INTERNAL COMBUSTION ENGINE AND METHOD FOR SAFE STARTING THE SAME

An internal combustion engine for driving a working assembly with a clutch， including a combustion chamber into which a mixture of fuel and air is supplied， a spark plug to ignite the mixture， ignition of the mixture driving a piston operably coupled to a crank portion of the engine， a fuel supply system including a fuel valve and a throttle valve， a throttle position sensor configured to determine a position of the throttle valve， a speed sensor configured to determine engine speed， and an electronic control unit configured to control operation of the fuel valve and the spark plug， the electronic control unit being configured to initiate a speed limitation operation in response to a first position of the throttle valve at engine start-up， wherein the speed limitation operation continues until the throttle valve is moved from its first position.
