Abstract
Description
Die Erfindung betrifft eine Glühkerze für einen Brennraum eines Dieselmotors.The The invention relates to a glow plug for one Combustion chamber of a diesel engine.
Glühkerzen für Dieselmotoren bestehen wesentlichen aus einem Glühstift aus Metall oder Keramik, der in den Brennraum des Motors hineinragt und durch eine elektrische Heizwendel im Innern des Stiftes beim Starten des Motors zum Glühen gebracht wird. Der Glühstift ist axial mit einem Einschraubkörper verbunden. Die elektrischen Anschlüsse der Heizwendel erfolgen dabei über einen axialen Kontaktstift und über das metallische Gehäuse der Glühkerze.glow plugs for diesel engines consist essentially of a glow plug made of metal or ceramic, which projects into the combustion chamber of the engine and by an electric Heating coil inside the pin is made to glow when starting the engine. The glow plug is axial with a screw-in body connected. The electrical connections of the heating coil take place over it an axial contact pin and over the metallic housing the glow plug.
Die Anforderungen an die Reduzierung des Schadstoffausstoßes von Dieselmotoren werden immer höher und es werden Sensoren im Brennraum benötigt, um die Verbrennung gezielt beeinflussen zu können. Der Zugang mit Sensoren zum Brennraum eines Dieselmotors kann am leichtesten über die Glühkerze erfolgen.The Requirements for the reduction of pollutant emissions of Diesel engines are getting higher and sensors are needed in the combustion chamber to target the combustion to be able to influence. The access with sensors to the combustion chamber of a diesel engine can at lightest over the glow plug respectively.
