Abstract
A control linkage is provided between an actuating crank and the throttle butterfly valve of an internal combustion engine. The control linkage is a second degree hesitation mechanism, such as an epicyclic gear train, for example having a gear ratio of 4:1 and an eccentricity ratio of between 0.7 and 0.8. The control linkage results in a more linear relationship between engine output and the rotational movement of the actuating crank.
