Fuel limiting device(g.208-209)
When starting up the engine the fuel limiting device has the aim
of preventing excessive smoke at the exhaust.
Use the delivery adjustment rod of the injection pumps 5 Fig.209
in a constant manner when ambient temperature is above 15°C.
As the temperature gradually falls, this device gradually lessens
its action to then exclude it at 0°C.
