  • Pressure glow plug for a diesel engine
    Patent number: 7337657
    Abstract: A pressure glow plug for a diesel engine has a glow plug body 2 for being inserted into a cylinder of the diesel engine, a heating rod 1 that is arranged in the glow plug body 2 and a pressure sensor 9 that is arranged between the heating rod 1 and the glow plug body 2 in such a way that the pressure in the combustion chamber of the cylinder that is transmitted by the heating rod 1 influences the pressure sensor 9. The heating rod 1 is arranged in the glow plug body 2 such that it can be displaced in an axially sliding fashion, namely by a corresponding sliding element, for example, a membrane 7 or seals 3.

  • Spark plug for an internal combustion engine and process for its manufacture
    Patent number: 6064144
    Abstract: A spark plug, especially one for a gas-fueled internal combustion engine has an electrically conducting spark plug body (1), a central electrode (3) which is located in the spark plug body (1) and which is electrically insulated from and projects away from the spark plug body (1), and a ground electrode (4) which is electrically connected to the spark plug body (1) and is made in the form of an annular electrode. The annular electrode (4) surrounds the front part of central electrode (3) such that an annular ignition gap (ZS) is formed between them. Surfaces of the central electrode (3) and the annular electrode (4) bordering the ignition gap (ZS) are provided with precious metal armorings in the form of sleeves (5, 6,), especially of platinum or a platinum alloy. This yields a spark plug with an extremely long service life.
