Abstract

Automatic control and fuel saving means for internal combustion engines, comprising: at least one centrifugal speed sensor having at least one pair of flyweights, which flyweights are disposed in the guide tracks on a holder, the said guide tracks are such orientated that the components of the centrifugal forces of the flyweights in the guide track directions substantially match the elastic forces of the spring exerting on the flyweights; a mode shifting device connected to the said speed sensor and to the manual operating mechanisms, the said mode shifting device alternately puts the engine into the automatic control mode by the said speed sensor or into the manual control mode.
