实用新型内容
本实用新型的目的在于改进现有技术中的不足， 提供一种能够节油的 内燃机喉油管装置， 既节约能源， 又减少环境污染。
本实用新型的目的是这样实现的：
本实用新型提供一种内燃机喉油管装置， 包括喉油管， 其特征在于： 喉 油管内部固定至少一个雾化促进器。
一种优选方案， 其特征在于： 所述的喉油管下部出口处固定有一个雾化 促进器。
一种优选方案， 其特征在于： 所述的雾化促进器由至少含有两个叶片的 可转叶轮及与之轴接的固定支架组成。
一种优选方案， 其特征在于 .· 所述喉油管的雾化促进器的上部设有一个 以上的支管， 支管外接压差式阀门。
一种优选方案， 其特征在于： 所述喉油管的雾化促进器的上部设有两个 支管， 分别接有一个压差式阀门。
附图说明
下面结合附图对本实用新型作进一步说明。
图 1为现有内燃机喉油管装置结构示意图。
