When flammable gas is drawn into the engine, shutting off the fuel supply will not stop the engine
right away. In order to shut down the engine quickly and reliably in these events, the intake of the
combustion air must be interrupted.
If a certain engine speed is exceeded, the engine controller closes the engine air shut-off valve for
intake air. This brings the engine to an immediate stop.
4.6.4.2 Option la
Spark arrestor
Sparks in exhaust fumes represent a considerable risk in environments with flammable materials.
Flying sparks combined with flammable materials may cause fires and explosions.
A spark arrestor on the exhaust silencer is required when operating a diesel engine in a fire hazard
area and in forestry and agricultural applications. In such applications, a spark may ignite flamma‐
ble materials.
The spark arrestor prevents the exhaust silencer emitting any glowing fuel residue.
4.6.5 Option ga
Generator option
A generator is installed to provide a power supply to electrical consumers. The generator is driven
from the engine by a drive belt. A tensioning device automatically ensures optimum belt tension.
4.6.5.1 Operating modes
The compressor works with the normal air delivery regulation and generates electrical power at the
same time.
The generator can work in two modes. These are selected by the mode switch:
■ Automatic cut-in
■ Continuous load
Generator main switch
Mode selector switch
