Patent number: 11035306Abstract: A control device is provided for a cooling liquid injection system for an internal combustion engine of a motor vehicle. The cooling liquid injection system includes at least two activatable injectors for introducing a cooling liquid into the internal combustion engine, which injectors can be controlled by the control device. The injectors can be supplied with cooling liquid by way of a common rail, and the control device is designed to receive an inclination variable, which characterizes an inclination of the rail, to determine an activation response for the injectors in dependence on the inclination variable, and to activate the injectors using the determined activation response in order to empty or fill the rail.Type: GrantFiled: December 5, 2018Date of Patent: June 15, 2021Assignee: Bayerische Motoren Werke AktiengesellschaftInventors: Martin Boehm, Stefan Detterbeck, Bjoern Hussmann

Patent number: 10737594Abstract: The invention relates to a foot prop adapted to be attached to a child safety seat, comprising an elongate component, comprising an upper portion and a lower portion, wherein the lower portion is slidable relative to the upper portion in longitudinal direction of the elongate component. The foot prop is configured such that a force applied in the longitudinal direction causes the lower portion to automatically move away from the upper portion whenever the force exceeds a predetermined threshold, so that the length of the elongate component is increased; and the foot prop is configured such that the lower and the upper portion are releasably blocked against relative movement towards one another. The invention further relates to a seat base and a child safety seat comprising a foot prop.Type: GrantFiled: September 13, 2018Date of Patent: August 11, 2020Assignee: Britax Römer Kindersicherheit GmbHInventors: Martin Böhm, Martin Haas

Patent number: 8973550Abstract: An oil supply device for a crankcase of an internal combustion engine feeds oil from a reservoir to a main oil duct of the crankcase. A filter switching device allows a selection from a plurality of oil filter units in the flow path of the oil to be selectively connected into the oil flow path, to set a proportion of the oil filter units to active and a proportion of the oil filter units to passive. A switching unit switches between the active and passive states and opens up a pressurized oil flow path to the active oil filter unit(s) and also a drainage flow path between the passive oil filter unit(s) and a drainage duct. An evacuation device drains or evacuates oil from the drainage duct which has accumulated at the passive oil filter unit(s).Type: GrantFiled: January 17, 2012Date of Patent: March 10, 2015Assignee: MAN Truck & Bus AGInventors: Jens Tuerk, Franco Zemczak, Mark Zimmermann, Martin Boehm
