Abstract: The object of the present invention is to easily provide an appropriate amount of starting fuel for all-purpose engines, without requiring any special skill. The upstream side and downstream side of a throttle valve in an air intake passage are connected by a bypass. This bypass and a constant-fuel chamber are connected by an increased-fuel passage which is equipped with a check valve. The system is arranged so that the bypass and increased-fuel passage are opened and closed more or less simultaneously by an opening-and-closing valve. The necessary amount of starting fuel can be supplied to the engine in a short time by means of the increased-fuel passage, so that starting can be accomplished by cranking the engine a few times. The flow of air into the constant-fuel chamber from the bypass is prevented by the check valve so that rough idling and the need to expel inflowing air are eliminated; and starting operations may be performed in any desired order.

Abstract: An automatic cold start fuel supply device for use with constant depression carburetters having a damped air valve, comprises a fuel metering needle movable with engine temperature by a bimetallic element which acts on it indirectly via a rotary member. A spring, which is normally compressed by the action of manifold depression on a diaphragm, is adapted to act when expanded, through the diaphragm and a lever on an arm of the rotary member. The geometry of the lever and the rotary member is such that the rotary member is so positioned by the bimetallic element when the engine is warm that it is not rotated by the load that is applied to its arm by the action of the spring whereas it is so rotated against the action of the bimetallic element when the engine temperature is below the normal running temperature.

Abstract: An auto-enrichener for an engine, including an enriching conduit for carrying fuel and air to an engine, and a valve disposed in the conduit. The valve is adjustable between at least an open configuration and a closed configuration. In the open configuration passage of fuel and air through the conduit is enabled, and in the closed configuration passage of fuel and air through the conduit is not enabled. The auto-enrichener also includes a thermal expansion element in communication with the valve. The thermal expansion element expands with increasing temperature and contracts with decreasing temperature to activate the valve. The auto-enrichener also includes a heater that hears the thermal expansion element when the engine is operated.

Abstract: A carburetor for an internal combustion engine including a main suction conduit having a control throttle and a starting suction conduit having an on-off valve and opening at one end in a portion of the main suction conduit disposed downstream of the control throttle, wherein a main fuel passage and a main air bleed passage having a main air bleed for the main fuel passage are provided for the main suction conduit. A communication passage is provided to communicate a portion of the starting suction conduit disposed upstream of the on-off valve with a portion of the main air bleed passage disposed upstream of the main air bleed. By this arrangement, when the throttle valve is opened to accelerate the engine before it is completely warmed up after being started, the suction pressure from the starting suction conduit is transmitted through the communication passage to the upstream side of the main air bleed passage whereby the fuel-air mixture supplied through the main suction conduit to the engine can be enriched substantially at a uniform rate.

Abstract: A carburetor for an internal combustion engine has an auxiliary starting device for delivering fuel and air to the induction passage during starting and cold running. The starting device comprises a duct opening into the induction passage downstream of the throttle means receiving fuel and air, and provided with a closure valve opened until the temperature of the engine has reached a first predetermined value. The flow of fuel entering the duct is reduced upon the engine becoming self operative. A flap located in the induction passage upstream of the opening of the main fuel delivery system is biased toward opening by the air flow around it and is resiliently biased toward closure with a force which decreases as the temperature of the engine increases.
