Abstract:
A method for controlling power supply of a pre-heat plug in an internal combustion engine to reach an ignition temperature for restarting the engine after the engine has stopped. The temperature of the pre-heat plug is determined using a first mathematical model and according to an elapsed engine-stop time, and additional energy to be supplied to the pre-heat plug for reaching the ignition temperature is determined using a second mathematical model and according to the temperature of the pre-heat plug.
