摘要： An oxygen sensor utilizes a chrome oxide compensating resistor (5) in series with a titania sensing resistor (3). The chrome oxide resistor (5) not only compensates for the effects of temperature on the titania sensing (3) resistor, but since it exhibits (p) type behavior while the titania exhibits (n) type behavior in the presence of gaseous oxygen, the sensitivity of the sensor is increased. The resistors (3, 5) can be applied as a film to a substrate (7) or they can be formed as discrete chips. Substantial quantities of alumina and glass can be added to the chrome oxide without affecting oxygen sensitivity although the electrical resistance rises substantially.

摘要： The invention is a method of making a pressure tight seal for a glow plug characterized by applying a high current to heat a groove (31) in the outer shell (3) of a glow plug while simultaneously pressing together the sealing elements adjacent the groove i.e. an insulator (2), a gasket (1), the flared end (42) of a protective tube (4) and a shoulder (32) within the shell (3). The grooves (31) concentrates the heat and allows the shell to be compressed around the elements of the seal.

摘要： A temperature compensated oxygen sensor has a generally cylindrical first insulator with an axial bore extending therethrough which is counterbored at one end. A second cylindrical insulator is retained in the bore in the first insulator either by a radial inwardly directed flange on the second end of the first insulator or by a radial outwardly directed flange on one end of the second insulator which seats in the counterbore of the first insulator. A titania resistor and a compensating resistor are mounted on the second end of the second insulator by leads extending through longitudinal bores in a second cylindrical insulator and into the counterbore in the first insulator. The leads are connected to terminals which are retained in the counterbore either by a chemical bonding agent or by a third cylindrical insulator through which the terminals extend. The third insulator can be secured either by mechanical means and/or by a chemical bonding agent including a glass preform.

摘要： A method and apparatus for measuring the O.sub.2 content in an exhaust gas of an internal combustion engine by exposing two resistors to the exhaust gas of an internal combustion engine. The resistance of both resistors varies as a function of the temperature of the exhaust gas to which it is exposed. However, the resistance of one of the resistors also varies as a function of the oxygen content of the exhaust gas. Therefore, an electrical signal can be obtained which is a function of the O.sub.2 content of the exhaust gas, with the temperature effect of the exhaust gas on the resistor being minimized or eliminated.

摘要： A zirconia type oxygen partial pressure sensor for use with an exhaust system wherein an electrical voltage signal is generated in response to an oxygen partial pressure differential across a solid electrolyte. A reference oxygen partial pressure is introduced into the interior of a solid electrolyte sensor through an aperture formed in a housing for the sensor, a protective clip, wire mesh or spring being provided to at least partially cover the aperture to preclude contaminants from being introduced to the interior of the sensor through the aperture. A ground terminal assembly is also provided to supply a ground for the device in addition to that provided by the threaded engagement between the shell of the O.sub.2 sensor and the exhaust system to which it is attached.

摘要： A method and apparatus for obtaining an electrical signal which is a function of the 0.sub.2 content of the exhaust gas of an internal combustion engine. Two resistors (1 and 3) are exposed to the exhaust gas of an internal combustion engine. Both resistors (1 and 3) have a resistance which varies as a function of the temperature of the exhaust gas to which it is exposed. However, the resistance of one of the resistors (1) also varies as a function of the oxygen content in the exhaust gas. Therefore, by applying a voltage to the resistors an electrical signal can be obtained which is a function of the O.sub.2 content of the exhaust gas, with the temperature effect of the exhaust gas on the network output being minimized or eliminated. The resistors (1 and 3) that form the sensing elements (10) are connected in series to other resistors to form a first and second resistor network which is connected together in parallel circuit relationship.

摘要： A wide range combustion mixture air/fuel ratio sensor in which an electrochemical cell supplies hydrogen gas to a palladium sensor element at a rate regulated by the output of a Wheatstone bridge circuit incorporating the sensor element. This generated hydrogen gas combines with any oxygen present in the exhaust gas through catalytic action and also maintains the level of absorbed hydrogen, and therefore the electrical resistance of the palladium sensor element, at a preselected value. The magnitude of the current applied to the electrochemical cell necessary to maintain this balance is a measure of the combustion mixture air/fuel ratio.
