摘要： The invention is directed to a tensioning arrangement for saw chains of motor-driven chain saws which include a device for longitudinally displacing the guide bar. The clamped guide bar is released so that the adjusting arrangement can be actuated for the longitudinal displacement of the guide bar. By rotating a disc having a spiral slot, a slide piece, which is coupled to the guide bar, is displaced in the longitudinal direction. Assembly is simplified and handling facilitated when the tension in the saw chain is adjusted. This is achieved by making the slide piece on the spiral disc so that it is not released therefrom but instead is held so as to be rotationally and longitudinally displaceable. The slide piece is fixedly connected to the guide bar by using appropriate attachment devices.

摘要： The invention is directed to a tensioning arrangement for a saw chain of a motor-driven chain saw. The saw chain runs on a guide bar mounted on the motor housing of the chain saw. The tensioning arrangement includes a rotatable disc having a spirally-shaped guide slot in which a lug of a slide piece engages. The longitudinal displacement of the guide bar is provided by rotating the disc. The guide slot in the disc extends over a rotational angle of at least 270.degree.. A still lesser slope of the guide slot is provided with a rotational angle in the range of 360.degree. to 450.degree.. The tensioning arrangement is especially suitable for adjusting the guide bar in motor-driven chain saws thereby adjusting the tension in the saw chain.

摘要： The invention directed to a portable handheld drilling apparatus for receiving and driving a drill which can encounter a drilling resistance during a drilling operation thereby causing the drilling apparatus to undergo an unwanted rotational movement. The drilling apparatus of the invention includes: a handle for holding by an operator while performing the drilling operation; a drive motor; a transmission for driving the drill; a centrifugal clutch assembly mounted between the drive motor and the transmission; a brake device movable between an inactive position and a braking position; a trigger lever movable between a first position wherein the trigger lever is at rest and a second position; the trigger lever being operatively connected to the brake device so as to trip the brake device into the braking position when the trigger lever moves from the first position into the second position; and, an actuating device for acting upon the trigger lever to cause the trigger lever to move into the second position when the unwanted rotational movement exceeds a pregiven limit value.

摘要： An actuating device for a decompression valve of an internal combustion engine with a cable starter, wherein the decompression valve is positioned within the cylinder of the internal combustion engine and comprises a valve member biased into its closed position, has a transmission lever having a longitudinal extension and being rotatable about its longitudinal axis. The transmission lever has a first and a second end. A cable drum for receiving the starter cable of the cable starter is provided. The cable drum has an axis of rotation about which the cable drum is rotated when the starter cable is pulled. The longitudinal axis of the transmission lever is perpendicular to the axis of rotation of the cable drum and spaced from the rotational plane of the cable drum. The cable drum entrains the first end of the transmission lever in the direction of rotation and thereby rotates the transmission lever about its longitudinal axis such that the second end of the transmission lever performs an adjusting movement for moving the decompression valve from the closed position into the open position.

摘要： A direct injection internal combustion engine, especially an Otto engine, is provided with layered lean operation and internal exhaust-gas recirculation. An exhaust-gas aftertreatment for reducing Nox using an Nox storage catalyst is also provided. This combination is to achieve the highest possible exhaust-gas recirculation rates with the lowest HC and Nox emission values. A tumble flow is provided for the incoming fresh gases, which may contain recirculated exhaust gas from external exhaust-gas recirculation. The swirl axis of the incoming fresh gases therefore extends substantially crosswise to the piston movement. This results in an emissions-reducing, optimal mixture inside the cylinder during the layered lean operation.

摘要： A method for controlling an internal combustion engine determines a desired torque based on an actuating position of an accelerator pedal. A normal fuel quantity based on a given normal efficiency is determined. A relative efficiency is determined based on at least current operating conditions of the internal combustion engine. The normal fuel quantity is corrected based on the relative efficiency in order to determine a fuel quantity which is to be metered to the internal combustion engine. A device for controlling an internal combustion engine is also provided.

摘要： A dust-collecting electrostatic precipitator has a housing, the top of which is adapted to form a pressure-relief opening and is closed by a sealing membrane divided by a plurality of intentional tear lines into zones which can be blown upwardly and back to relieve pressure within the housing. The membrane is covered, in turn, by a rain-shielding roof spaced above the sealing top and having a portion forming an elastic cover which is only loosely held against internal pressure.
