Abstract

An automatically controlled choke valve (3) is located upstream of a main fuel supply system and a butterfly valve (2) and a passage for delivering an additional air/fuel mixture is provided with a solenoid closure valve (107). That solenoid valve is controlled by an electronic circuit (111) arranged to deliver periodic electrical signals whose duty ratio depends on the temperature of the engine as detected by a sensor (112).
