Abstract
A control device comprising a push rod and a wax valve actuating the push rod in response to the temperature of the cooling water of an engine. The push rod is connected to the throttle valve of the carburetor so that the degree of opening of the throttle valve becomes smaller as the temperature of the cooling water of the engine is increased. The amount of air fed into the fuel passage from the air bleed passage is controlled by the push rod so that the amount of the air is increased as the temperature of the cooling water of the engine is increased. A vacuum-operated, time-delay valve is connected between the air-bleed passage and the atmosphere and increases the amount of air fed into the fuel passage from the air-bleed passage following a brief time delay period after the engine starts.
