Glow plug system
A glow plug system control is integrated in the
Volkswagen Marine engine control unit.
The glow plug control contains the following
functions:
• Preheating
• Post-heating
• Standby heating
Functional description
Preheating
In view of the outstanding starting characteristics
of the Volkswagen Marine direct injection boat
engines, preheating (glow plug) is only activated
at temperatures below +9 °C. The engine control
unit receives the signal for the engine
temperature from the coolant temperature
sender.
The preheating procedure is started
automatically. The preheating time depends on
the current engine temperature.
An indicator lamp in the panel informs the
skipper that preheating is active.
