GENERAL
INFORMATION (GLOW SYSTEM)
SELF-REGULATING GLOW SYSTEM
The self-regulating
glow system enables the vehicle to start ideally at low temperature
by preheating the glow plug at super speed. When the ignition switch is
turned to the ON position,
the engine-ECU supplies electric currents and controls the glow lamp
illumination in accordance
with the engine coolant temperature. The control resistance wire built
in the glow plug has
a higher resistance as the glow plug temperature becomes higher. Because
of this, the currents
in the heater wire gradually decrease. The glow plug is stabilized at
the specified temperature. After
the engine start at low temperature, the current going to the glow plug
is controlled to perform
the stable combustion.
