Abstract

PURPOSE: To promote the fuel atomization by equipping an auxiliary valve in the upstream of a throttle valve and keeping the auxiliary valve at the fixed initial opening thus increasing the air flow rate at the auxiliary valve. When the quantity of air flow is low in spite of the high opening of the throttle valve.
CONSTITUTION: To equip an auxiliary valve 20 and counterweight 21 at the place where the valve axis is apart from the cylinder axis 0-0 by X in the upstream of a throttle valve 3. The auxiliary valve 20 is opened at an arbitrary angle inadvance, thus increasing the flow rate of the air passing through the valve and at the time atomizing the fuel being introduced from the upstream by the use of the flow rate. When the air flow rate reaches the prescribed quantity, the differential pressure before and after the auxiliary valve exceeds the force which is to close the valve by the counterweight 21 and the valve opens further gradually. The valve opens fully when the high velocity high load range is attained. In this state, the fuel atomization is comparatively good. Since the differential pressure before and after the throttle valve is high and the flow rate at the auxiliary valve is high in a low velocity and low load range, the fuel atomization is promoted in the throttle valve area.
