摘要： A primary passage and a secondary passage in a parallel relation to each other are disposed between an air cleaner and a branch passage collecting portion of an intake manifold. The primary passage is smaller in diameter than the secondary passage and has at the downstream end thereof a laval nozzle through which air flows at the speed of sound even under low-speed low-load engine operating conditions. The laval nozzle is connected to a carburetion chamber which is elongated straightly in the direction downstream of the laval nozzle. A fuel injection valve is disposed in the primary passage at a place upstream of the laval nozzle. A pressure control valve is adapted so that a vacuum higher than a predetermined value is developed in the carburetion chamber at any time. A primary throttle valve and a secondary throttle valve are interconnected so that the secondary throttle valve is held closed unless the primary throttle valve is fully open. The primary throttle valve is movable in response to an engine operating condition.
摘要翻译：在空气滤清器和进气歧管的分支通道收集部分之间设置有彼此平行关系的主通道和次通道。主通道的直径比二次通道的直径小，并且在其下游端有一个拉链喷嘴，即使在低速低负载发动机运行条件下，空气以声速流过。喷泉喷嘴连接到在油槽喷嘴的下游方向上直线延伸的化油室。燃料喷射阀设置在主通道中，在喷嘴喷嘴的上游位置。压力控制阀适于在任何时候在化油室中产生高于预定值的真空。主节流阀和辅助节流阀相互连接，使得次级节流阀保持关闭，除非主节流阀完全打开。主节流阀可响应于发动机工作状态而运动。

摘要： Adjustment is made of the position of a marine transportation system including a boat having a drive, a trimmable port tab and a trimmable starboard tab. The operation of the marine transportation system is monitored to provide an output distinguishing boat operation in an on-plane condition and boat operation in an off-plane condition, to provide an output distinguishing boat travel in a straight forward condition and boat travel in a turning condition and to provide an output distinguishing boat operation in a first heel condition in which the boat tilts to port and boat operation in a second heel condition in which the boat tilts to starboard. The port and starboard tabs are positioned at desired positions in response to the outputs. According to the embodiment, a heel adjustment operation of the boat is carried out during boat operation in an on-plane straight forward travel condition, only.

摘要： In a variable venturi carburetor in which the metering jet portion of fuel changes automatically according to the amount of intake air required to keep the mixture at a constant air-to-fuel ratio at all times, two series-arranged nozzles and an auxiliary fuel passage communicating with the downstream side of the venturi and with the space formed between the two nozzles additionally formed at the fixed venturi portion in such a way that the auxiliary fuel passage can be opened or closed according to engine operating conditions. Therefore, when the auxiliary fuel passage is opened, since fuel is introduced into the venturi through only a single nozzle, a rich mixture is obtained; when the auxiliary fuel passage is closed, since fuel is introduced through two nozzles, a lean mixture is obtained.
