摘要： A method for determining the temperature of a sheathed-element glow plug during operation in an internal combustion engine is described, in which a temperature-resistance reference correlation is determined. In order to reduce the tolerance range of a sheathed-element glow plug, after the sheathed-element glow plug has been installed in the internal combustion engine, a calibration step is carried out in which, with the aid of the temperature-resistance reference correlation determined prior to the installation of the sheathed-element glow plug in the internal combustion engine, a temperature-resistance correlation specific to the sheathed-element glow plug is ascertained, from which the temperature of the sheathed-element glow plug during operation of the sheathed-element glow plug in the internal combustion engine is determined.

摘要： An autonomous glow driver system for radio controlled (RC) engines. Aspects of the system include a connector that securely attaches to the glow plug to maintain good electrical contact with the glow plug and reduce signal noise and using a current and differential amplifiers to determine the temperature of the glow element and the RPMs of the glow engine from a voltage signal (obtained via the connector) that varies with the temperature as induced changes in the resistance of the glow element occur. Using the data of temperature, non-running RPM, and running RPM to control operation of the glow driver leads to a very reliable approach to automatically activating the glow driver to maintain the combustion chamber temperature of the glow engine at a selected level because RPM is indicative of a rotating engine whereas temperature is not.

摘要： The presence or absence of degradation and abnormality is determined with high reliability by measuring a resistance value of a glow plug, which is in an operating state, as a latest resistance value. A method then determines whether or not the rate of the change of the latest resistance value with respect to an initial resistance value of the glow plug exceeds a first predetermined value. The method also determines whether or not the rate of the change of the latest resistance value with respect to a last resistance value that is a resistance value of the glow plug, which has been recently measured at the time of the acquisition of the latest resistance value, exceeds a second predetermined value when the rate of change of the latest resistance value with respect to the initial resistance value of the glow plug exceeds the first predetermined value. The method determines that the glow plug is in an abnormal degradation state when the rate of the change of the latest resistance value with respect to the last resistance value exceeds the second predetermined value.

摘要： The accuracy in controlling the heating temperature of a glow plug and the reliability of the control operation are improved.An electronic control unit 101 is configured such that a standard applied voltage for glow plugs 50-1 to 50-n is set according to the engine speed and the load conditions of the engine. In addition, a correction coefficient set in advance according to the temperature classification of the mounted glow plugs 50-1 to 50-n is readably stored in the electronic control unit 101 as a correction coefficient map. By multiplying the standard applied voltage by a correction coefficient K read from the correction coefficient map and applying a voltage of the multiplication result to the glow plugs 50-1 to 50-n as a driving voltage through the power circuit 102 to perform driving control, stable and reliable heating temperature control can be realized regardless of variations in the heating temperature characteristics.
