Carburetor for a Combustion Engine, and Method for the Controlled Delivery of Fuel

摘要

In order to allow fuel to be delivered in a controlled manner into a mixing chamber of a carburetor, a needle is displaced towards a needle seat between an open and a closed position in a clocked manner relative to an intake stroke of the engine such that the amount of fuel that flows into the mixing chamber via a fuel duct is controlled in accordance with the rotational speed and the engine load.
