Title: Variable choke carburettor with idling system
Inventor: SEHRNDT CHRISTIAN DIPL ING
IPC: F02M9/00
Filed: 1982-03-29
Abstract: The invention relates to a system which ensures the idling of the internal combustion engine, in which the fuel feed is performed by means of a variable choke carburettor. The object of the invention is to improve the service characteristics, especially the fuel saving, the reduction of pollutant emissions and the handling in the transitional range by cost-effective means. The solution according to the invention is characterised in that an idling fuel duct, which connects the idling fuel nozzle to the main nozzle switch is so arranged that it opens out into its internal chamber far above the fuel level but below the metering cross-section of the nozzle needle. When the internal combustion engine is idling, the fuel level in the internal chamber of the main nozzle switch is thereby raised up to the idling fuel duct without the main carburettor system operating. When the throttle slide is opened the main mixture system can operate fully, even with the slightest vacuum in the carburettor venturi tube, since the fuel level is directly in front of the mixture outlet. <IMAGE>
