    摘要: To modify engine operation and reduce the tendency of the engine to knock or ping, a knocking signal is generated which is representative of knocking intensity and/or frequency of knocking occurrence, and compared with a permissible knocking signal. The result of the comparison is utilized to change an operating parameter of the engine, for example by injecting a fluid, e.g. water, into the engine, changing charge pressure, for example of a turbocharger or the like. The permissible engine knock signal can be modified in accordance with an engine operating parameter, for example at low temperature, or low speed, the permissible knocking limit can be raised since the damaging effect of knocking at low temperature or low speed is less than under different operating conditions.

    摘要: A known control system for adjusting the lambda value of an internal combustion engine includes a corrective value ROM for transient operation wherein corrective values are stored for correcting the injection times for transient operation. In contrast thereto, the system according to the invention includes a corrective base value ROM 30, an adaptation value RAM 35 and an adaptation unit 34. The values from the corrective base value ROM are not utilized directly for correcting injection times; instead, these values serve as corrective base values which only become adapted corrective values by means of multiplication with adaptation values. The adaptation unit adapts the adaptation values in the adaptation value RAM. For this purpose, the adaptation unit determines the lambda value control deviations during a transient operation. If a control deviation is established, then the adaptation unit supplies a change value which is so dimensioned that an adaptation value, which is present for the monitored transient operation, is so corrected that for the next occurrence of a transient operation having the same initial operating conditions, only a smaller control deviation should occur and in the ideal case no such control deviation should occur. The control system according to the invention makes it possible to obtain very low toxic gas quantities also during a transient operation.

    摘要: 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.

    摘要: To determine proper operation of a combustion sensor, and to normalize the output signals derived from a pick-up having a window exposed to the combustion chamber (10) by compensating for soiling, contamination, and loss of transmissivity of the window due to combustion residue, soot, or the like, a reference light source is provided introducing reference light of a predetermined level to the pick-up, for example when no light is generated due to combustoin events. In an internal combustion (IC) engine, the reference light can be energized during stopped condition of the engine, or during portions of the stroke of the engine when no combustion event takes place. Output signals from the pick-up are applied to a variable amplification factor amplifier, the amplification factor of which is first calibrated with a clean light source, and then continuously recalibrated or normalized with respect to its original calibration by changing the amplification factor in accordance with electrical signals derived from sensing of the reference light, so that the actual sensing light will be normalized with respect to the reference. The calibration, itself, can be variable and account for external factors, such as aging or decrease of light output of the light source. The reference light can be introduced by an externally operated incandescent filament or by shining light into a portion of a tubular housing, for example through a glass light guide, and reflecting the reference light into the sensing window which also senses light due to combustion.

    摘要: The internal combustion engine has at least one combustion chamber, an inlet conduit leading to it, and an adjustable means for varying flows of a medium, such as air or a fuel-air mixture, flowing into the combustion chamber for the sake of an optimized acceleration of curves defined by the process of combustion, so that economical engine operation is attained while producing as little in the way of toxic exhaust gas components as possible. An adjusting motor acting upon the means is controlled by a regulator, which is connected via a comparator with a set-point value transducer and an actual-value transducer. The actual-value transducer includes an optoelectric sensor connected to the combustion chamber for measuring the curves of combustion. The set-point value transducer indicates a set-point value for optimal curves of combustion, and the regulator, via the adjustable means, reduces any difference that may exist between the set-point value and the actual value.

    摘要: An apparatus is proposed for detecting operating characteristics of an internal combustion engine. It has an optical sensor whose output signal is delivered to an amplifier with a variable transmission behavior. As a result, it is possible to have either a stepped or a continuous adaptation of the sensor sensitivity to various operational points of the engine. It is particularly proposed that the amplification for the measurement signal be selected to be high in the case of an opto-electrical combustion chamber observation in a low load range, while it is selected to be low in a high load range, so that relatively equalized measurement results are available for use.
