Abstract

该实用新型定名为“供油定时自动调节器”,应用 于单缸柴油机,可随柴油机转速的变化自动调节供油 时间,填补了国产单缸高压油泵没有设置供油定时调 节的空白,对提高柴油机的热效率,特别是减少主要 零件的磨损,具有显著的作用。

Description

本实用新型使用于单缸柴油机齿条式喷油泵。是向单缸柴油机提供一种随转速变化自动调节供油定时的供油定时自动调节器。供油定时自动调节器其原理是改变单缸喷油泵柱塞全行程中的空程,不改变柱塞的有效行程。属内燃机技术领域。
本实用新型的目的是为单缸柴油机提供一种供油定时自动调节器,能使单缸柴油机在各种转速下都是最佳供油提前角,提高热效率。能使单缸柴油机低转速运转平稳。消除低速敲缸现象,延长单缸柴油机主要零件(如活塞肖、连杆铜套、轴瓦)的使用寿命。
图1是本实用新型的剖面图。
下面结合图1说明依据本实用新型提出的具体工作情况。
该装置包括一个调节下座(1),与调节下座用左旋螺纹连接的调节上座(2),调节上座(2)上部制成凸耳(3)。右旋使调节上、下座距离伸长,左旋使调节上、下座距离缩短。该调节器装入齿条式喷油泵内。
本实用新型的目的是这样实现的:当喷油泵最大供油时,调节齿轮带动左旋螺纹的调节上座右旋一个角度,使调节上、下座距离由原来的0.5毫米(装配距离)升到0.9毫米,其高度恰好等于原喷油泵弹簧下座的高度,柴油机供油提前角为19°,保持了柴油机原标定转速的供油提前角。
当喷油泵减油时,调节齿轮带动调节上座向左方向转动一个角度,调节上座向下移动0.5毫米距离,柱塞跟之下降,延迟了遮闭柱塞套回油孔的时间,供油提前角与柴油机转速相适应。
