摘要： Disclosed herein is an improvement in a variable venturi carburetor for an internal combustion engine which comprises a venturi portion, a float chamber, a main fuel passage communicating with the venturi portion and with the float chamber, a main jet provided in the main fuel passage and a movable metering needle of which free end is adapted to control the size of the main jet and the base portion thereof is mounted to a suction piston adapted to transversely move with respect to the venturi portion in response to the condition of load on the internal combustion engine. The improvement includes provision of a fuel bypass which detours the main jet for supplying part of fuel to the venturi portion. The fuel bypass communicates with the atmosphere through one or more throttles.

摘要： Disclosed are an exhaust gas cleaning apparatus of an internal combustion engine, which is provided with a three-way catalytic converter, and an air injection system responsive to the air-fuel ratio of the exhaust gas in the exhaust pipe for increasing or decreasing the amount of secondary air directed to the exhaust pipe so that the air-fuel ratio in the converter is maintained near the stoichiometric value. Means are provided for obtaining a high rate of increase in the introduction of secondary air when the acceleration pump is operated for introducing an amount of excess fuel into the engine during acceleration of the engine. Thus, the air fuel ratio occurring during this condition can be effectively controlled near the stoichiometric value.

摘要： The object of the present invention is to promote warming-up operation in a cooling water flow control system of an internal combustion engine. A flow control valve is provided at a junction of a radiator passage and a bypass passage. Radiator flow rate and bypass flow rate of the flow control vale are controlled by detecting engine outlet water temperature, radiator outlet water temperature, number of revolutions of engine, and suction pipe negative pressure. The cooling water in the bypass passage passes through a throttle body, and flow rate is controlled to a totally closed flow rate or a micro-flow rate in the warming-up operation, and this contributes to the promotion of the warming-up operation.

摘要： A device for controlling the operation of a carburetor comprising a wax valve fitted into a bore formed in the device housing. A wax valve holder is fitted into the bore so as to surround the temperature sensitive portion of the wax valve. A cooling water passage is formed in the bore so as to surround the wax valve holder. A heat insulating space is formed between the outer wall of the temperature sensitive portion and the inner wall of the wax valve holder.
