Description

一种满足国六排放的柴油机后处理电控智能管理***
技术领域
本发明涉及柴油机后处理电控技术领域，尤其涉及一种满足国六排放的柴油机后处理电控智能管理***。
背景技术
近年来，我国各大城市连续出现雾霾现象，严重危害人们健康，影响我国国际形象。控制柴油机尾气中的氮氧化物和颗粒物排放是治理城市空气污染的关键。柴油机是支撑我国国民经济发展的重要产品，每年柴油机保有量以18％的速度递增，环保压力巨大。另一方面，我国排放法规日益严格，NOx的排放限值从国四阶段的3.5g/kW.h降低到国六阶段的0.4g/kW.h，NOx的排放限值从国四阶段的0.02g/kW.h降低到国六阶段的0.01g/kW.h。原有的机内净化技术已无法满足新的排放要求，必须增加排放后处理***。在世界范围来看，以选择性催化还原技术和壁流式颗粒捕集器技术来降低柴油机氮氧化物和颗粒物排放已经成为共识。如何有效的控制柴油机主要排放物PM和NOx，国内主要采用颗粒捕捉器(DPF)实现PM的氧化处理，再在后级加上选择性还原***(SCR)完成NOx的还原处理。SCR通过向尾气中喷射尿素水溶液，经过“选择性催化还原”过程，将尾气中的氮氧化物转化为无害的氮气和水蒸气。DPF***和SCR***运行状态都随着发动机工况变化而不断变化，加装DPF后处于再生周期时，发动机排气温度会升高。而过高的DPF燃烧温度会大大降低SCR的使用寿命，甚至造成SCR***的永久性损坏。
