加黄色防烫标识警示，用于提醒用户此零件为高温部件。
52、对于农业机械后处理装置的清理是否有特殊要求？
答：建议每次使用前检查后处理装置的情况，清理后处理周边的农作物秸秆、碎屑，以防止农作物碎屑堆积过多引发火情。
53、后处理系统常见典型故障有哪些？
答：尿素泄漏、喷嘴堵塞、电气传感器故障(排温、压差、尿素质量等)、DPF系统故障(堵塞、再生失败、移除等故障)、SCR系统故障(SCR效率低、结晶堵塞、载体脱落等故障)，这些故障会以故障代码的形式在产品的显示屏上显示 ，便于报修和维修。
