  • Passive, high-temperature-resistant resistor element for measuring temperature in passenger and commercial vehicles
    Patent number: 7061363
    Abstract: A passive, high-temperature-resistant resistor element for measuring temperature is provided, the resistor element having an essentially interior insulating layer and two exterior conducting layers of a ceramic composite structure; the conducting layers being connected to one another at the tip of the resistor element; and the ceramic composite structure including trisilicon tetranitride, a metal silicide, and yttrium oxide or trisilicon tetranitride, a metal silicide, and a matrix phase of SixOyCzNw, where x signifies 1–2, y signifies 0–2, and w signifies 0–2. A combination element of this resistor element and a sheathed type glow plug, for example, is also provided.

  • Device for monitoring the combustion process in internal combustion engines
    Patent number: 6668630
    Abstract: A device is proposed for monitoring the combustion process in internal combustion engines, a direct monitoring and a monitoring of individual combustion processes, in particular individual combustion chambers, being possible. This is achieved using a waveguide, which is integrated in a component, which protrudes into the combustion chamber.
