  • Control Of Throttle Valves Provided In The Intake System Or In The Exhaust System (AREA)

Abstract

PURPOSE: To operate an exhaust emission control or a fuel saving control from a negative pressure, by providing a Venturi portion in the upstream of one throttle valve and detecting the negative pressure, in the air valve, where two throttle valves are provided in parallel in the intake passage and made interlocking motion of valve opening.
CONSTITUTION: In the intake passage of an air valve 1, are provided two passages 2, 3. With a lever 8 rotated, a throttle valve 4 is opened to flow air. With the lever 8 further rotated, the point end of a connecting rod 10 is contacted to the end part of a groove 9, and a lever 11 is also rotated. Accordingly, another throttle valve 5 is also opened, and air quantity can be increased to a maximum amount. In the upstream of the throttle valve 4, is constructed a Venturi portion 15, and a negative pressure is generated by opening the throttle valve 4. This negative pressure is used as the negative pressure source for control of EGR valve of an exhaust emission control measure of for acceleration sensor and the like.
