20100284437 | PLUG-IN SENSOR FOR MEASURING AT LEAST ONE PROPERTY OF A FLUID MEDIUM - A plug-in sensor for measuring at least one property of a fluid medium, in particular for use in the coolant circuit of an air conditioning system of a motor vehicle. The plug-in sensor has at least one sensor for detecting the at least one property. Furthermore, the plug-in sensor has at least one sensor body having an external thread for threading the plug-in sensor into a threaded bore hole of a housing. Furthermore, the plug-in sensor includes a sealing surface for sealing an inner space of the housing against an outer space. The external thread has at least two threaded sections: a first threaded section including at least one continuous thread, and a second threaded section including at least one interrupted thread, at least one interruption of the at least one interrupted thread forming at least one blow-out groove. | 11-11-2010 |
20120024250 | IGNITION LASER - An ignition laser, includes a laser-active solid-state body, a housing and a combustion chamber window, the housing having an inner sleeve and an outer sleeve. An insert is provided between the inner sleeve and the outer sleeve, the insert and the combustion chamber window being joined sealingly and integrally. | 02-02-2012 |
20120037108 | Laser Spark Plug - A laser spark plug, in particular for an internal combustion engine of a motor vehicle is described. A fixing arrangement is provided in an end region of the laser spark plug facing the combustion chamber. The fixing arrangement allows an optical component to be detachably fixed to the laser spark plug. | 02-16-2012 |
20120125130 | CONTACTING MODULE FOR SENSOR HAVING LIMITED INSTALLATION SPACE - A sensor which encompasses at least one sensing element for recording at least one measured quantity. The sensor also has one sensor body for holding the sensing element. The sensing element has at least one connecting lead. The sensor has a modular design and includes a contacting module, whose design is separate from that of the sensor body, for electrically contacting the sensing element. The contacting module has at least one connecting element and at least one connector contact pin, the connector contact pin being surrounded in at least one connection region by the connecting element. The connector contact pin is electrically connected to the connecting lead. | 05-24-2012 |

20130133602 | LASER-INDUCED SPARK IGNITION FOR AN INTERNAL COMBUSTION ENGINE - A laser spark plug for an internal combustion engine includes at least one element for guiding, shaping and/or generating laser radiation, a combustion chamber window and a housing. The housing has, on the opposite side of the combustion chamber window from the element, an aperture for the passage of the laser radiation guided, shaped and/or generated by the element into a prechamber disposed at the end of the housing on the combustion chamber side. At least one overflow channel is provided for a fluid connection between an internal space of the prechamber and a combustion chamber surrounding the prechamber. When a fluid flows into the internal space of the prechamber through the overflow channel, a fluid flow is obtained that enters the interior of the aperture at a minimum angle ε, in particular measured with respect to the longitudinal axis of the laser spark plug, of 45°. | 05-30-2013 |
20130139774 | LASER-INDUCED SPARK IGNITION FOR AN INTERNAL COMBUSTION ENGINE - A laser spark plug for an internal combustion engine has at least one laser unit for guiding, shaping, and/or for producing laser radiation, a combustion chamber window, and a housing which has, at the side of the combustion chamber window situated opposite the laser unit, a screen for the passage of the laser radiation guided, shaped, and/or produced by the laser unit into a combustion chamber, the screen having a first end facing the combustion chamber and a second end facing away from the combustion chamber, the inner contour of the screen having an extremal cross-section in a region that is situated at a distance both from the first and second ends. | 06-06-2013 |
20140165945 | LASER SPARK PLUG - A laser spark plug, e.g., for an engine, includes a prechamber that accommodates an ignitable medium, an arrangement for radiating laser radiation onto an ignition point in the prechamber, at least one crossflow channel that enables a fluid connection between an internal space of the prechamber and an external space, and a screen arranged between the radiating arrangement and the prechamber with an outlet opening for entry of the laser radiation into the prechamber. The at least one crossflow channel is arranged to provide a fluid flow therethrough and into the prechamber, such that the direction of flow forms an angle of a maximum of approximately 30° with a longitudinal axis of the prechamber, and the flow is directed into a spatial region of the prechamber that is situated essentially predominantly, preferably completely, outside a central region of the outlet opening of the screen. | 06-19-2014 |
20140216383 | LASER SPARK PLUG AND COOLER FOR A LASER SPARK PLUG - A laser spark plug configured to be installed into a plug shaft of an internal combustion engine, and to focus laser ignition energy into the combustion chamber via combustion chamber-side, and thus proximal end, of the laser spark plug has, at a distal end of the laser spark plug opposite to the proximal end, a connecting unit for detachable mechanical and thermal connection to a cooler, the connecting unit being designed to permit the connecting and the disconnecting of the cooler when the laser spark plug is installed in the plug shaft. | 08-07-2014 |
