摘要:
A method for monitoring the leak tightness of a fuel tank system is provided, the fuel tank system being provided for supplying fuel to a supercharged internal combustion engine. A pressure accumulator is filled from the supercharged intake manifold area of the internal combustion engine. The pressure from the pressure accumulator is transferred to the fuel tank system, which includes in particular the fuel tank and, if necessary, an activated carbon filter. The pressure curve in the closed fuel tank system is observed. A leak in the fuel tank system may be inferred on the basis of the pressure curve, if necessary.

The invention relates to a method and system for diagnosing communication connections in a communication system. The invention enables the provision of a plurality of first diagnosis units and at least one second diagnosis unit, wherein the first and second diagnosis units each are assigned to a communication connection of the communication system and are configured for determining a value of a diagnosis variable of the respectively assigned communication connections, and provides for determining a value of at least one diagnosis variable by each of the first diagnosis units, determining a value of at least one diagnosis variable by the at least one second diagnosis unit, transferring the values determined by the first diagnosis units to an evaluation unit, statistically evaluating the transferred values by the evaluation unit, and diagnosing the values determined by the at least one second diagnosis unit depending on the statistical evaluation by the evaluation unit.
摘要:
A device for selectively regenerating and performing tank leakage diagnosis of a tank ventilation system has a sorption filter and a pump. The sorption filter is configured to temporarily store fuel evaporating from a fuel tank. The pump is arranged at a fresh-air side of the sorption filter and is connected in fluid-conducting fashion to the sorption filter. The pump is configured to generate a fluid flow to regenerate the sorption filter.

摘要:
An input/output module (1) with a terminal unit (2) for connection of sensors or actuators with an electronic unit (3) and with a bus connection element (4). The terminal unit (2) has at least one input/output (5) located in a surface thereof and the terminal unit is connected by the electronic unit (3) to the bus connection element (4). To replace the electronic unit (3), the terminal unit (2) can be removed from the electronic unit (3) without the need to remove lines (6) connected to the inputs/outputs (5). The terminal unit (2) is able to be mounted to the electronic unit (3) in each of two positions, the input/output (5) in the two positions lying in planes that are offset relative to each other by 90.degree..
