    摘要： To balance ozone sensors for the onboard diagnosis of a catalytic element which is arranged in a vehicle and is exposed to an ambient airstream, for breaking down ozone, predetermined enable conditions allowing the sensor balancing to be carried out are checked, and if the enable conditions are fulfilled the values of the output signals from the ozone sensors are recorded and compared with one another. This comparison gives a deviation value which is characteristic of the deviation between the two values, and the deviation value is used to decide whether sensor balancing is required and indeed possible. If sensor balancing is required and possible, the values of the output signals from the ozone sensors are compared with a threshold value and depending on the result of this comparison either an additive or a multiplicative correction of the values of the output signals is performed.

    摘要： The internal combustion engine has at least two partly separate exhaust systems in each of which are disposed a catalytic converter, and upstream thereof, a lambda probe. There is provided a secondary air pump and a number of individual secondary air lines, corresponding to the number of exhaust systems, for delivering secondary air to the respective exhaust systems. From the signal of at least one air mass meter, a value is determined for the total air mass flow introduced into the exhaust systems. In order to determine the air mass actually introduced into the individual exhaust systems, the output signals from the lambda probes in the exhaust systems are used to identify an uneven distribution of the air mass fed to the individual exhaust systems.

    摘要： Method for checking the conversion capacity of a catalytic element for converting ozone where the catalytic element is provided as a vehicle radiator with a catalytic coating and the method of checking uses ozone sensors upstream and downstream of the radiator. The check is only carried out if predetermined enable conditions are satisfied. Only then are the values emitted by the sensors recorded and compared with one another. A variable which represents an uncorrected value for the quality of the conversion capacity is derived from this comparison. This variable is weighted as a function of at least one operating parameter of the vehicle. The weighted variable is compared with a predetermined threshold value, and, if the threshold value is exceeded, it is concluded that the conversion capacity of the radiator is insufficient.

    摘要： During the starting of an internal combustion engine with fuel injection, so-called preliminary injections (I) are dispensed according to a certain preliminary injection strategy in order to build up a wall film in the cylinders and simultaneously provide an ignitable mixture for the initial combustion. To avoid a situation where the preliminary charges during the starting phase are too rich or too lean, different quantities of fuel are chosen for the preliminary injections (I), depending on the charges to be expected in the relevant cylinders.

    摘要： The tank venting system is evacuated by the negative pressure prevailing in the intake pipe of the internal combustion engine. A regression calculation, based on a physical model which simulates the pressure variation in the event of a leak in the tank venting system, on the basis of a gas mass flow flowing through an opening, supplies a parameter which describes the curve variation of the pressure during the test for gassing out fuel and during the diagnosis. The parameter contains the information about the leak area and takes into account external influences that interfere with the signal evaluation.
