摘要： In a method and device for monitoring a secondary-air system, a first value is determined which characterizes the secondary air stream blown by the secondary-air system into the exhaust-gas channel of an internal combustion engine. On the basis of this first value, the functioning of the secondary-air system is judged. If the first value lies within a predeterminable interval, it is concluded that the secondary-air system is operating properly. If the first value, on the other hand, lies outside of this predeterminable interval, it is concluded that a malfunction is present. The first value is determined from a second value which characterizes the stream of air fed to the internal combustion engine, from the air/fuel ratio of the mixture drawn in by the internal combustion engine, and from the air/fuel ratio prevailing in the exhaust-gas channel downstream of the place of introduction of the secondary-air line.

摘要： In a method for adjusting air and fuel masses for a multi-cylinder internal combustion engine with individual injection for each cylinder, the fuel mass for each injection operation is calculated taking into account the probable intake-pipe pressure during the opening time of the inlet valve. After a change of the accelerator pedal, the throttle flap is only adjusted when the fuel masses decisive for the new throttle-flap position have been calculated and substantially ejected. By virtue of the fact that fuel masses to be injected are not calculated taking into account the current air mass flow but taking into account the intake-pipe pressure, which is decisive in the induction operation, and that a change in the actuation of the throttle flap, which would lead to a change in the intake-pipe pressure not taken into account in the calculation of the injection quantity, is only permitted again after a recalculation, an optimum ratio between fuel mass and air mass per charge for the purpose of obtaining a specified value for the air/fuel ratio is always obtained, even in non-steady-state conditions of an internal combustion engine. Apart from the future intake-pipe pressure, account is also taken in the calculation of the fuel mass to be ejected of how much fuel passes into a wall film or is released from the latter.

摘要： The device for determining load in internal combustion engines includes a pressure sensor connected with a combustion chamber of an internal combustion engine which produces an output signal depending on a combustion chamber pressure, a crankshaft angle sensor for detection of a crankshaft angle of the internal combustion engine and a processor for determining a load of the engine from relative values of the output signal of the pressure sensor at predetermined crankshaft angles. The processor includes a device for determining the load from a pressure difference between combustion chamber pressures measured at two different predetermined crankshaft angles (x1, x2) or from two integrated pressure values. The integrated relative pressure values are obtained by integration of a pressure-proportional output signal of the pressure sensor between two different predetermined crankshaft angles.

摘要： A transmitter wheel is used for example to detect speed changes of an internal combustion engine with high precision in order to calculate a running imbalance value from them. A transmitter wheel of this kind has for example three segments, which are ideally the same length, but in reality usually have lengths which differ slightly from one another. In order to prevent measurement errors which are caused by this, it is known to determine the actual lengths by means of an adaption process. The device according to the invention is embodied such that for each segment, it has a plurality of adaption filters to detect different adaption values for different speed ranges. It has namely turned out that in different speed ranges, different lengths are measured, which is an error that must be compensated for since the length of a segment is in fact actually constant.

摘要： A method for learning control and precontrol for adjusting the lambda value for the air/fuel mixture to be metered to an internal combustion engine 11 compares a large comparison value with a small comparison value with the large comparison value being formed by averaging of adaptation factors for large precontrol values and the small comparison value being formed by averaging of adaptation factors for small precontrol values. Whenever the large comparison value is smaller than the small comparison value, a global summand is incremented by a correction value, otherwise it is decremented. An apparatus operating according to this method has the advantage that disturbing influences which act additively on the injection time are compensated with great accuracy.

摘要： An adaptation value memory is used for a learning control method having precontrol for an internal combustion engine and a corresponding apparatus. The adaptation value memory has a predetermined number of support points which are addressable via data records of values of address operating values. A learning operation is initiated if a support point region is left during operation of the internal combustion engine and if steady state operation was present therebefore. The adaptation value of the above-mentioned support point is changed by the learning operation when a control means issues an actuating variable which deviates from a desired actuating variable. The actuating variable deviation is not applied in full strength, instead, it is applied attenuated to change the old adaptation value. This is performed by means of an attenuation means which, as main function groups, has a learning intensity table 26, a counter read memory 27 and a counter difference table 28. The counter read memory stores the number of already completed learning cases for each support point. The learning intensity table issues a learning intensity value in dependence upon counter reading and the value of the actuating variable deviation. The counter reading is then changed, that is, for small actuating variable deviations, each time by "1", so long as a maximum value has not yet been reached.

摘要： Engine knock sensor signals are amplified, band-pass filtered and rectified and then a sequence of integrated signal peak values are compared with reference signals relating to a typical engine knock signal. If the deviation of the integration values or peak values or their sum over a measurement period differs by less than a predetermined amount from the corresponding reference values, a knock indication is produced. The initial integration or peak value may be given less weight than those that follow. The knock sensor may be an engine block sound sensor, or a combustion chamber light, pressure or iron current sensor. Additional criteria, such as the interval between null transitions or signal maxima or the number of them in a measuring period may be used to inhibit a knock indication in case the main processing should occasionally provide an anomalous knock signal, but this precaution is not sufficiently needed to warrant its inclusion in simplified systems.

摘要： A misfire detection system for an internal combustion engine is disclosed with the system being used to evaluate wheel rpm fluctuations. This system detects a rough roadway over which the misfire detection is to be inhibited. This detection is made with the aid of wheel rpm signals; that is, signals as they are present for all motor vehicles equipped with anti-locking brake systems and for motor vehicles which utilize the wheel rpm signal for determining road speed. In motor vehicles of this kind, the advantage is provided that the wheel rpm signal has a double use. The advantage is provided that a reliable detection of a rough roadway is possible for all motor vehicles independently of whether wheel rpm signals are used for inhibiting the misfire detection or not.
