摘要： To simplify manufacture and provide a polarographic sensor of high response speed, operating according to the current limiting principle, an oxygen molecule migration barrier is provided leading to the cathode by separating the cathode from the space where the gas to be tested exists by a wall through which a hole is provided which extends therethrough to a small space immediately above the cathode defined by support elements placed immediately on the cathode. The hole, or a plurality of holes, is so dimensioned that the diameter thereof, with respect to its length, is small, with diameters of between 0.01 to 0.06 mm and a length of at least about 1 mm being suitable.

摘要： To measure partial oxygen pressure in gases, particularly exhaust gases of automotive-type combustion engines, a solid electrolyte plate of elongated rectangular configuration has at least one electrode pair applied to a single surface thereof, which is exposed to the measuring gas. Preferably, the gap between electrodes is elongated, by forming the electrodes in comb-interdigited form. A thermocouple - temperature sensor can be applied between connecting tracks for the electrodes which extend longitudinally of the electrolyte plate towards the other end thereof, through a sealing mass holding the plate within a housing, the other end forming, simultaneously, a connection terminal for connection to an electric connector or plug. A heating element can be placed on the obverse side of the plate, preferably in the position in the gap between the electrodes. More than one such sensor element may be secured in the same housing, and, for example, two such plates, back to back, with the heating element therebetween, spaced from each other, or as a common block. The sensor may be used for potentiometric and/or polarographic measurement, depending upon cover coatings on the electrodes which control exposure thereof to the gases, catalytic or non-catalytic action of the electrodes (for example being of platinum or gold, respectively) and whether a voltage is applied across the electrode terminals, or the sensor is to operate as an electrochemical cell. Such sensor can be inexpensively made, are suitable for mass production, and flexible with respect to their mode of operation.

摘要： To apply a measured quantity of air to the electrodes applied to a plate-like solid electrolyte body, which may be a chip on a carrier or may, itself, form the carrier, grooves, flutes, ducts, or depressions are formed in the carrier and/or a cover plate, the grooves terminating at an edge portion with access to the gas to be supplied, and having a size such that their clear height is preferably in the lower micron region, and a width, preferably under 1 mm, and particularly between 0.2 and 0.4 mm. The higher limits are applicable to apply, for example, air to a reference electrode, to apply ambient oxygen thereto; the lower limits are appropriate when operating the sensor as a polarographic sensor, in which the diffusion limited current, upon application of a bias voltage, is an analog measure of the oxygen concentration in the gas, and the gas supply to the electrode must be suitably controlled to prevent saturation conditions. The grooves may be formed, for example, by sandblasting or by applying insulating material in the form of posts, ridges, and the like, on the respective element, filling the space therebetween with a filler substance which, upon subsequent sintering, escapes, thus leaving the voids forming the grooves, depressions, and the like.

摘要： A method and apparatus is proposed for obtaining a control variable for the closed-loop control of the fuel-air ratio of the operating mixture of internal combustion engines, in which a threshold-current sensor of known structure is used. By means of varying the measurement voltage present at the threshold-current sensor by voltage amounts which correspond to a change in oxygen concentration to be expected in association with a change in operational state, the time behavior of the threshold-current sensor, which is essentially sluggish, is compensated for and it becomes possible to use it for rapidly-functioning closed-loop control systems in internal combustion engines.

摘要： An elongated plate element, for example of aluminum oxide, or a metal plate which is coated with an insulator such as aluminum oxide, is retained within a hollow spark plug insulator (15) by a sealing mass (38), for example a sinter compound, sintering together the plate element (37) and the insulator body (35). The plate element carries a strip or conductive track layer electrode (25) thereon, located, for example, on one major surface of the plate; at the ignition end, the plate may have a through-hole (52), plated through, so that the ignition electrode will have conductive portions at both sides of the plate, faced by ground electrode portions which likewise can be retained on plate-like carrier elements, and connected to the metal housing (11) of the spark plug via conductive tracks (60, 61) and a conductive sealing ring (17"). The plates can carry heaters (32) and operation sensors, such as gas composition sensor, temperature sensor, pressure sensor or the like, which may, for example, have one electrode connected to ground or chassis, and hence to the metal housing, and the other electrode carried along in strip form to the connecting end portion of the spark plug. The plate and layer-like construction of the insulating elements permits modular combination of required components having the desired operating and/or sensing characteristics, and are suitable for mass production assembly.

摘要： An ignition chamber device is described which has an elongated, rotationally symmetrical form. The wall of the ignition chamber which protrudes into the main combustion chamber of the internal combustion engine has a coaxial overflow conduit embodied by a nozzle and radially extending discharge conduits which extend into the annular chamber which surrounds the nozzle. The ignition chamber is provided with an ignition device which has a central electrode that leads from the outside into the interior and by means of this central electrode the ignition voltage is carried via a conductor path, disposed in the wall, to a wall location opposite the nozzle, from where the ignition spark can leap the gap. A heat pipe is disposed in the nozzle and includes a portion arranged in close proximity to the cylinder wall, which prevents the ignition chamber from becoming overheated and on the other hand also enables the inflowing mixture to be heated up in optimal fashion on the way to the ignition location.

摘要： To render output of a polarographic sensor essentially independent of aging of electrodes and temperature effects of the solid electrolyte body, within the operating ranges of the sensor to measure the oxygen composition of exhaust gases, the solid electrolyte plate of, for example, 50 mm length, 8 mm width and 1 mm thickness has a sensing electrode system including a cathode (2), and an anode (3) applied thereto, connected to a voltage source (7) of controllable output voltage. An oxygen molecule diffusion barrier (6) is applied to the cathode electrode. Additionally, a further electrode pair (5,4) is applied to the solid electrolyte body (1), serially connected in the current limiting circuit including the control voltage source. The voltage across one (2,3) of the electrode pairs is measured and compared with the voltage across the other electrode pair (4,5) voltage source, since the resistance of the zirconium solid electrolyte body drops with increasing temperature at roughly the same rate as the increase in limit current flow with increasing temperature. Both electrode pairs (2,3; 4,5) on the solid electrolyte body (1) are exposed to the gases, the oxygen content of which is to be analyzed.

摘要： A sensor (10) optically coupled to the combustion chamber (10') of an internal combustion (IC) engine is kept free from contaminating or dirt deposits, or the like, by subjecting the sensor to mechanical shocks or vibration. The mechanical shocks or vibration are obtained by the engine itself by controlling the engine to operate for a predetermined time period as set by a monostable flip-flop (FF) (18) under controlled knocking conditions, the shock waves within the combustion chamber causing flaking off or dropping off of contaminating deposits. Controlled knocking can be obtained by advancing ignition timing by additional control of an ignition system (19) in a direction of excessive spark advance, or overriding a knocking inhibiting system already present on the engine. The degree of contamination of the sensor can be determined, for example, by integrating the light received over a predetermined angle of rotation of the engine crankshaft and comparing this rotation with the amount of fuel supplied to the engine for combustion, for example by comparison with timing of a fuel injection pulse, or the like.
