20090316328 | Method for Controlling a Glow Plug in a Diesel Engine - A method for controlling a glow plug in a diesel engine, in particular in the preheating phase, is described. According to the invention, it is provided that the time gradient of an electrical variable which varies according to the temperature of the glow plug is measured and compared with a threshold value, and when said time gradient exceeds or drops below the threshold value, the electric supply voltage of the glow plug is changed. | 12-24-2009 |
20090323250 | GLOW PLUG CONTROL DUAL MODE FAULT DIAGNOSTICS - A glow plug control system for a vehicle comprises a mode control module and a fault diagnostic module. The mode control module enables one of a first mode and a second mode of operation based on a period of time that a glow plug is ON during a drive cycle. The fault diagnostic module selectively diagnoses a fault based on a first message, a second message, and a third message when the first mode is enabled and selectively diagnoses the fault independent of the second and third messages when the second mode is enabled. | 12-31-2009 |
