摘要： An internal combustion engine has a cylinder with a combustion chamber delimited by a reciprocating piston that drives a crankshaft rotatably supported in a crankcase. The internal combustion engine has an intake passage, an exhaust connected to the combustion chamber, a device supplying fuel, and a control device controlling at least one operating parameter of the internal combustion engine. The internal combustion engine is operated in that a pressure is measured in operation of the internal combustion engine, an adjustable value for at least one operating parameter of the internal combustion engine is deteremined based on the measured pressure, and the determined adjustable value is set for optimized running of the engine.

摘要： An ignition device for a motor unit with an internal combustion engine provided with a piston, a combustion chamber with a spark plug, a crankshaft driven by the piston, an intake port supplying combustion air to the combustion chamber, an exhaust for removing combustion gases from the combustion chamber, a signal generator driven by the crankshaft and emitting for one crankshaft revolution an alternating voltage signal, has an ignition unit that triggers a spark at the spark plug at a preselectable timing. The ignition unit is a module separate from the motor unit. An alternating voltage signal generated by the signal generator is supplied to the ignition unit as an information signal sufficient for operating the internal combustion engine. The alternating voltage signal is supplied to a first unit for energy processing and to a second unit for processing information for control of the internal combustion engine.

摘要： A device for supplying water to a cutting wheel of a hand-held cut-off machine has a water-conducting line and a valve arrangement arranged in the line. The valve arrangement has a shut-off valve for controlling the water flow flowing through the line. The shut-off valve is actuated as a function of an operating signal of the cut-off machine such that in operation of the cut-off machine the water flow through the line is released by the shut-off valve. The shut-off valve interrupts the water flow through the line when the operating signal is absent.

摘要： A manually guided apparatus for collecting objects, especially fruits and nuts, including a pick-up drum rotatably mounted in the drum chamber of a housing. The drum is disposed approximately transverse to the direction of operation, and is rotationally driven by a drive unit. The housing has a wall section extending over the width of the drum approximately at the level of the outer diameter thereof. A ground support is disposed in the region of ends of the drum. A collection channel provides communication for picked-up objects between the drum chamber and a collection receptacle for receiving the objects. The wall section of the housing and the drum cooperate with one another such that objects are accelerated along the wall section toward the collection channel and are ejected out of the drum chamber along a trajectory into the collection receptacle. A handle is operatively connected to the housing for moving the housing in the direction of operation.

摘要： A method for operating an internal combustion engine having a fuel system which feeds fuel at a given pressure to a metering valve provides that a controller defines the opening time and the closing time of the metering valve and correspondingly actuates the metering valve so that the metering valve opens and closes at the defined times. In order to permit precise metering of fuel even in high-speed internal combustion engines there is provision for the controller to define at least one of the times for the opening or closing of the metering valve while taking into account the counterpressure actually prevailing at the outlet opening of the metering valve.

摘要： The absolute crankshaft angle of an internal combustion engine of a hand-held power tool is to be determined. The engine has a cylinder with a combustion chamber delimited by a piston that drives a crankshaft in a crankcase. The crankcase is connected by a transfer passage to the combustion chamber and the transfer port of the transfer passage is piston-controlled. Ignition takes place at an adjusted crankshaft angle. The energy supply unit of the engine is driven by the crankshaft and provides electric energy for ignition. The crankshaft angle is determined in that a signal generator is provided as an energy supply unit and generates an alternating voltage signal caused by a crankshaft revolution. An operating pressure signal of the engine is detected by a pressure sensor. The output signals of the pressure sensor and of the signal generator are linked with one another for determining the absolute crankshaft angle.
