该发电机的排放解决方案由用于化学当量发动机的三元催化器组成。 三元催化器减少了自然进气发动机排气中的氮氧化物（NOX）、一氧化碳（CO）和碳氢化合物（HC）的排放。 三元催化器由含有铂金和其它铂族金属（PGM）的载体组成。
未处理的废气进入内圈组件（进口） (1) 。 在燃气通过催化基体 (4) 时处理废气。 经处理的废气通过内圈组件（出口） (6) 排出催化转换器。 使用 V 形带箍 (2) 和密封件 (3) 组成无泄漏组件。 可使用附加催化元件替换套筒 (5) 来增强催化转换器的处理能力。
催化转化器的正确安装对确保排放处理系统的所需性能和寿命起着重要作用。 涡轮增压器出口和转化器之间的管长对于符合所需性能有着重要作用。 催化转化器必须与发动机排气弯管紧密耦合。 靠近发动机的安装可允许升高催化器进口处的排气温度。 更高的催化温度可产生更好的催化转化效率。 靠近发动机的安装也提供了装置催化性能检修的方便性。
对于装有垂直排气管的应用设备，必须对催化剂加以保护，使其远离进入排气管的外部水分。
