PREHEATER
The preheater is a device for preheating the cooling
fluid before starting when operating at low
temperatures. The engine will start more easy.
Additionally the preheater will lengthen the life span
of the engine as there are no cold starts (see also
section Preheater (option)).
COLD WEATHER PACKAGE
The cold start option consists of larger batteries
and a blow off valve to be able to start the engine
at temperatures between -10°C (14°F) and -25°C
(-13°F). It also includes a preheater.
INLET SHUTDOWN VALVE
The inlet shut down valve is a safety device
preventing the engine from over speeding when
sucking in combustible fumes. When the engine max.
RPM is exceeded a pneumatically controlled solenoid
valve closes off the air inlet and the fuel supply to the
engine is cut.
