摘要： A fuel control system for use in an internal combustion engine wherein the combustion device thereof comprises a main combustion chamber and an auxiliary combustion chamber provided therein with an ignition plug, the main and auxiliary combustion chambers communicating with each other through a through-hole. A rich mixture of gasified fuel and air is supplied to the auxiliary combustion chamber and a lean mixture of gasified fuel and air is supplied into the main combustion chamber and the mixture in the main combustion chamber is ignited by the flames produced in the auxiliary combustion chamber. A main air intake passageway and an auxiliary air intake passageway are provided and communicated respectively with the main combustion chamber and the auxiliary combustion chamber, and a fuel control system capable of varying the pressure for fuel supply in accordance with the negative pressure of a Venturi flume provided in the main air intake passageway and a fuel passageway for supplying the fuel controlled by said fuel control system to the main and auxiliary air intake passageways respectively at a predetermined distribution ratio, thereby making it possible to produce predetermined volumes of mixtures of gasified fuel and air respectively in the main and auxiliary air intake passageways.

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.
摘要翻译：一种二次空气控制装置，其特征在于，包括：空气通路，其与空气泵连通，所述空气通路具有与所述通气装置连通的空气泵，并且具有诸如设置在通道中途的孔口的电阻;以及控制阀，用于将所述压力上游侧的压力上述电阻器与其下游侧的电阻器相对应，所述控制阀被设计成与二次空气和废气的压力相关联地操作，从而消除由于二次空气的减少引起的二次空气中的压力波动可以提供空气泵的排放性能，并且因此可以提供与来自发动机的排气成正比的二次空气。
