摘要： A terminal member (120) for an electrolyte sensor (24) having a first diameter section (122) separated from a second diameter section (124) by a shoulder (126). A stepped axial bore (138) extends from a second end (134) forward a first end (132). First and second passages (128 and 130) extend from the first end (132) to the second end (134). An axial slot (136) extends through the second diameter (124) to the stepped axial bore (138). First and second grooves (156 and 158) located on the periphery of the first diameter (122) extend to a first radial slot (160). A second radial slot (162) is offset from the first radial slot (160). The first and second radial slots (160 and 162) position terminals (164 and 164') connected to a heater member (92) located in bore (138) while first and second contact rings (142 and 144) are located on shoulder (126) and (140) to provide isolation for electrical paths between an external surface (80) and internal surface (82) of an electrolyte sensor (24).

摘要： An integrated LCC-based strain gage sensor, in which at least two LCC traces or strands run across a microcavity within the cylinder head gasket. In one aspect of the present invention, a system is provided comprising a signal source and a microcavity through which an input signal from the signal source passes and which alters the input signal as a result of a response of the microcavity to a strain. An LCC connects the microcavity and the signal source and an input signal propagates through the LCC. The microcavity may comprise one or more reflective surfaces which alters the input signal as a result of a change in a dimension of the microcavity. In another aspect of the invention, the microcavity produces an output signal that has an intensity or frequency different from that of the input signal upon undergoing a deformation.

摘要： A method for improving the atomization quality from a fluid injector includes the steps of inducing a first vortex turbulence in the fluid flowing past a first protrusion in a supply orifice having a flow axis therein, guiding the fluid through a turbulence cavity and then out through a first metering orifice having another protrusion positioned downstream from the first protrusion by a distance y measured generally parallel to the flow axis and by a distance x measured generally perpendicular to the flow axis. The droplet size of the fluid exiting from the metering orifice is reduced by sizing the x and y dimensions to position the first vortex turbulence within the turbulence cavity operatively adjacent to and upstream from the first metering orifice. In a preferred embodiment, the ratio of x/y is greater than 0.5 and less than 5. A fuel injector nozzle practicing this process is also provided.

摘要： A fuel injector for improving the atomization quality of fuel flowing into an internal combustion engine, includes a body having first and second turbulence cavities defined therein. First and second supply orifices in the body are coupled into their corresponding turbulence cavities for guiding the flow of fuel thereinto. First and second metering orifices in the body are coupled from corresponding first and second turbulence cavities for exhausting the atomized fuel therefrom in first and second fuel flows. One rim of each supply orifice is paired with a second rim of an adjacent metering orifice in order to produce a turbulence within the turbulence cavity. The metering orifice rim is spaced downstream by a distance y and laterally offset by a distance x from the supply orifice rim such that x/y is greater than 0.1. The fuel flowing from the first and second metering orifices includes lateral momentum components that cooperate to control the resultant cone angle of the fuel flowing from the injector. A plurality of hillocks are located within the turbulence cavity to enhance atomization. A method of operation for the apparatus is also provided.

摘要： A sensor (24) having a metal shell (30) joined to a sleeve (96) to locate a heater (92) in a thimble of an electrolyte member (72). A sealed joint is produced between the sleeve (96) and metal shell (30) to define a sealed reference chamber (118). A porous filter (112) in the sleeve (96) prevents water in environmental air from entering the reference chamber (118). Leads (106') and 106") which pass through the porous filter (112) are connected to terminal (164 and 164'). Terminals (164 and 164') located in a terminal member (120) position a heater (92) within chamber (118) and the electrolyte member (72). Leads (106 and 106.sup.n) which pass through the porous filter are connected to contact rings (142 and 144). Contact rings (142 and 144) are connected to an external and internal coating (80 and 82) on the electrolyte member (72). In response to a signal from a controller (26) electrical current is supplied to the heater (92) to maintain the temperature in chamber (118) above present limits such that changes in the ion conduction through the electrolyte member (72) is accurately measured. The changes result from a difference in the oxygen content of air in the reference chamber (118) as compared with oxygen in an exhaust gas supplied to the external surface (80).
