Injection Pump Applications Consideration 820502

The initial design of the Model DB2 fuel injection pump has served as a basis for continued development. The modifications required by three new engines (small industrial, passenger car and truck – 4, 6 and 8 cylinders respectively) introduced in 1981 provide a good example of this.
The major changes involved the pump mounting areas, the throttle designs, and fuel controls. Also, more stringent durability requirements had to be met in respect to higher temperatures and duty cycles.
As a result, the DB2 now offers greater capability towards future applications.
