摘要： A method for operating a tank leakage diagnosis device, especially of a motor vehicle, volatile fuel (to be degassed) being temporarily stored using an adsorption filter of known absorption capacity or absorption characteristics, and the adsorption filter being regenerated from time to time by purging, using fresh air, to avoid faulty measurements in the tank leakage diagnosis, in particular at elevated fuel degassing. It is provided that the adsorption filter be purged, and, in this context, the volatile fuel removed from the adsorption filter over a predefined time span be integrated, and from that, the loading of the adsorption filter with the volatile fuel, changing during the time span, is ascertained, from the absorption capacity and the absorption characteristics of the adsorption filter, as well as the integrated fuel quantity or the changing loading. The quantity of fuel to be degassed supplied to the adsorption filter from the fuel container in the time span is calculated, and, as a function of the calculated quantity of fuel supplied to the adsorption filter, an intervention is undertaken at the tank leakage diagnosis device.

摘要： A method for detecting errors in a motor vehicle engine cooling system is proposed according to the invention, in which an algorithm is used to not only detect an error in the cooling system, but to also determine whether the thermostat valve or the temperature sensor are defective. Differentiated error detection is achieved in that a second temperature model band is calculated for the case in which the thermostat remains in the opened state. A first temperature model band is calculated for the case in which the cooling system is in order. By comparing the course of the curve for the measured actual temperature with the two temperature model bands, a selective diagnosis can be carried out and determine whether the temperature sensor or the thermostat valve is defective. No additional hardware expenditures are required.

摘要： In a prior art method proposed for determining the outgassing of fuel, the outgassing at the ambient pressure is determined, and it is not taken into consideration that with the tank leakage diagnosis, a negative pressure exists inthe fuel tank. Since with negative pressure, more fuel gases out than with ambient pressure, too small of an outgassing is determined. With the tank leakage diagnosis, the fuel tank is evacuated at a diagnostic pressure and subsequently, a pressure increase is measured. From the trend of the pressure increase over the time, a leak is closed. Since the outgassing also affects a pressure increase, the measured total pressure increase must be corrected to the outgassing pressure increase. Since with the proposed method, the outgassing pressure increase is determined to be too small, frequently false reports can occur. The method of the present invention proposes to determine the outgassing at the same pressure that prevails with the tank leakage diagnosis in the fuel tank (1). A check valve (10) is regulated in a ventilation line, such that, in this manner a predetermined pressure corresponding to the diagnostic pressure in the fuel tank (1) is adjusted.

摘要： The invention relates to a method for detecting combustion misfires in a multi-cylinder internal combustion engine. Combustion misfires are detected from data for the rough running of individual cylinders via a comparison with threshold values at operating points stored in a characteristic field. These data are determined within the engine. The combustion misfire detection is suppressed below an rpm-dependent zero-load characteristic line. The zero-load characteristic line is continuously adapted to the actually present lowest load at corresponding rpm values during vehicle operation.

摘要： In the method of monitoring a cooling fluid circuit of an internal combustion engine with setting a first error signal if a deviation of an actual value of a temperature from a desired value of the temperature exceeds a predetermined amount, a second error signal is set, which indicates a possible lack of antifreeze if a starting temperature is below the freezing point of water, a first error signal was present, the first error signal is no longer present after a predetermined time which is a function of the engine starting temperature and a build-in energy balance exceeds a threshold which is a function of the engine starting temperature.

摘要： In a method and a device for leak testing of a vessel, e.g., a tank venting system of a motor vehicle, a leak-tightness measurement is performed by introducing a positive pressure or partial vacuum and detecting the variation over time of a positive pressure or partial vacuum in the vessel, and a reference measurement is performed using a reference leak. A conclusion is drawn as to the presence of a leak in the vessel by comparing the results of the leak-tightness measurement and the reference measurement. To avoid faulty diagnoses, the positive pressure or partial vacuum during the leak-tightness measurement and the reference measurement is detected by using a single pressure measuring device.
