高效率的废气后处理系统

利勃海尔通过系统专业知识满足日益严格的排放标准。我们开发了自己的废气后处理系统,与我们的柴油发动机进行了最佳匹配。这些系统能够减少废气和有害颗粒的排放。

纵向整合一直欧式利勃海尔的悠久传统。我们自己制造关键零部件和系统。考虑到更严格的排放标准,我们决定采用自己的喷射系统,包括发动机控制系统。利勃海尔提供了一个标准的基础发动机。这种发动机可以根据模块化原理进行灵活调整,只需稍作修改,也可以根据废气后处理系统进行调整。这样,一个型号的发动机我们就可以满足不同国家和地区的不同排放法规。

对于废气后处理,利勃海尔在第四阶段和tier 4最终阶段均采用了SCRonly技术。经过优化的系统使我们能够在不需要柴油氧化催化剂(DOC)、颗粒过滤器(DPF)和废气再循环(EGR)的情况下满足排放极限值。通过及带的诊断系统对排放进行连续和精确的控制有助于提高效率。同时,提高了SCR催化转化器的效率。为了改进和更精确的计量,利勃海尔现在用注射器注入AdBlue尿素溶液,这允许更好的雾化,从而更有效地减少氮氧化物。

优势概述

利勃海尔(Liebherr)的SCRonly技术不含氧化催化剂和颗粒过滤器,在业内独树一帜。创新的系统具有许多优点:

  • 安装时节省空间
  • 重量更小
  • 无需定期清洁微粒过滤器
  • 更长的换油周期
  • 降低采购和维护成本
  • 由于没有废气再循环,冷却要求较低

利勃海尔已经在为2019年欧洲排放限值的第五阶段做准备,并开发了创新的SCRFilter系统。该系统已用于隧道掘进机,并通过了第四阶段以及瑞士市场的认证。利勃海尔解决方案包括DOC催化转化器、SCR催化转化器和SCR涂层颗粒过滤器。维护友好的技术允许很容易进入新的SCR过滤器。过滤器最早需要在4500个工作小时后清洗,这可以在利勃海尔自己的Reman中心完成。
