Abstract
A method and apparatus for the limitation of the action of a manual choke by the recirculation of exhaust gases to the intake manifold is disclosed. A vacuum valve is located in a conduit connecting the intake and exhaust manifolds. The vacuum valve is activated by a vacuum transmitted through a conduit connected with the carburetor. The conduit is selectively opened by an electrovalve. The electrovalve receives a signal to open the conduit when the manual choke is activated and an engine temperature sensor indicates that the engine temperature has exceeded a predetermined value. A time delay circuit may delay the sending of the signal to the electrovalve.
