一、分配式喷油系的种类与特点分配式喷油泵（以下简称分配泵）是国外50年代后期才开始推广使用的新型喷油泵。其特征是用一组供油元件通过分配机构定时定量地将燃油分别供给各气缸。因此，分配泵的零件数目少，结构比较简单，体积小，重量轻，制造成本低和维修方便。另外它的
First, the type and characteristics of distributed fuel injection system Distributed fuel injection pump (hereinafter referred to as the distribution pump) is a new type of fuel injection pump started to promote the use of foreign 50’s late. The utility model is characterized in that a group of oil supply components are used to supply fuel to each cylinder regularly and quantitatively through a distribution mechanism. Therefore, the number of pump parts distribution less, the structure is relatively simple, small size, light weight, low manufacturing costs and easy maintenance. In addition it’s
