摘要： The invention is directed to a method for computing a fuel-metering signal for adjusting a pregiven lambda value for the composition of the air/fuel mixture of an internal combustion engine. In the method, a first signal is formed which represents the air quantity flowing into the engine and a second signal is formed on the basis of the first signal so that a first lambda desired value adjusts when using its second signal as a fuel-metering signal. Various additional second lambda desired values are formed as a function of operating parameters of the engine. A selection is made of those second lambda desired values having the highest priority and the fuel-metering signal is formed by weighting the second signal with the second lambda desired value of the highest priority.

摘要： The invention is directed to a method and arrangement for checking the operability of a vessel. Pressure is introduced into the vessel utilizing a pressure source having operating variables which vary during operation of the pressure source. These operating variables are detected while the pressure is introduced into the vessel and a conclusion as to a presence of a leak in the vessel is drawn from the operating variables. By utilizing the operating variables, a statement as precise as possible is provided as to the presence of the leak with as little additional equipment as possible.

摘要： A tank venting device for motor vehicles having an internal combustion engine supplied from a fuel tank. The device includes a filter housing, which is connectable to a venting stub of the fuel tank and includes an adsorption filter, whose air inlet is occupied by a shutoff valve and whose air outlet communicates with an intake tube of the engine, and an air feed pump and a diagnosis device. To improve the metering capability for the regeneration mixture aspirated from the filter to the intake tube of the engine, the air feed pump is disposed with a reversible feeding direction between the air outlet of the filter housing and the intake tube of the engine. The air feed pump is controlled in its feeding direction reversal via a multiposition control valve such that the filter housing is located on the intake side of the air feed pump for the duration of filter regeneration, and on the pressure side of the air feed pump for the duration of error diagnosis.

摘要： A method and a device are provided for operating a drive unit having an engine and a transmission, which make possible an improved shifting strategy. In a first operating state, the engine is operated using a first number of active cylinders. In a second operating state, the engine is operated using a second number of active cylinders. The first number is different from the second number. A gear ratio is set as a function of at least one operating variable of the drive unit. The gear ratio is also set as a function of the current or the attainable operating state of the engine with respect to the number of the active cylinders.
