摘要： A method for controlling an ignition system of an internal combustion engine having a primary firing pulse generator for charging a capacitor. An electronic switch is included for discharging the capacitor via an ignition coil to generate an ignition voltage. A microcomputer operates the switch to control the ignition timing of the generator. The microcomputer is in communication with a speed sensor that detects the rotational speed of the engine and a speed limitation control that limits the engine speed to a limitation speed below the clutch-in speed of an included centrifugal clutch. The speed limitation control is active or activated when one of either starting the engine or an operating problem of the power tool is detected. The speed limitation control is deactivated when a low speed state of the engine is detected.

摘要： A diaphragm carburetor having a carburetor casing defining a mixing passage. A measuring chamber is disposed in the carburetor casing and is partitioned into a fuel chamber and a compensation chamber separated by a control diaphragm. The compensating chamber is closed to the surrounding atmosphere but is connected to a channel. An opening of the channel enters into a space between the air filter and a fuel inlet in the mixing passage. The channel is at least partially defined by a pipe extending through the carburetor casing. The pipe is adapted for assembly/disassembly from outside of the casing. The pipe is attached to a spacer for properly orienting and fixing the pipe relative to the casing during assembly.

摘要： The invention concerns a method for controlling the fuel supply to an internal combustion engine at start-up, the engine having a fuel supply system. The invention also concerns a carburetor having a fuel supply system including a main fuel path connecting a diaphragm controlled regulating chamber to a main outlet in the region of the venturi section, the main fuel path including an actively controlled fuel valve, and an idling fuel path branching off from the main fuel path downstream of the valve and ending in at least one idling outlet in the region of a throttle valve, the fuel supply system further including a start fuel line starting upstream or downstream of the fuel valve and ending in at least one start fuel outlet to the intake channel.
