摘要： A manually guided implement having an internal combustion engine, especially one embodied as a two-stroke engine, is provided, and also includes a crankcase and a carburetor. The implement has a fuel-conveying system for supplying fuel to the carburetor. Downstream of the carburetor, via a power line and a metering device disposed in the primer line, the fuel-conveying system is connected to an area that in the intake phase communicates with the crankcase. The metering device is controlled by the pressure in the crankcase.

摘要： An air filter for an internal combustion engine has a housing with an interior chamber. The housing has housing walls at least one of which is in the form of a filter element. One of the housing walls has a suction opening for connecting the air filter to a suction channel of the combustion engine, wherein combustion air flows through the filter element into the interior chamber and from the interior chamber through the suction opening into the combustion engine. Air flow resistance elements are arranged in the interior chamber upstream of the suction opening. The air flow resistance elements are arranged in a first and a second row. The first and second rows are spaced apart from one another in the direction of flow of the combustion air. The air flow resistance elements of the first row of the second row are spaced laterally from one another to form gaps therebetween. The air flow resistance elements of the first row are positioned so as to be substantially aligned with the gaps of the second row.

摘要： An ignition circuit is for an internal combustion engine in a handheld portable work apparatus. A combustion chamber (4) is configured in the cylinder (3) of the engine (1) which is delimited by a piston (5) driving a crankshaft (7). A pole wheel (10) revolves with the crankshaft (7) and is assigned to an induction loop (13). The pole wheel periodically changes the magnetic flux in the induction loop. An ignition capacitor (16) is charged by a charge coil (14) of the induction loop and is discharged via a discharge circuit (15) via an ignition coil (17). The ignition coil is connected to a spark plug (19) projecting into the combustion chamber. For achieving a powerful ignition spark, the discharge of the ignition capacitor is prevented by an rpm evaluation circuit (23) when the rpm curve (30) exhibits an rpm change (Δn) which exceeds a pregiven threshold value.

摘要： A device that controls the engine speed of an internal combustion engine of a hand-held power tool has a protective control unit. The engine has an ignition control unit for controlling the ignition timing relative to a crank angle of a crankshaft based on the crankshaft speed and also has a centrifugal clutch driven by the crankshaft that begins to engage when a first engine speed is surpassed and is fully engaged when a second engine speed is reached. The protective control unit is activated within an engine speed range between the first and second engine speeds and monitors a dwell time of the actual engine speed within the engine speed range. When a predetermined dwell time of the actual engine speed is surpassed, the protective control unit intervenes in the combustion process and corrects the engine speed to a value that is outside of the engine speed range.

摘要： An ignition circuit for a two-stroke engine has a spark plug connected via an ignition switch to a voltage source. The ignition switch is actuated via a control circuit to close the ignition switch in dependence upon the crankshaft angle and the rpm of the engine and to trigger an ignition spark per revolution of the crankshaft. For one and the same rpm, the control circuit makes available an ignition time point for the idle case and an ignition time point for the acceleration case. To achieve rapid acceleration from idle, the control circuit monitors idle rpm to switch to an ignition time point for the acceleration case for a pregiven rpm increase. If the control circuit determines an absence of the rpm increase or drop after ignition switchover to the acceleration case, then there is a switch back to the ignition time point for the idle case.

摘要： A centrifugal clutch is provided, especially for manually-guided, motor-driven implements such as chainsaws and the like. The clutch comprises centrifugal bodies, each of which is essentially comprised of a shoe that has the shape of a circular arc and has a support member. The shoes are held and guided by guides on a carrier member that is disposed on the drive side. On the output side, the clutch is essentially formed of a drum having a surface that axially and radially spans the centrifugal bodies. Disposed at each end of a centrifugal body is a projection and a complementary recess, which both extend approximately tangentially relative to the drum.

摘要： The invention relates to a two-cycle engine for a drive engine in a portable, manually operated tool. The combustion chamber formed in a cylinder is delimited by a piston that moves up and down, whereby the piston, by means of a connecting rod, drives a crankshaft rotatably mounted in a crankcase. The combustion chamber has an outlet for removing waste gases, and provided for supplying a fuel/air mixture prepared by a mixture preparation device, and combustion air, are gas-supplying channels that open into the combustion chamber. In order to reduce scavenging losses, it is provided that for the entire duration of the gas exchange exclusively air flows in the area near the outlet and exclusively fuel/air mixture flows out of the crankcase in the area further away from the outlet.
