(2) Pre-heating time control based on battery voltage

GCU monitors the battery voltage. If it is low, GCU extends the pre-heating time.

GCU monitors the energy to glow plugs (the amount of pre-heating energy is always same).

-

GCU monitors the battery voltage. If it is low, GCU extends the pre-heating time to get enough

energy.

-

GCU monitors the battery voltage. If it is low, GCU increases PWM duty..

(3) Power control

GCU PWM control

This describes the voltage supplying types to glow plugs.

-

GCU estimates the temperature of glow plug for pre-heating. To avoid the power loss and overheat,

GCU supplies the lowest power for getting target temperature when turning ON the ignition from

OFF.
