In-line Injection Pump (classic)


 

   





The classical in-line injection pump had no electric connections at all. On the bottom on the right it is driven by a Diesel engine through a cam chain or spur wheels. In the center at the bottom a small part of the injection pump cam-shaft can be seen. Here the transport pump is flange mounted. The cam-shaft ends in the comparatively enormous centrifugal governor (on the left).
In the center, the springs of the individual pump elements can easily be seen. These end above in the connections for the injection lines to the individual cylinders. Above on the right the connection for the fuel pipe can be seen. It comes over by way of the main filter of the (not shown) transport pump. Above and on the right is the flow-back to the tank.
The high pressure is generated by the stroke of the individual pistons. These are driven through roller-tappets by the cam-shaft below. As can be seen by the spring compression, these are all in different positions. The injection pump shows the injection order of the six-cylinder diesel engine.
Directly above the springs, small, adjustable threaded clamping brackets can also be seen. These are evenly rotated by the control rod at the back of the pump. This mechanism adjusts the injection amount while the engine is running. In neutral and at max. RPMs, the centrifugal governer (left) intervenes in the adustment mechanism. The possible max. RPMs can be changed by means of the covers on the governer-casing. This can be done either to increase the performance (poor emmision values and illegal), or to lower the values of old, decrepid diesel engines.
