PRESSURE-MEASURING GLOW PLUG

摘要

A pressure-measuring glow plug is proposed having a housing, in which a glow plug (21) for igniting a combustion mixture of an internal combustion engine and a pressure sensor (30) for detecting a combustion-chamber pressure of the internal combustion engine are arranged. The pressure-measuring glow plug has a connecting unit (40) which comprises a support (41) for receiving a signal processing unit (60) and a plug connection (52) with connector contacts (54) in a plug housing (50). At least one glow-module housing (20) for receiving the glow plug (21) and the pressure sensor (30) and an electronic-module housing (80) for receiving the support (41) are provided. The electronic-module housing (80) is connected at a glow-module-side connecting point (85) to the glow-module housing (20) and at a plug-side connecting point (86) to the plug housing (50).
