GLOW PLUG, NEW GLOW PLUG DETERMINATION METHOD, AND GLOW PLUG DRIVING CONTROL DEVICE |
摘要 |
There is provided a new glow plug that can be easily determined as to whether or not it is a new article. An additional circuit 12 formed by connecting a diode 13, a fuse 14, and an adjusting resistor 15 in series in this order is connected in parallel to a heating element 11 of a glow plug 1. The diode 13 is provided so as to have an anode located on the positive electrode side of the heating element 11 and a cathode located on the fuse 14 side. In the case of a unit inspection, by applying a positive voltage for test to a heating element negative electrode connecting portion 3a, it is possible to determine whether or not the glow plug 1 is normal without blowing the fuse 14 before the glow plug 1 is used in a vehicle. |
