<p>A device which can be fitted to controlled-ignition internal combustion engines, whether 2 or 4 stroke, or with a Wankel type rotary piston, or similar, comprises a piston valve (11) that works in association with a metering rod (12) to adjust the flow of petrol delivered to the Venturi of the carburettor; the metering rod (12) is made independent from the position of the piston valve (11) by the use of a linear actuator (13) with electric servo control, managed by a control unit or CPU, which activates the metering rod (12) making it carry out controlled axial movements.</p> |
