摘要： A multi-layer steel cylinder head gasket (10) includes a spacer layer (26) between two beaded mirror image outer layers (30, 32). A wire ring stopper (24) extends about the boundary of a combustion opening (16) in the stopper layer (20); the ring is radially spaced from the mirror image beaded outer layer extremities (46, 48). The ring is covered by a flange folded thereover; the flange extends radially outwardly to overlie the boundary edge of the stopper layer at the combustion opening (16). The stopper ring pre-stresses the gasket interface at the combustion opening upon securement of a cylinder head to an engine block. Because the stopper ring is spaced from the beaded outer layers, the stresses imposed on the wire ring are decoupled from the beaded outer layers, and lower incidences of bead cracking are realized. In addition, the wire ring diameter is greater than the thickness of the stopper layer, reducing unnecessary compression loads on the stopper layer.
摘要翻译：多层钢制气缸盖衬垫（10）包括在两个串联的镜像外层（30,32）之间的间隔层（26）。线环止动器（24）围绕止动层（20）中的燃烧口（16）的边界延伸; 环与镜像珠状外层末端（46,48）径向间隔开。环被折叠在其上的法兰覆盖; 凸缘沿径向向外延伸以覆盖在燃烧口（16）处的阻挡层的边界边缘。当气缸盖固定到发动机缸体上时，止动环在燃烧口处预先施加垫圈接口。由于止动环与珠状外层隔开，所以施加在线圈上的应力与珠状外层分离，实现了较小的胎圈裂纹发生率。此外，线环直径大于止动层的厚度，减少了止动层上的不必要的压缩载荷。

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.
摘要翻译：包含完全集成的压力传感器的多层钢（MLS）气缸盖垫片包括具有内表面的第一和第二金属层和插入在相对表面之间的间隔层。第一和第二金属层的外（非面向）表面各自包括弹性体密封涂层; 这些层的内表面各自包括减摩涂层。燃烧孔完全在垫圈的外表面之间延伸，并且适于围绕发动机的气缸孔。间隔层包括邻近每个燃烧孔定位的保护槽。每个槽壁包含压力传感器，其形式为应变仪，以测量由发动机燃烧室内的压力变化引起的壁的偏转。测量的偏差与室内的实际压力相关。在保护槽中，应变计不会暴露于否则会污染传感器的燃烧气体。

摘要： Sensor apparatus for a multiple layer steel (MLS) cylinder head gasket (10) measures combustion pressures for detecting engine conditions. A membrane (40) is positioned at one end of an elongated metal tube (22), and the membrane end of the tube engages a cylinder bore boundary (12). A fiber optical sensor apparatus (60) is fixed within the tube, and communicates with cyclic combustion events via the membrane. In one disclosed embodiment, optical wires (34) from sensor apparatus situated at each engine bore are bundled into a common groove (24) machined into an extended spacer layer (20) radially outwardly of the conventional boundary of the gasket. The tube (22) protects the sensor apparatus (60) from damage of sealing stress on the gasket (10), and particularly at the bore perimeter. Each tube (22) lies in a separate groove (24) in the spacer layer (20) that terminates at the bore boundary. A converter changes optical signals received from the apparatus into electrical signals for transmittal to a controller (62).
