摘要： The invention is directed to a method for obtaining a value for evaluating the performance loss of a catalytic converter with the aid of a forward signal of a forward gas probe mounted forward of the catalytic converter and a rearward signal of a rearward gas probe mounted rearward of the catalytic converter, the catalytic converter being connected to an internal combustion engine. The method includes the steps of: carrying out the method during the steady-state operation of the engine; multiplying the forward signal and the rearward signal with each other to form a plurality of products; averaging the products over a plurality of oscillations of the forward signal to obtain a mean value; and, utilizing the mean value as a value for evaluating the performance loss of the catalytic converter. This correlation method can be varied in different ways and especially in that the forward-probe signal is correlated without or with phase shift with the rearward-probe signal. A cross-correlation factor or the real or imaginary component of an orthogonal correlation or other correlation values are obtained in dependence upon the nature of the correlation. These correlation values are used for evaluating the performance loss of the catalytic converter. The evaluation of the performance loss of the catalytic converter with the aid of these correlation values is very significantly more reliable than the evaluation with the aid of amplitudes or amplitude mean values of the probe signals.

摘要： The invention relates to a method and an arrangement for checking the operability of an electric heater in motor vehicles and especially the heater of an oxygen probe which is mounted in the exhaust gas channel of an internal combustion engine. It is necessary to determine the temperature-dependent electrical resistance and the temperature of the oxygen probe heater for a precise evaluation of the operational state of the oxygen probe heater. The basic principle of the invention is based upon the consideration that the measurement of the electrical resistance of the oxygen probe heater is then carried out when the oxygen probe heater has cooled down to the ambient temperature. Whether this cool down has taken place can be determined in various ways in accordance with the invention, for example, from the cool down of the engine block or by a comparison of the engine block temperature to the intake-air temperature. The operating state of the oxygen probe heater so determined is displayed to the driver by the activation of a corresponding control device and/or, if required, read into a fault memory.

摘要： A method is introduced for detecting combustion misfires on the basis of the time-dependent course of the rotational movement of a transducer wheel, which is coupled to the crankshaft of an internal combustion engine. In this method, the segment times, in which predetermined segments of the transducer wheel pass a sensor, are detected and processed to a measure for the rough running of the internal combustion engine. A conclusion as to misfires is drawn from the behavior of the measure. The measure for the rough running is formed by digital filtering of segment times with predetermined filter coefficients.

摘要： The invention is directed to a method of detecting disturbances of the crankshaft rpm for an internal combustion engine which are caused by an empty tank. Uneven-running values (LU) of the engine are detected which are distributed in bands of values and the spacing between the bands of uneven-running values (LU) is computed. A quantity of the engine is detected which is relevant to the exhaust gas of the engine. A check is then made to determine whether the computed band spacing is less than a pregiven threshold spacing and whether the exhaust-gas relevant quantity lies within a pregiven threshold value interval and, if so, this data is utilized as an indication that the disturbances of the crankshaft rpm are caused by an empty tank.

摘要： A first signal imaging nonuniformities in the rotational movement of the crankshaft is provided and corrective values are formed and successively changed for each cylinder individually and specifically for each load/rpm range of a plurality of load/rpm ranges until a predetermined condition is satisfied. The corrective value of the first one of the load/rpm ranges wherein the predetermined condition is satisfied is logically coupled to the first signal also in the remaining ones of said the ranges so long until the condition is also satisfied in the remaining ones of the ranges to thereby form a second signal less influenced by the nonuniformities than the first signal. A misfire is then detected when the second signal crosses over a reference value.

摘要： The invention is directed to a method for detecting combustion misfires in an internal combustion engine having a crankshaft and a transducer wheel coupled to the crankshaft and a sensor. The combustion misfires are detected on the basis of a time-dependent trace of the rotational movement of the transducer wheel and the transducer wheel has predetermined segments which pass the sensor. In the method, a sensor is utilized to detect segment times in which the segments pass the sensor so that the sensor produces a sensor signal representing the segment times. The sensor signal is applied as an input signal to first and second lowpass filters mutually connected in parallel thereby obtaining first and second output signals which react with different speeds to changes in the input signal. The difference between the first and second output signals is formed and a measure is, in turn, formed for the changes of the difference. The measure is compared to a threshold value and a movement of the measure above the threshold value is evaluated as a misfire.

摘要： The invention is directed to a method for detecting combustion misfires on the basis of a first complex input feature signal wherein the nonuniformity of the rotational movement (on the basis of rpm or segment times) of the internal combustion engine is mapped within a first order defined by a rotation of the crankshaft through an angle of 720.degree./k wherein k=1. The input feature signal serves as a feature signal to detect recurring misfires and functions as a feature signal to detect sporadic misfires. The complex input signal is defined by a magnitude and a phase angle which vary as a function of time. The presence of a misfire is detected from the magnitude and the affected cylinder is determined from the phase angle.
