Description

本实用新型涉及一种改进的汽油车强制怠速节油器,属于汽车节油领域。
目前,市场上出售的节油器品种多,其中有一种电子电路自动控制的节油器,它由电磁阀的开闭,改变怠速喷油孔处气体的压力使其停止喷油。这种间接切断怠速油路,停止在强制怠速工况下供油的节油器,体积大,线路复杂,成本高,同时,该节油器的零件和各种线路的接点多,故障发生率高,影响其稳定性和使用寿命。
本实用新型的目的在于克服现有技术不足而提供一种自动控制、体积小巧、结构简单、灵敏度高,成本低的汽油车强制怠速气动自控节油器。
本实用新型的目的是这样实现的:节油器由自控部分和气体常闭开关组成并连成一体。节油器安装在化油器节气门的下端,使节油器的负压腔与化油器节气门的下腔相通,节油器起作用时,通过压气常闭阀的压气,经管路与化油器的怠速空气量孔与过渡孔之间的怠速油道相通。当汽车引擎处于强制怠速工况时,化油器节气门下腔形成很高的负压。此值传递到节油器的负压腔内,当腔内外压差产生的推力能克服弹簧和薄膜的弹力时,薄膜连同推杆向后移动,从而使常闭阀打开,压气由此经管路进入怠速油道,取消负压对怠速量孔处燃油的吸力,从而停止向引擎供油,达到节油的目的。
由于采用上述方案,本实用新型具有性能优越,体积小巧,灵敏度高,成本低廉,调整方便等优点,试用表明:节油率随驾驶员丢油门的累计时间和汽车行驶的瞬时速度的增加而增加。安装在中型货车上,在丘陵山区地段行驶时节油率可达10%以上,在纯下山路上行驶时,节油率可达50%以上。
下面结合附图和实施例对本实用新型进一步说明。
附图是本实用新型的结构示意图。
汽车运转在正常怠速工况下节油器下腔的真空度较小,传递到节油器负压腔的真空度也小。弹簧(5)的弹力经带推杆的薄膜(3)压迫压气常闭阀(2)使其关闭。当汽车处于强制怠速工况时,节油器下腔的真空度加大,节油器负压腔内外的压差值也随同增加,当此值通过薄膜(3)能克服弹簧(5)的弹力时,薄膜(3)上的推杆部分与压气常闭阀(2)脱离,使其开启,压气经过压气常闭阀和气管进入化油器怠速空气量孔与过渡孔之间的怠速油道,消除该处对怠速油量孔内燃油的吸力,从而截断此油路达到节油的目的。弹簧(5)预紧力的大小可以通过弹簧调整块(6)进行调整,以适应不同车型的需要。
