Carburettor arrangement for internal combustion engine with magnet ignition system - involves electrical component directly or indirectly controlling fuel flow through carburettor mouthpiece

摘要

The magnet ignition system (1,2,3) is arranged to generator current to an electrical component (4) for control of fuel flow through the carburettor fuel mouthpiece. The electrical component consists of a heat unit, such as an electrical spiral (4), built into an airtight closed bellows which is coupled to an adjustment needle to the fuel mouthpiece. By heating the air in the bellows the latter extends and in turn activates the adjustment needle to alter the fuel flow through the mouthpiece. The bellows serves as thermic insulation against the carburettor body. The bellows varies its size with the alteration of the atmospheric air pressure and/or temp. and/or humidity, thus ensuring that the adjustment needle mechanical basic position is correct at each atmospheric condition.
