Abstract: A method of operating a motorized flap arrangement of a motor vehicle, the flap arrangement including a flap, configured to be swiveled about a swivel axis, a drive arrangement, a drive controller, configured to control the drive arrangement, and a motion sensor arrangement, the sensor values determined by the motion sensor arrangement are checked for fulfillment of a specified actuation criterion, upon which an actuation effect manually exerted on the flap is deemed to be detected and the drive arrangement is controlled by the drive controller for motorized adjustment of the flap. The motion sensor arrangement arranged on a section of the flap facing away from the swivel axis. The actuation criterion is defined in such a way that the actuation criterion is fulfilled by a torque introduced into the flap before exceeding a breakaway torque of the flap kinematics.

Abstract: Methods and systems are provided for a cooling arrangement. In one example, a system comprises a separator arranged in a block coolant jacket. The separator fluidly separates an upper portion of the block coolant jacket from a lower portion of the block coolant jacket.

Abstract: Methods and systems are provided for a compressed natural gas fuel rail. In one example, a system comprises a device having a first volume for housing compressed natural gas and a second volume for housing lubricant, the first and second volumes arranged in a single housing and separated by a barrier. Lubricant flow from the second volume to the first volume may be adjusted by adjusting a pressure of the second volume so that a pressure difference between the second and first volumes is increased to increase lubricant flow or decreased to decrease lubricant flow.

Abstract: Methods and systems are provided for a cooling system valve comprising a fusible insert and a heating element coupled to the insert. In one example, in response to an increase in coolant temperature to above a first threshold temperature, a movable element of the cooling system valve may be actuated to a fully open position and in response to an increase in coolant temperature to above a second threshold temperature with the movable element in a fully open position, electric current may be routed through the heating element to heat and melt the fusible insert. By melting the fusible portion, coolant may flow through an opening created in the movable element.

Abstract: A device for supplying lubricant for a fuel injection nozzle for injecting compressed natural gas (CNG) into an internal combustion engine is provided. The device includes a lubricant reservoir for supplying lubricant and having a feed pressure supply apparatus for applying a feed pressure to lubricant which is stored in the lubricant reservoir, where a feed pressure valve for setting the feed pressure is provided between the feed pressure supply apparatus and the lubricant reservoir, and a lubricant metering valve for metering the lubricant supply is provided between the lubricant reservoir and the fuel injection nozzle, where the lubricant is fed to the lubricant reservoir from an oil gallery of the internal combustion engine.

Abstract: Systems and methods for reducing inertial forces of a reciprocating piston internal combustion engine are described. The systems and methods may provide for counterweights in a form of pistons in cylinders that are moved via electromagnets. The counterweights may be moved at a frequency that corresponds to engine speed via an alternating current.
