Description

节能降污多缸排气管
本实用新型属于柴油机排气管,尤其是一种节能、降污多缸排气管。现有市售的柴油机都存在整机震动澡声大,缸盖串气、废气排放污染现象。
本实用新型的目的在于提供一种结构简单、性能稳定、减少整机震动澡声及排气污染的节能降污多缸排气管系。
本实用新型的技术解决方案是这样的,通过发明人的反复试验,在柴油机排气管的气体导流管出口部分改成喇叭形状的导流管,使燃烧不完全的油雾经再次升温后燃烧,防止废气回流。导流管内设有消声隔板减少排气气阻压力,加快排放速度,消除排放气流互冲,从而减少整机震动及消除排放时所产生的澡杂声,导流管与消声隔板铸造成一体。
本实用新型经装玉柴6105机型负载路试了2500公里,证明整机震动、澡声、油耗及废气排放污染等方面比原机明显进步。已达到了柴油机在两个油咀工况不良的状况下,怡速时尾气排放基本无油味,并杜绝了缸盖串气故障的产生,而加速性能明显提高,延长柴油机的使用寿命。
下面结合附图和实施例对本实用新型进一步的说明。
附图为本实用新型的结构剖视主视图。
附图中,导流管(1)、消声隔板(2)、缓冲区(3)、总管出口(4)。
本实用新型的最佳实施方案是这样的,参照附图所示,在柴油机缸盖排气口尺寸不变的情况下,主要把排气管的气体导流管出气口部分改成喇叭形状的导流管(1),导流管(1)内设有消声隔板(2),隔板(2)下部是缓冲区(3),总管出口(4)与原车消声器相接,导流管(1)与消声隔板(2)铸造成一体。
