GLOW CONTROL

System Description

INFOID:0000000000897322

Glow control involves controlling the glow plugs and the glow plugs "on" indicator light on the instrument panel
(via the can communication). The glow plugs are activated by a relay box and the power is provided by the
battery.
After the ignition is switched on. Preheating is activated for a period of time. The indicator light comes on for
the activation period which is dependent on the battery voltage, barometric pressure and engine coolant tem-
perature. When the engine coolant temperature is below a certain threshold, a postheating function enables
combustion stability, and thereby engine operation, to be improved (reduction in unburnt fuel and pollutant
emissions).
