摘要： An internal combustion engine having an intake channel that opens into a crankcase. A first fuel channel opens into the intake channel to supply fuel thereto as a function of underpressure in the intake channel. An auxiliary channel opens into a transfer channel that fluidically connects a crankcase to the combustion chamber. A second fuel channel opens into the auxiliary channel and is connected to a storage reservoir for fuel. At least one valve controls the quantity of fuel to be supplied to the engine via the auxiliary channel. Largely fuel-free air is supplied to the engine via the intake channel during idling. During a first revolution of the crankshaft, fuel is supplied via the auxiliary channel, so that a combustible mixture can form in the combustion chamber. During a second revolution, largely fuel-free air is supplied via the auxiliary channel and the combustion chamber is scavenged with largely fuel-free air.

摘要： The invention is directed to a method for operating a two-stroke engine having a cylinder in which a combustion chamber is formed and which includes devices for metering fuel and supplying combustion air as well as an ignition device for igniting a mixture in the combustion chamber. In the method, fuel and combustion air are supplied to the engine and the mixture in the combustion chamber is ignited. The combustion chamber is delimited by a piston which drives a crankshaft rotatably journalled in a crankcase. A control is provided which controls the metering of fuel and the ignition of the mixture in the combustion chamber. In the method, the two-stroke engine is controlled in at least one operating state so that the number of combustions is less than the number of revolutions of the crankshaft in the same time interval.

摘要： A carburetor arrangement is provided for an internal combustion engine that is to be started with a pull cord. A fuel channel that is connected with a fuel-filled storage space opens into and supplies fuel to an intake channel portion as a function of the underpressure in the intake channel portion. The underpressure in the intake channel portion is increased during the start-up process via a start-up mechanism. To keep the engine ready to run with the start-up mechanism engaged, a control valve is disposed between the storage space and where the fuel channel opens into the intake channel portion. The control valve is opened or closed by a control unit as a function of the speed of the internal combustion engine.

摘要： An ignition circuit for a two-stroke engine has a spark plug (2) which is connected via an ignition switch (14) to a voltage source (16). The ignition switch (14) is actuated via a control circuit (15) in order to close the ignition switch (14) in dependence upon the crankshaft angle and the rpm of the engine (1) and to trigger an ignition spark per revolution of the crankshaft (10). For one and the same rpm, the control circuit (15) makes available an ignition time point for the idle case and an ignition time point for the acceleration case. In order to achieve a rapid acceleration from the idle range, the control circuit (15) monitors the idle rpm in order to switch over 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 even an rpm drop after the ignition switchover to the acceleration case, then there is a switch back to the ignition time point for the idle case.

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.
