Title: Abnormality detection device for glow plug
Inventor: MORIKAWA ATSUSHI
IPC: F23Q7/00
Filed: 2000-10-12
Abstract: PROBLEM TO BE SOLVED: To provide a device for detecting abnormality of a glow plug such as cable breakage in a diesel engine without installing special circuit or element for detection. SOLUTION: When the glow plug is switched from a glow off to a glow on (S460), whether abnormality is present or not in the glow plug is determined (S510, S520) based on the difference between the operating conditions of the diesel engine before and after the switching (control duty DF and final basic injection amount instruction value QFINC in the controller of an alternator) (S490, S500). The abnormality of the glow plug appears in the operating conditions of the diesel engine as the power source of energy. Accordingly, based on the difference between the operating conditions of the diesel engine before and after the power supply to the glow plug, whether abnormality such as the cable breakage of the glow plug and abnormal power supply to a glow relay is present or not is determined.  Thus, an increase in production cost can be prevented, and the deterioration of reliability and mountability can be eliminated.
