Abstract: A method of controlling the fuel air mixture of an internal combustion engine following a cold restart includes determining a control parameter based on the value of current coolant temperature at time of current engine start, the value of coolant temperature at time of the previous engine start, a calibratable reference temperature, the total accumulated fuel mass injected during previous engine run time, the time the engine was off before the restart, and the time the engine was run after previous start. The method also includes controlling the fuel air mixture based on said control parameter.

Abstract: A damper for fittings for furniture or household appliances has a housing in which a piston connected to a piston rod is guided in a linearly displaceable manner, the piston dividing an interior space in the housing into two chambers, wherein at least one flow channel is formed on or in the piston, which flow channel connects the two chambers to one another, wherein a throttle element is provided, which, in a damping position, keeps the cross-section of the at least one flow channel small when the piston moves in a first direction in order to generate high damping forces, and when the piston moves in the second direction opposite to the first direction, increases the cross-section of the at least one flow channel for reducing the damping forces by a movement of the throttle element.

Abstract: A method is presented for diagnosing a particulate matter sensing system, where the system includes a sensing element having two electrodes spaced from one another. The method determining at a first time during a cool-down event a first sensing element temperature and a resistance of the sensing element, and determining at a later second time during the cool-down event a second sensing element temperature and the resistance of the sensing element. The method further includes calculating a predicted sensing element resistance at the second sensing element temperature, based on the first sensing element temperature, the resistance of the sensing element determined at the first time, and a predetermined model of the resistance vs. temperature characteristics of the sensing element. A fault condition for the system may be indicated based on a comparison of the predicted sensing element resistance at the second sensing element temperature and a measured sensing element resistance.

Abstract: The invention relates to a damper (1) for furniture, especially hinges, comprising a housing (2) in which a piston (8) is connected to a piston rod (3) and can be displaced. A fluid flows through at least one flow channel (11) on or in the piston (8) during a movement of the piston (8) inside the housing (2).

Abstract: The invention relates to a damper (1, 1?) for furniture, especially hinges, comprising a housing (2, 2?) in which a piston (8, 8?) is connected to a piston rod (3, 3?) and can be displaced. A fluid flows through at least one flow channel (11, 11?) on or in the piston (8, 8?) during a movement of the piston (8, 8?) inside the housing (2, 2?), the movement of the piston (8, 8?) resulting in a different damping power in different directions. The cross-section of the flow channel can be modified in some sections on at least one groove (20, 20?) by moving a plate (12, 12?) relative to the piston (8, 8?). On the at least one groove (20, 20?), a substantially funnel-shaped outlet (22, 22?) and/or the groove (20?) have a section which is arranged at an angle to the radial direction to avoid cavitation.

Abstract: A drawer can be displaced relative to a basic furniture structure, via a pull-out guide. The drawer has, on the opposite sides, in each case at least one gearwheel which meshes with a rack, secured on the basic furniture structure, and is coupled to a gearwheel on the opposite side. The racks can be extended in length in each case via a pivotable lever, in order to ensure that the drawer is also guided by the gearwheels in the pulled-out position. A pivotable lever can be disengaged from the meshing gearwheel in order for it to be possible to correct skewed positioning of the drawer. This ensures that the drawer is guided by the gearwheels over its entire displacement path.

Abstract: A forage harvester includes feed rolls operable to convey crop to a crop cutter drum. The forage harvester is provided with a control arranged to produce a controller output signal based upon a sensed number of rotations of the crop cutter drum or the feed rolls. The controller output signal operates such that a difference between an actual relation between the feed roll and cutter drum speeds and a nominal relation is at least reduced. The control is operable to produce the controller output signal independent from a detection of the speed of the feed rolls or the chopper drum. The speed of the feed rolls or chopper drum is hence controlled without feedback, but with an open loop. Thus, a sensor is saved and control oscillations are avoided.
