  • Patent number: 9297717
    Abstract: In a venting system, in particular for a fuel tank of a motor vehicle, which has a sorption filter for temporarily storing fuel evaporating from the fuel tank and a fluid-conveying conveying device situated between the sorption filter and an air supply or an intake manifold of an internal combustion engine, according to the present system, the conveying device is a bidirectional conveying device which is switchable in a first conveying direction in the direction of the internal combustion engine for regenerating the sorption filter and in a second conveying direction in the direction of the sorption filter for carrying out a fuel tank leak diagnosis.

  • Patent number: 9212633
    Abstract: 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.

  • Publication number: 20140109882
    Abstract: 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.

  • Patent number: 8418525
    Abstract: A method for testing the operability of a tank shutoff valve of a fuel tank system which is controlled by valves includes performing defined triggering of the tank shutoff valve and simultaneous introduction of an overpressure or partial vacuum into the fuel tank system via a pressure source, and the operability of the tank shutoff valve is determined on the basis of a variable which characterizes the introduction of the overpressure or partial vacuum.

  • Patent number: 7963150
    Abstract: A method to test for a leak in a fuel tank system of a motor vehicle includes a fuel tank is cut off during the overrun by means of at least one cutoff device, and the pressure, which builds up in the fuel tank within a specifiable time interval is acquired; if a specifiable maximum pressure or a specifiable vacuum threshold is not achieved, said cutoff device is opened and closed again after a specifiable time period, and a vacuum is produced and acquired in a subsequent vacuum phase, and a parameter, which characterizes the leak tightness, is determined and evaluated from the vacuum achieved within a specifiable time period and the overpressure, which is achieved, and the test for a leak is concluded; if the specifiable maximum pressure is achieved, a parameter characterizing the leak tightness is determined from the acquired overpressure and the specifiable overpressure threshold and is compared with a specifiable reference value and for the case that the determined parameter is smaller than the reference
