Carburator for internal combustion engines with electronic controlled organs capable of maintaining the idling speed of the engine at a constant level and controlling the position of the choke-valve during the warm-up phase.

摘要

Is described a carburator in which an electromechanical device operates on the throttle valve to define the little opening positions in function of the running conditions of the engine the electromechanical device is controlled by an electronic control unit which receives signals came from a sensor of the cooling water's temperature, from a sensor of the r.p.m. value and a sensor of the absolute pressure existing in the intake manifold. The electromechanical device possesses organs able to operate on the choke elastic means define a closing pressure working with a contour obtained on an extremity of a lever acted by an electromechanical device, to define the dinamic opening law of the choke, with the varation of the temperature and of the load applied to the engine.
