东风在6BT机国产化过程中立足于采用目前国内生产质量稳定、生产工艺成熟的直列柱塞式A型喷油泵（简称A型泵）。东风的决策得到美国公司、德国波许（Bosch）公司的认可和支持。型泵。共有6个分泵，分泵组成，泵体有铝合金铸成，主要包括泵油机构（柱塞偶件、柱塞弹簧、出油阀偶件和出油阀弹簧）、传动机构（凸轮轴和滚动挺柱）、油量调节机构（调节齿杆、调节齿圈和油量控制套筒）等部分。泵体上部设有纵向的低压油道与各柱塞套筒的进油孔相通。油道的一端有进油管接头，另一端有回油孔接头，多余的燃油通过溢流阀流回低压油路或燃油箱。柱塞套通和出油阀偶件从甭提上部装入，并由出油阀紧座压紧。为防止柱塞套筒转动，每个柱塞套筒都开有定位槽，装配时应使该槽对准每一个对应的定位销。柱塞泵油时应高压燃油冲击易引起金属穴蚀，挡油螺钉可减轻或消除该危害。柱塞、柱塞弹簧及滚轮挺柱等零件都是从泵体下部装入的，泵体底部设有拆装用的工艺孔。各孔用油底塞堵住。泵体侧面设有调整检视窗口，以便检查和调整供油量和供油提前角。调节齿杆装在泵体上部的纵向导孔内，在泵体背面中部有一个定位螺钉拧入齿杆的长形导向槽内，防止齿杆转动。凸轮轴装在泵体下腔内，用2个圆锥滚子轴承支撑。其结构上的主要特点为：①A型喷油泵采用整体式泵体，其刚性较好；②柱塞上部开有调节供油量的螺旋形斜槽和轴向直槽，可减少供油量随柱塞转动的化率，但也增加了柱塞偶件的侧向磨损；③油量调节机构未齿条式结构，该机构是柱塞式燃油泵最典型的的传统机构。传统的油量调节机构一般有拨叉式和齿条式两种。拨叉式机构在柱塞下端装有调节臂，壁的球头插在调节叉的槽里，调节叉用螺钉固定在油门调节杆上。推动气门调节杆，通过调节叉和调节臂，就可使柱塞转动。我国Ⅰ、Ⅱ、Ⅲ号喷油泵系列采用了这种形式的调节机构。齿条式机构的柱塞式5下部带有凸块，它嵌入油量控制套筒6转动，套筒6又通过下凹槽带动柱塞5相对于不动的柱塞套2转动，从而改变柱塞的有效行程，达到调节循环供油量的目的。各缸供油均匀性的调整，可以通过改变齿圈3和控制套筒6的相对位置来实现，即松开齿圈，按调整的需要使套筒6与柱塞5同时相对于可调节齿圈转过一定角度，再将可调节齿圈锁紧在套筒6上。④传动机构由凸轮轴、滚轮挺柱和柱塞弹簧等组成。传动机构中滚轮体部件的高度h用调整螺钉调节，从而改变相应分泵的供油提前角。这种结构因调整螺钉头部硬度的提高受到工艺上的限制，使用中容易磨损。
