Automotive suppliers, Federal-Mogul and Siemens VDO, have announced that they will jointly develop a combustion sensor that is integrated into the glow plug in diesel engine applications. This innovative sensor will, for the first time,enable the combustion to be monitored directly in the cylinder. Volume production is scheduled to start in 2006. This agreement covers both manufacturing and marketing of the new technology.
The injection system and the engine management play a vital role in reducing vibrations, noise, emission of pollutants and fuel consumption in modern diesel engines. Piezo common rail injection, brought on the market for the first time by Siemens VDO, support these targets by providing the option of multiple injection. In order to precisely control the combustion process in diesel engines, with multiple injections, Federal-Mogul and Siemens VDO will use a sensor that monitors the pressure curve directly in the cylinder through a sensor located in the glow plug, which facilitates the cold start of diesel engines.
