摘要： A portion of the exhaust gas of an internal combustion engine is returned to the induction manifold through an exhaust gas recycling line. This recycle line contains one or more orifice plates to create a measurable pressure drop when gas is flowing. The gas flow through the recycle line may be interrupted in controlled manner by a valve, particularly a magnetically actuated valve. The pressure drop across the orifice plate or plates is sensed by pressure-responsive electrical switches which provide input signals for a logical circuit that energizes a signaling device to warn the operator of a malfunction in the exhaust gas recycling system.

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 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： The linearity of response of a polarographic sensor, of the diffusion-limited current type, having a solid electrolyte (1) and being particularly adapted for measuring oxygen content in exhaust gases from combustion processes, is improved by providing the anode (2b) of the sensor's first, measuring cell with a constant, internal supply of reference oxygen. Preventing the oxygen concentration at the anode (2b) from fluctuating eliminates a non-linearity which would otherwise occur in the plot of oxygen concentration versus diffusion-limited current, as the fuel/air ratio of the mixture being combusted passes 1.The oxygen supply takes the form of a second, pumping cell (3a,3b) which can utilize the same solid electrolyte layer (1) as the first cell, and which pumps oxygen ions across the electrolyte to the second cell's anode (3b), where they become oxygen molecules and are directed through a duct (8) to the measuring cell's anode (2b).Excessive pressure in the duct (8) is prevented by providing small pores (10) in the surrounding glass cover (9) for outward diffusion of excess oxygen. A constant voltage is applied to both cells.

摘要： An apparatus is proposed for controlling the exhaust recirculation rate in an internal combustion engine, in particular an engine with auto-ignition, which includes preferably one mixture valve in the area of the discharge opening of the exhaust recirculation line and which is characterized in that the control is accomplished via the mixture valve position ahead of the inlet valves in accordance with the concentration of at least one component of the air-exhaust gas mixture and/or at least one component of the exhaust gas. Thus it is possible to operate the engine with a relatively emission-free exhaust. An exhaust gas reservoir is further provided, with which peaks in the exhaust gas concentration due to a dynamic driving mode can be intercepted. Finally, it is also proposed that the exhaust recirculation be realized solely via a pressure, which can be controlled in open-loop or closed-loop fashion, in the exhaust line by means of a valve.

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 improve the response speed of an electrochemical oxygen sensor, particularly for automotive use, to sense the oxygen content in exhaust gases, and which can be operative either as a polarographic sensor (requiring application of a voltage thereto), or as a potentiometric sensor (having one catalytically active electrode and another which is less catalytically active), an elongated insulating carrier plate (29), for example of a ceramic, has layer electrodes (30, 31) applied to one major surface thereof and a layer of solid electrolyte material (32) over the electrodes, so that the electrodes will be embedded in the solid electrolyte material. The carrier plate (29) is of a material pervious to oxygen molecules. A gas-impervious insulating cover (33), for example of a ceramic glass, covers the layer of solid electrolyte material (32). A heating element (34) protected by a protective cover (35), for example of aluminum oxide, can be applied against the gas-impervious cover layer (33).
