Method of injection of fuel on the motor has two stages and a device for the embodiment of this

摘要

The invention relates to a method for the injection of fuel on the motor has two stages, provided for the tools, a manual control, in particular, such as chain saws or other. The injection pump 10 is powered by the pressure which reign in the casing 7, thus delivering the fuel required for the injection and the combustion in the engine 2. The fraction of the injection phase and the start of injection into the combustion chamber 5 is produced for a rise in pressure in the engine casing -. pressure, transferee of this latter in the injection pump, may be settled automatically as a function of the speed of rotation and or of the engine load conditions.
