摘要： In order to insure that, even when there arises a change in the rate of air flowing through an intake mixture passageway, the air-fuel ratio of the mixture which is to be supplied to an engine is always kept constant, the fuel control system comprises: an intake mixture passageway having a first negative pressure generating section and a second negative pressure generating section provided upstream of the first negative pressure generating section for generating a negative pressure weaker than that in the first negative pressure generating section; a fuel passageway having its one end opening in the first negative pressure generating section and its other end connected to a float chamber via fuel metering jet; an electromagnetic valve for controlling the rate of the fuel flowing through the fuel passageway; a negative pressure passageway having its one end opening in the second negative pressure generating section and having its other end connected to the fuel passageway at a site located between the fuel metering jet and the electromagnetic valve; and a level detecting means for detecting whether or not the fuel column formed within the negative pressure passageway is at a preset level and capable of generating an electric signal to control the operation of the electromagnetic valve. The first and second negative pressure generating sections are each constructed by a fixed and/or a variable venturi.

摘要： Especially applicable to motorcycle engines, it consists of establishing in the main conduct through which the air from the filter (FA) arrives, whose flow is controlled by a butterfly valve of gases or main valve (1), a secondary butterfly valve (2) that keeps each operation in functioning, be it in stationary or transitory regime, the opening being appropriate for producing the loss of load that, added to the Venturi effect generated in the conduct section downstream from the aforementioned secondary butterfly valve (2) and the loss the load of the air filter (FA), giving rise to the appropriate suction at the emulsioned fuel outlet (3), the fuel from a cell (4) of constant level being mixed with the air flow, joined to the atmosphere, such that the suction at the outlet (3) produces a flow through and controlled by the main distributor (5), which emulsioned with the air from the tube (9), equipped with transverse holes, discharges in the central conduct of the system (11) through the outlet (3).
