Excess fuel device
NOTE!
The excess fuel device (1) must be pulled out
for cold starting.
Fig. 34: Excess fuel device
All engines are equipped with an excess fuel device (1) to make
starting them easier.
A lever limits the injection pump control shaft's path. If the starting
excess button (1) is pulled out when starting the lever allows a
longer path for the control shaft.
As soon as the engine has reached the maximum speed permitted
by the governor the mechanical speed governor pushes the control
shaft to stop and the starting excess button returns to its starting
position.
Therefore it is important that the engine is started without load
and can reach its maximum speed. Otherwise the starting excess
button does not return to its starting position and the engine is
overloaded.
NOTE!
When starting the engine when warm (operating
temperature) do not pull out the excess fuel device.
