摘要： Sensor apparatus for a multiple layer steel (MLS) cylinder head gasket measures combustion pressures for detecting engine conditions. A membrane is positioned at one end of an elongated metal tube, and the membrane end of the tube engages a cylinder bore boundary. A fiber optical sensor apparatus is fixed within the tube, and communicates with cyclic combustion events via the membrane. In one disclosed embodiment, optical wires from sensor apparatus situated at each engine bore are bundled into a common groove machined into an extended spacer layer radially outwardly of the conventional boundary of the gasket. The tube protects the sensor apparatus from damage of sealing stress on the gasket, and particularly at the bore perimeter. Each tube lies in a separate groove in the spacer layer that terminates at the bore boundary. A converter changes optical signals received from the apparatus into electrical signals for transmittal to a controller.

摘要： A multi-layer steel (MLS) cylinder head gasket containing fully integrated pressure sensors includes first and second metal layers with inner facing surfaces, and a spacer layer interposed between the facing surfaces. Outer (non-facing) surfaces of the first and second metal layers each include an elastomeric seal coating; the inner surfaces of the layers each include a friction reducing coating. Combustion apertures extend fully between the outer surfaces of the gasket, and are adapted to circumscribe cylinder bores of an engine. The spacer layer includes protective slots positioned adjacent each of the combustion apertures. Each slot wall contains a pressure sensor in form of a strain gauge to measure deflection of the wall resulting from pressure changes within engine combustion chambers. The measured deflections are correlated to actual pressures within the chambers. In the protective slots, the strain gauges are not exposed to combustion gases that could otherwise foul the sensors.

摘要： An improved fluid flow sensor for measuring changes in temperatures of fluids flowing through apertures of a multiple-layered gasket is embedded between layers of the gasket. A thermal resistor type of sensor based upon hotwire anemometer technology in a preferred embodiment is responsive to changes in fluid temperature and flow velocity. A primary resistance with external current leads and separate auxiliary leads for voltage sensing are employed, wherein changes in resistance are virtually linearly proportional to changes in temperature. A four-point probe measurement method provides a most accurate reading of the temperature data to the extent that resistance associated with lead and contact resistances are minimized. The thermal resistor sensor is constructed of relatively thin layers of dielectric and electrically conducting materials having a low thermal mass, wherein the dielectric layers serve as support and electrical insulation to protect the sensor from environmental deterioration.

摘要： Methods and materials for sealing and insulating a fuel cell plate are disclosed. The disclosed process includes applying a coating precursor on at least one surface of the fuel cell plate, and curing the coating precursor by exposure to radiation. Disclosed coating precursors include those containing an acrylated oligomer and a photoinitiator, which can polymerize in response to ultraviolet or electron beam radiation. Other disclosed coating precursors are those that can polymerize in response to exposure to infrared radiation or heating, and include epoxy nitrile resins and organopolysiloxane resins. The disclosed processes and coating precursors provide certain advantages over conventional methods and designs for insulating and sealing fuel cell plates since the disclosed coating precursors can be quickly and precisely applied to fuel cell plates by, for example, screening printing.

摘要： A cylinder head gasket seals combustion chamber openings with two exterior active sealing layers and a central spacer layer. In web areas between adjacent combustion openings, each opening beginning of the active layers has a land, where a circumferential main stopper is formed with the central spacer layer between the lands. Each active layer further has longitudinal waves formed with the active layer which, when compressed, form a longitudinal support wave stopper(s) in the web areas. Each web area active layer further has a full bead(s) in contact with the central spacer layer. For each exterior layer, in one case, two beads come together to form a single central web area bead that separates two wave stoppers. In another case, the two outer bead portions come together upon entering the central web area while a single wave stopper is formed between the two inner bead portions.

摘要： An improved heat shield provides for reduced noise transmission of vehicular engine components is disclosed. The heat shield has three layers; a first sheet layer, a center insulation layer, and a second sheet layer. The insulation layer is positioned between the first and second sheet layers. The first sheet layer is defined by a variable shaped periphery that is folded over the periphery of the second sheet layer to form a hem having a variable length around the heat shield. The variable length serves to reduce uneven strain in the hem area experienced during crush forming the heat shield into the final shape. Further, the variable length of the hem also serves to alter the resonate frequency of the heat shield in specific areas to reduce vibration and improve acoustical properties.
