摘要： A carburetor for a multi-cylinder internal combustion engine which has for each cylinder a main combustion chamber defined above the piston in the cylinder and a sub-combustion chamber defined above the main combustion chamber and communicating with the latter through a torch nozzle. The carburetor has a main intake passage and a sub-intake passage for supplying a comparatively lean mixture and a comparatively rich mixture to the main and sub-combustion chambers respectively. The carburetor has a single throttle valve shaft extending across the main and sub-intake passages with a main throttle valve and a sub-throttle valve mounted on the valve shaft and disposed in the main and sub-intake passages respectively.The main and sub-throttle valves are attached to the single throttle valve shaft at the same attaching angle and have respective parallel surfaces and outer peripheral edge surface. The angle formed between the outer peripheral edge surface and the parallel surfaces of the main throttle valve and the angle formed between the outer peripheral edge surface and the parallel surfaces of the sub-throttle valve are different from one another so that the ratio of the open areas of the main and sub-intake passages is not constant as the throttle shaft is operated. Thereby, the ratio of weight of air introduced into the sub-combustion chamber to the weight of air introduced into the main combustion chamber can be controlled in accordance with the load condition of the engine.
摘要翻译：一种用于多缸内燃机的化油器，其对于每个气缸具有限定在气缸中的活塞上方的主燃烧室和限定在主燃烧室上方的副燃烧室，并且通过割炬喷嘴与其连通。化油器具有主进气通道和副进气通道，用于分别向主燃烧室和副燃烧室供应比较稀的混合物和较浓的混合物。化油器具有单个节流阀轴，其横跨主进气通道和副进气通道延伸，主节流阀和安装在阀轴上的副节流阀分别设置在主进气通道和副进气通道中。主节流阀和副节流阀以相同的安装角度连接到单个节流阀轴，并具有相应的平行表面和外周边缘表面。主外节边缘面与主节流阀的平行面之间形成的角度与副节流阀的外周缘面与平行面之间形成的角度彼此不同，因此开度主节气门和副进气通道的区域在节流轴工作时不是恒定的。由此，能够根据发动机的负载条件来控制引入副燃烧室的空气的重量与引入主燃烧室的空气重量的比例。

摘要： A method and apparatus for compensating for increased engine idle speed upon breaking-in of an engine, comprising halting a throttle valve controlling admission of air-fuel mixture to the engine in an idling position of the engine by a stopper member and gradually and automatically shifting the halted idling position of the throttle valve in its closing direction to diminish the flow of air-fuel mixture to the engine to compensate for increased engine idle speed upon breaking-in of the engine. The gradual and automatic shifting of the idling position of the throttle valve is obtained by constructing either the throttle valve, or the stopper member or both with contact portions which are relatively easily worn or deformed so that as the portions undergo gradual wear or deformation, the throttle valve gradually moves in its closing direction to compensate for increase engine idle speed.

摘要： A hollow space of limited volume is defined in the central aperture formed through a heat-conducting plate, held in contact with a planar temperature-responsive resistance element, to receive the bimetal and heater supporting shaft. By varying the diameter and/or the length of the space, the rates of heat transmission from the heater to the bimetal and the resistance element can be properly correlated with each other so that any premature current control or overheating is effectively prevented.

摘要： A dual carburetor system employs a main carburetor to supply a lean mixture to the main combustion chambers of an engine and an auxiliary carburetor to supply a rich mixture to the auxiliary combustion chambers of the engine. Each carburetor has a choke valve operated by a thermo-responsive device. Each carburetor has a locking lever which cooperates with an element connected to its choke valve to lock the choke valve in open position. A device responsive to temperature of the engine coolant operates a single member which moves both locking levers to locking position upon increase in temperature of the engine coolant.

摘要： A first choke valve is mounted in a main intake passage carrying a lean mixture to a main combustion chamber, and a second choke valve is mounted in an auxiliary intake passage carrying a rich mixture to a relatively small auxiliary chamber. Spark ignition of the mixture in the auxiliary combustion chamber projects a flame through a torch nozzle connecting the chambers to ignite the lean mixture in the main combustion chamber. Control of the main choke valve for moderately cold starting or extremely cold starting is accomplished automatically by means of a control element driven by a heat responsive bimetal element, or by means of a manually operated control element. In either case, overtravel of the control element after the main choke valve closes stores energy in a spring to increase closing torque of the main choke valve, and also moves the auxiliary choke valve toward closed position, to improve engine startability under extremely cold conditions. Both choke valves open in response to complete firing of the engine.

摘要： An automatic choke valve apparatus for an internal combustion engine in which an operation shaft connected to a choke valve provided in an intake passage of an internal combustion engine and a driving shaft connected to a pulse motor are connected together through an intermediate torsion spring and are engaged with one another through circumferentially disposed front and rear pawls for being feed-driven only in regular direction of rotation of the driving shaft. The choke valve is given a starting position setting in such manner that, by the operation of the pulse motor, the driving shaft undergoes excessive rotation beyond the fully closed position of the choke valve. A fast-idle cam cooperating with a throttle valve provided in the intake passage is angularly extended in one direction so as to form a low temperature cam portion comparatively large in cam height and the fast idle cam is connected to the driving shaft through a gang mechanism such as a link, so that in the course of excessive rotation of the driving shaft, the cam undergoes excessive rotation corresponding thereto and the low temperature cam portion is placed into operating position.
