摘要： A variable stage type carburetor provided with a venturi vane which is adapted to vary the venturi area in a venturi portion thereof, commensurate to the opening of a throttle valve. This carburetor features that, in the running condition where the opening of a throttle valve is considerably large and yet the quantity of intake air is relatively less, the venturi vane is forcedly displaced in a direction to be closed so as to increase the venturi negative pressure in the venturi portion, thereby enhancing the injection of fuel.
摘要翻译：具有文丘里叶片的可变台型化油器，其适于改变文丘里部分的文氏管面积，与节流阀的开度相当。这种化油器的特征在于，在节流阀的开度相当大并且进气量相对较少的运行状态下，文丘里叶片被迫在关闭的方向上移位，以增加文丘里管的负压在文丘里部分，从而增强燃料的注入。

摘要： A secondary air control device which comprises an air passage communicating an air pump with a recombustion device and having a resistor such as an orifice provided midway of the passage and a control valve for maintaining substantially constant the pressure ratio of the pressure on the upstream side of the aforesaid resistor to that on the downstream side thereof, said control valve being so designed as to be operated in association with the pressure of the secondary air and that of exhaust gas, thereby eliminating fluctuation in pressure in the secondary air due to reduction in the discharging performance of the air pump, and thus the secondary air proportional in quantity to the exhaust gas from an engine may be supplied.

摘要： An intake system adapted to be used in combination with an internal combustion engine having a main combustion chamber and a preliminary or subcombustion chamber equipped with an ignition plug. There is provided an intake cylinder having a venturi portion which allows the passing of the total amount of air being fed to both combustion chambers and a throttle valve controlling the amount of air being fed to respective combustion chambers. The intake cylinder is divided into a main intake passage and sub-intake passage, both of which lead to both combustion chambers, respectively. A metering orifice is provided in the sub-intake passage, so that a ratio in amount, of air passing through respective intake passages may be maintained at a given value. In respective intake passages, there are provided fuel discharge values, to which are connected fuel passages leading from a single fuel pressure controlling valve for use in providing fuel pressure commensurate with the negative pressure in the venturi portion. By the provision of the metering orifices in respective fuel passages, a ratio in flow rate, of fuel being introduced to respective fuel discharge valves is maintained at a given value. Thus, there is provided an intake system in which a ratio in flow rate, of mixture charges being fed to the main combustion chamber and the sub-combustion chamber, as well as a ratio in air-fuel-ratio, of mixture charges being fed thereto are maintained constant.
