Title:
COMBUSTION PRESSURE SENSOR AND ITS ASSEMBLY IN AN ENGINE COMPONENT OF AN INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2018/084711
Kind Code:
A3
Abstract:
A combustion pressure sensor comprises a sensor body (9), at least one first optical fibre (1, 2) inserted into the sensor body (9), and a resiliently deformable membrane (7; 13) attached to the sensor body (9). The at least one first optical fibre (1, 2) is arranged for allowing measuring of a pressure induced deflection of the resiliently deformable membrane (9). An end (25) of the at least one first optical fibre (1, 2) is connected to the sensor body (9) in a manner that withstands temperatures within a range of temperatures hot enough to regenerate soot depositions on the resiliently deformable membrane (7; 13), yet cool enough to prevent melting of the resiliently deformable membrane (7; 13). When included in an internal combustion engine, at least one such combustion pressure sensor is positioned with its resiliently deformable membrane (7; 13) in direct contact with a surrounding body (8) of an engine component for direct transfer of heat to the surrounding body (8).
