Definitions
- Connection bolt which is electrically connected to a ceramic glow plug via a contact element, a further contact element connects the glow plug to the housing.
- One or both contact elements are used as a pressure sensor.
- glow plugs are generally proposed for car engines. These consist of a plug housing and a plug housing which projects out of the heating pin, which projects into its mounted state in the combustion chamber ⁇ a fuel combustion engine. As a rule, the glow plugs of the glow plugs protrude 4 mm into the combustion chamber of the fuel engine and heat the diesel-air mixture. The reached glow temperature and afterglow time of the glow plug have a significant influence on the exhaust gas behavior and the fuel consumption of the fuel engine.
- Sensor-integrative concepts in which a pressure sensor is arranged on or in the glow plug have the advantage that no additional borehole has to be provided in the fuel engine. This advantage increases all the more, since the space for attaching additional sensors is very limited in modern fuel engines.
- the object of the invention is to further develop a glow plug so that a pressure measurement in the combustion chamber of a fuel engine is possible in a simple manner.
- one or both contact elements of a ceramic glow plug are selected from a material that has physical properties that change reversibly and measurably under pressure flow (e.g. piezoelectricity, elasticity, or the like).
- One of the essential advantages of the invention is that the properties of the components previously arranged in a ceramic glow plug are used. This can save additional components.
- the geometry of the previous glow plugs is maintained, which means that no new modifications to the fuel engines are necessary and that the previous glow plugs can be replaced in a very simple manner by the glow plugs according to the invention with a pressure measuring device.
- FIG. 1 is a schematic representation of the glow plug according to the invention, partly in section;
- the contact elements 7a, 7b preferably have an elastic-plastic deformation behavior.
- at least one channel 8 is provided on the side of the glow plug 1 pointing towards the combustion chamber, which is connected to the area 9 in which the contact elements 7a , 7b are arranged, is in fluid communication.
- the pressure existing in the combustion chamber can also reach the area 9 of the contact elements 7a, 7b.
- the contact elements 7a, 7b deform and the change in resistance can be detected, for example, with the measuring device 11 shown in FIG. 2, the resistance 13 of the contact element 7a, 7b also being measured here in series with the resistance 12 of the glow plug 3 by the To be able to determine the change in current more precisely via the device 14.
