摘要： A tank-venting arrangement for a motor vehicle includes a fuel tank KT having a HC (hydrocarbon)-sensor, an adsorption filter AF and a tank-venting valve TEV. If the HC-sensor annouces that fuel vapor above a pregiven concentration is present in the tank, then it is expected that a lambda correction in the lean direction is required when the tank-venting valve is opened. If such a correction is not determined, this shows that either the arrangement leaks or the tank-venting valve does not open correctly. For carrying out the mentioned testing method, this arrangement requires only a single additional sensor, namely, the HC-sensor mounted in the tank. The arrangement is therefore simpler than known arrangements and nonetheless permits carrying out a reliable method for checking the operability.

摘要： A method and an arrangement for carrying out the method are proposed whose fundamental concept is to perform a diagnosis of the heating device of an exhaust-gas probe, which emits a control signal for closed-loop controlling the air/fuel mixture of an internal combustion engine. The diagnosis is based on that the exhaust-gas probe is heated more rapidly because of the switching-in of the heating device than by mere heating by the exhaust gases which flow past the exhaust-gas probe. The heating device includes at least the probe heater, devices which supply the probe heater with the necessary heating power, and the supply leads therefor.

摘要： To permit operation of engines, particularly turbo-charged engines, at the maximum power level just short of causing engine knocking, and preventing engine knocking, temperatures in the engine are sensed and, if an excessive temperature signal is detected, for example excessive engine temperature, exhaust gas temperature, turbo-charged air, or turbo charger temperature, a fuel supply system, for example a fuel injection system, is controlled to enrich the mixture, for example by multiplying the fuel injection time by a factor as commanded by an additional control stage (26, 27, 30) which stores in a memory, such as a ROM (27), engine operating characteristic curves. In addition, spark retardation by a retarding angle (.alpha.1) can be commanded, the spark retardation in combination with enriching of the fuel-air mixture being less than without such enrichment, thus permitting operation of the engine at appropriate power and efficiency level without noticeably increasing fuel consumption in the course of continued operation of the engine.

摘要： A venting system for a fuel tank includes a sorption filter for temporarily storing fuel evaporating from the fuel tank and a delivery device arranged between the sorption filter and an air supply system of an internal combustion engine in a fluid-conducting manner. The internal combustion engine is a turbocharged engine with a turbocharger unit and a throttling device in the air supply system. The sorption filter is connected to the air supply system in a fluid-conducting manner by a first line at a first inlet point arranged upstream of the turbocharger unit and by a second line at a second inlet point arranged downstream of the throttling device. A tank venting valve is arranged in the second line, and the first line branches off from the second line upstream of the tank venting valve in the flow direction towards the second inlet point.

摘要： A method and an arrangement for monitoring a pressure sensor are suggested which determines a value representing the ambient pressure of an internal combustion engine. Furthermore, an index for the extent of the correction of the mixture composition via the mixture control system is determined and the supplied air mass is detected from the throttle flap angle and the intake manifold pressure. A fault in the determination of the ambient pressure is detected when the measured air mass deviates from the computed air mass and the correction of the mixture control system is less than a predetermined limit value and when, for an open throttle flap, intake manifold pressure and ambient pressure deviate impermissibly from each other.
