技术领域

背景技术
伴随着国家机动车国六排放法规的实施,意味着对发动机的排放标准提出了更高的要求。天然气发动机作为商用车市场上的先行者率先施行国六排放标准,在天然气发动机前期研发过程中多数的发动机生产厂家选择了EGR技术路线。EGR(英文名为:Exhaust Gas Re-circulation,中文名为:废气再循环)系统中的废气需要重新回到发动机缸内,废气需要与新鲜空气和天然气预先混合再进入气缸。
在寒冷的冬天,因为EGR系统中的废气中存在大量的水分遇到低温的空气和燃气便会凝结成低温水附着在混合器体,在长时间低温环境下混合器体的温度和外部环境温度差异较小,所以混合气体的温度相对较低从而使附着在上面的水凝结成冰。所以随着发动机运行时间增加结冰会越来越大最终将整个混合器堵塞,影响发动机正常运行。
