Abstract
After the engine is started and until its warming-up is completed, control of the degree of opening of an auxiliary carburetor for supplying an enriched fuel-air mixture to the engine is effected, independently of the degree of opening of the throttle valve of a main carburetor for supplying a dilute fuel-air mixture to the engine, by means of a diaphragm device which is adapted to produce a displacement in response to the pressure at the outlet of the main carburetor and a bimetal strip which is adapted to produce a displacement as the temperature of the engine gradually rises.
