    • To permit individual evaluation of the combustion processes in the respective cylinders (1a-d) of an internal combustion (IC) engine (2), individual optical pick-ups (3a-d; 4a-d) are coupled to the respective cylinders, the output signals either in optical or electrical form are conducted to separate pick-ups for individual evaluation or, alternatively, the output signals are combined and then again separated out by a steering circuit. Individual evaluation can be accomplished by locating light guide fibers from the sensors in a predetermined position with respect to opto-electrical transducers; by forming scanning windows, for example by a rotating disk (19, 20) rotating n in synchronism with the engine and permitting passage of light from the respective fibers of the light guides to respective pick-ups; or by combining the light outputs from the respective sensors (4) either optically by intermixing light guide fibers in a common cable (6'), or electrically in an equivalent OR-circuit (FIG. 8: R.sub.L) with subsequent correlation of the output signal with a specific cylinder by a scanning disk (FIG. 6: 20) with suitably placed openings (22a-d) therein, or an electrical time-multiplex steering circuit (FIG. 8: 30) operating in synchronism with rotation of the engine.
    • 为了对内燃(IC)发动机(2)的各汽缸(1a-d)中的燃烧过程进行单独评估,将各个光拾取器(3a-d; 4a-d)联接到相应气缸, 以光学或电气形式输出的信号被传送到用于单独评估的单独的拾取器,或者,输出信号被组合,然后由转向电路再次分离。 可以通过将来自传感器的光导纤维相对于光电换能器定位在预定位置来实现个体评估; 通过形成扫描窗口,例如通过与发动机同步旋转的旋转盘(19,20),并允许光从光导的各个光纤通过到相应的拾取器; 或者通过将光导纤维混合在公共电缆(6')中,或者在等效的或电路(图8:RL)中电耦合来分别来自各个传感器(4)的光输出, 通过其中具有适当放置的开口(22a-d)的扫描盘(图6:20)或具有与发动机的旋转同步运行的电气时间复用转向电路(图8:30)的具有特定气缸的信号 。

    • Disclosed is a method and device for regulating the preparation of fuel-and-air mixture in a carburetor, fuel injection system and the like of an internal combustion engine. The device includes an oxygen probe directly communicating with the combustion chamber of the engine. Periodically fluctuating output signal of the probe is applied to an averaging circuit which produces an average output signal over a predetermined number of engine cycles. The shape and length of the averaged output signal is indicative whether the mixture ratio is lean or rich. The averaging can be made by means of a lowpass filter, an integrator or at least one counter counting in response to the angular position of the crankshaft or the predetermined time intervals. When the probe output voltage has the form of a hump or bulge, its length or area is used for determining the actual .lambda. value in the rich range of ratios of the mixture.
    • 公开了一种用于调节内燃机的化油器,燃料喷射系统等中的燃料和空气混合物的制备的方法和装置。 该装置包括直接与发动机的燃烧室连通的氧探头。 探测器的周期性波动的输出信号被施加到在预定数量的发动机循环上产生平均输出信号的平均电路。 平均输出信号的形状和长度指示混合比是贫还是富。 可以通过低通滤波器,积分器或响应于曲轴的角位置或预定时间间隔对至少一个计数器进行平均。 当探头输出电压具有凸起或凸起的形式时,其长度或面积用于确定混合比的丰富范围内的实际λ值。
