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： 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.
摘要翻译：光学耦合到内燃机（IC）发动机的燃烧室（10'）的传感器（10）通过使传感器受到机械冲击或振动而保持没有污染或污垢沉积物等。发动机本身通过控制发动机在受控的爆震条件下由单稳态触发器（FF）（18）设定的预定时间段来实现机械冲击或振动，燃烧室内的冲击波引起剥落脱落或掉落污染沉积物。可以通过在点火系统（19）的过度火花提前的方向上进一步控制点火正时或者超越已经存在于发动机上的爆震抑制系统来获得控制爆震。传感器的污染程度可以例如通过将在发动机曲轴的预定旋转角度上接收到的光积分并将该旋转与供给到发动机用于燃烧的燃料量进行比较来确定，例如通过与燃料喷射脉冲的定时等。

To accomplish this, a heating system including a control mechanism is provided for the oxygen sensor which adjusts the temperature of the oxygen sensor by controlling the output of a heater during the operation of the internal combustion engine according to characteristic engine operating conditions which have an effect on the temperature of the oxygen sensor, the most significant of which is engine load status. These conditions are sensed as a quantity by probes located so as to measure such operating conditions and send a signal to the control mechanism and its sensor heater.

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.
