Abstract: Compensation techniques for high temperature fiber-optic pressure sensors are aimed at correcting for the sensor sensitivity and offset dependence on temperature. By using materials of different thermal expansion coefficients for the sensor diaphragm (18, 28), housing (22), ferrule (10, 20) and fiber-bonding compound, and by optimizing the length of such parts, measurement efficiencies may be possible.

Abstract: Compensation techniques for high temperature fiber-optic pressure sensors are aimed at correcting for the sensor sensitivity and offset dependence on temperature. By using materials of different thermal expansion coefficients for the sensor diaphragm, housing, ferrule and fiber-bonding compound and by optimizing the length of such parts, the relative distance of the fiber tip with respect to the sensing diaphragm changes in a manner that reduces sensor sensitivity and/or offset dependence on temperature. In the first embodiment, the distance change results from controlled fiber movement within the ferrule and is used to reduce the temperature sensitivity of dynamic sensors. In the second embodiment, an optimum selection of the diaphragm, housing, ferrule and bonding compound materials yields a stable fiber position within the ferrule but, instead, a well defined ferrule movement with respect to the diaphragm in response to temperature changes. The latter technique is used to reduce the offset error of static sensors or the sensitivity error of dynamic sensors.

Abstract: Spark plug (20) integrated fiber optic combustion pressure sensors (30, 36) are configured to decrease heat and fatigue damage to the critical diaphragm (40) and fiber tip (37). A cup-shaped diaphragm (40) having non-uniform thickness reduces stress on the diaphragm and increases the reliability of the sensor. The effects of overpressure on the sensor are reduced by providing an angled portion (42) on the ferrule.

The sealing portion has a plurality of through openings configured to register with separate cylinder bore in the engine block wherein the sealing portion establishes a gas-tight seal about the through passages. A plurality of pressure sensor assemblies are attached in sealed engagement with the gasket body with at least one of the pressure sensor assemblies being configured to sense pressure within a separate one of the through openings. An electrical connector is supported on the gasket body radially outwardly from the sealing portion. The electrical connector is configured in electrical communication with each of the pressure sensor assemblies. Accordingly, the electrical connector is accessible without having to disassemble the gasket body from being clamped between the cylinder head and the engine block.

Abstract: A pressure-sensing element for an internal combustion engine is located in the sleeve of a ceramic glow plug heater having axial and radial pressure channels connecting the sensor diaphragm to the combustion chamber. The sensor signal conditioner is encapsulated in an automotive-type connector either directly attached to the glow plug body or located at the end of a cable pigtail containing the sensor fibers and the heater positive potential wire. A high temperature rated fiber optic pressure sensor capable of measuring either dynamic or absolute pressure is used. The absolute pressure sensor relies on three optical fibers combined in a common ferrule in the sensor head area and connected to one light source (LED) and two detectors (photodiodes) in the signal conditioner area. The fibers can either be identical by being spaced unequally in the ferrule or can have different diameters, numerical aperatures, or both, and be spaced equally or unequally. The fiber parameters or their spacing are selected to maximize the difference in the response of the "measurement" and "reference" detectors to changing pressure. In the integrated glow plug and pressure sensor above having a passage leading to the pressure sensor, a porous filter is inserted in the passage. The porous filter provides a four-fold improvement in pressure measurement by (1) acting as a trap for combustion deposits, (2) burning combustion deposits when the glow plug heater is on, (3) acting as a heat shield for reducing thermal shock error of the pressure sensor, and (4) damping acoustic high frequency ringing associated with the pressure passage.

The pressure sensor comprises an optical fiber (34) with a pressure diaphragm (36) at the tip to sense pressure and pressure changes within the combustion chamber (32) of a spark ignition engine. A channel (30) is provided in the spark plug to hold the sensor. The diaphragm (36) of the sensor is located closer to the spark electrode than to the electric conductor which is encased by the boot (12). The optical fiber (34) is contained within a shaft that is routed through the boot (12) and into the channel (30). The optical fiber (34) is operatively and electrically connected to the vehicle's engine controller. The opto-electric connection to the vehicle's engine controller is made adjacent a coil (72) in the boot (12) or removed from the coil (72). The fiber (34) is surrounded by a non-metallic shaft (22) outside the engine. Inside the spark plug (16), the shaft is metallic.
