Abstract

PURPOSE: To avoid the excessive rise in the rotational frequency of a super-charger in a region of high speed and partial load and prevent fuel efficiency from falling due to the excessive rise in exhaust pressure, by changing the degree of opening of an exhaust release valve depending on the rotational frequency of an engine.
CONSTITUTION: In a controller 13 for an exhaust release valve 11, the rotational frequency of a rotary shaft 20 rises due to the increase in that of an engine so that the centrifugal force acting to centrifugal weights 21 increases and they spread. The spreading motion of the centrifugal weights 21 moves a spacer 22b in the direction of an arrow through rollers 22a to displace a shaft 23 leftward against the force of a spring 24 to open the exhaust release valve 11 through a linkage 12. When the rotational frequency of the engine has exceeded a level predetermined by the set force of the spring 24, the exhaust release valve 11 is opened so that the degree of opening of the valve 11 is heightened with the rise in the rotational frequency.
