Patent number: 10926625Abstract: A tank system of a motor vehicle includes a volume-modifying element, which is provided in the interior of the fuel tank at least substantially above the liquid level and which is designed as a deformable bag, which forms a compensation volume connected to the environment, and includes a valve assembly, which closes under the control of a float during the filling of the fuel tank and thus brings about a maximum fill level in the fuel tank. A measure is provided for eliminating an effect of the volume-modifying element on the maximum fill level height. This measure can be that the volume-modifying element is arranged in the fuel tank such that, when the vehicle is standing on a horizontal surface, the top side of the volume-modifying element is not significantly above the fuel fill level at which the valve assembly closes in the vertical axis direction.Type: GrantFiled: November 2, 2018Date of Patent: February 23, 2021Assignee: Bayerische Motoren Werke AktiengesellschaftInventors: Emmanuel Arras, Markus Brater, Martin Bauer

Patent number: 10899223Abstract: A method for testing the tightness of a fuel supply system of a motor vehicle is provided. The fuel supply system includes a volume-changing element provided in the fuel tank, the volume of which volume-changing element is in contact with the environment. The fuel tank is customarily sealed off against the environment by way of a valve unit. For testing the tightness, a differential pressure with respect to environment is generated in the tank by way of a gas conveying device, sequentially and thus not simultaneously, the volume-changing element being sealed off against the environment, and the volume-changing element not being sealed off against the environment, a differential pressure with respect to environmental pressure is generated in the volume-changing element or in the tank.Type: GrantFiled: April 27, 2018Date of Patent: January 26, 2021Assignee: Bayerische Motoren Werke AktiengesellschaftInventors: Emmanuel Arras, Markus Huber

Publication number: 20200406745Abstract: A fuel tank for receiving a fluid in a motor vehicle. The fuel tank includes an outer wall forming an internal space for receiving the fluid. At least one volume element is arranged in the internal space for receiving air, and an opening that is a gas-guiding line between the volume element and the environment of the tank is for changing the volume of the volume element. The at least one volume element is formed at least partially as bellows.Type: ApplicationFiled: February 26, 2019Publication date: December 31, 2020Inventors: Emmanuel ARRAS, Manfred BIGALKE, Axel FROHWEIN, Markus HUBER, Attila FARKAS, Tim WALTER, Daniel HARMS, Gernot WEISS, Theodor OSSEGE, Jorg KOITH, Christoph MEHREN, Roman BOUFFIER

Patent number: 10675967Abstract: A tank system of a motor vehicle includes a volume modifying element, having a compensation volume, which is provided in the inner chamber of the fuel tank and which is used to equalize the vapor pressure. The compensation volume is connected to the surrounding area. The only connection between the volume modifying element and the surrounding area is formed by a storage unit of the gaseous fuel components and the inner chamber of the fuel tank is connected to the surrounding area by a valve unit. The valve unit is normally open when filling the fuel tank and when exceeding or falling below the pressure limits in the inner chamber of the tank, and is otherwise closed. The storage unit is connected to the valve unit.Type: GrantFiled: December 8, 2016Date of Patent: June 9, 2020Assignee: Bayerische Motoren Werke AktiengesellschaftInventors: Emmanuel Arras, Jutta Pribil, Markus Huber

Publication number: 20200139809Abstract: The invention relates to a tank, in particular a fuel tank, for receiving a liquid in a motor vehicle, comprising an outer wall that forms an internal space for receiving the liquid, at least one volume element situated in the internal space for receiving gas, in particular air, a gas-guiding line between the volume element and the surroundings of the tank for changing the volume of the volume element, and at least one stabilizing assembly for minimizing stresses at kinks of the volume element when evacuating the volume element.Type: ApplicationFiled: June 12, 2018Publication date: May 7, 2020Inventors: Daniel HARMS, Gernot WEISS, Roman BOUFFIER, Emmanuel ARRAS, Markus HUBER, Axel FROHWEIN, Attila FARKAS

Patent number: 10626826Abstract: A method for checking the tightness of a fuel supply system of a motor vehicle is provided. The fuel supply system includes a volume-changing element, which is provided in the fuel tank and the volume of which is connected to the environment. The fuel tank is typically closed off from the environment by way of a valve unit. For tightness testing, a differential pressure with respect to the environment is produced in the tank interior by way of a gas-conveying device while the volume change element is connected to the environment. The differential pressure is held by switching a suitable shut-off valve and is monitored over a certain time span or checked after a certain time span. Sufficient tightness of the fuel supply system is inferred if the differential pressure still exceeds a certain threshold value after the time span.Type: GrantFiled: April 27, 2018Date of Patent: April 21, 2020Assignee: Bayerische Motoren Werke AktiengesellschaftInventors: Emmanuel Arras, Markus Huber

Patent number: 10100783Abstract: A filter arrangement of a vehicle includes a filter, preferably an active carbon filter, a sprung suspension for the vibrational mounting of the filter in the vehicle, a sensor unit for determining a variable corresponding to the current weight of the filter from a vibrational movement of the filter, and an analyzing unit for calculating a filling degree of the filter from the filter weight determined, taking the empty weight of the filter into account. The filter is suspended such that the filter can vibrate about a rotational axis fixed to the vehicle.Type: GrantFiled: February 7, 2017Date of Patent: October 16, 2018Assignee: Bayerische Motoren Werke AktiengesellschaftInventor: Emmanuel Arras
