摘要： A variable venturi-type carburetor comprising a metering jet and at least one air-bleed bore formed on the cylindrical inner wall of the metering jet. The amount of air fed into the fuel passage of the carburetor from the air-bleed bore is controlled by an output signal from the oxygen concentration detector arranged in the exhaust manifold so that the air-fuel ratio of the mixture fed into the cylinder of the engine becomes equal to the stoichiometric air-fuel ratio. The metering needle is arranged so that it contacts the cylindrical inner wall of the metering jet and partially covers the air-bleed bore.

摘要： A fuel evaporation control, or vapor recovery system including: a charcoal canister housing therein activated charcoal adapted to adsorb gasoline vapor from a fuel tank; a purge port leading to a canister and opening into an intake passage in such a position that a throttle valve for the carburetor may assume an upstream position and a downstream position relative to the purge port, depending on its open positions; and a valve for controlling communication between the charcoal canister and a portion of the intake manifold, which is downstream from the throttle valve, in response to the operational condition of the engine. This fuel evaporation control system allows the vapor from the fuel tank to pass into the engine during engine deceleration or when the engine is loaded over a given load level. This system, however, interrupts the supply of gasoline vapor to the engine, during engine idling or when the engine is lightly loaded. Because of the supply of gasoline vapor during engine deceleration, the charcoal canister may provide capacity enough to retain the gasoline vapor when the engine is loaded over a given load level so that the size of the canister need not be increased and the cleaning time of gasoline vapor with air through the canister may be shortened.
摘要翻译：一种燃料蒸发控制或蒸汽回收系统，包括：其中容纳有活性炭的木炭罐，其适于吸附来自燃料箱的汽油蒸气; 吹扫口，其通向罐并且进入进气通道，使得化油器的节流阀根据其打开位置可相对于吹扫口呈现上游位置和下游位置; 以及阀，用于响应于发动机的操作状况，控制活塞罐与节流阀下游的进气歧管的一部分之间的连通。该燃料蒸发控制系统允许来自燃料箱的蒸汽在发动机减速期间或当发动机在给定的负载水平下被装载时进入发动机。然而，该系统在发动机怠速期间或发动机轻载时中断向发动机供应汽油蒸气。由于在发动机减速期间供应汽油蒸汽，所以在发动机在给定的负荷水平下装载时，炭罐可以提供足够的能力来保持汽油蒸汽，使得罐的尺寸不需要增加，并且汽油的清洁时间可以缩短通过罐的空气蒸汽。

摘要： A helically-shaped intake port comprising a helical portion formed around an intake valve, and a substantially straight inlet passage portion tangentially connected to the helical portion. A bypass passage is branched off from the inlet passage portion and connected to the helical portion. A rotary valve is arranged in the bypass passage and actuated by a vacuum operated diaphragm apparatus. The rotary valve is opened when the amount of air fed into the cylinder of an engine is increased beyond a predetermined value.

摘要： A variable venturi-type carburetor comprising a main fuel passage which is open to the intake passage of the carburetor. An air bleed passage is connected to the main fuel passage. The inlet of the air bleed passage is divided into a first passage and a second passage. A first control valve and a first jet are arranged in the first passage. A second control valve and a second jet are arranged in the second passage. The second jet has a flow area which is larger than that of the first jet. The first control valve opens the first passage only when the engine is operating under an idling state. The second control valve opens the second passage only during the cruising operation of a vehicle.

摘要： Disclosed is an internal combustion engine provided with a charcoal canister for absorbing evaporative fuel issued from the fuel tank and/or the float chamber of the engine. A pipe is provided between the canister and the intake manifold which is always located downstream of the throttle valve of the engine, for desorbing the absorbed evaporative fuel by the flow of purge air which flow is formed in the canister under the influence of a vacuum existing in the intake manifold. Thus, the evaporative fuel can still be introduced into the engine even if the throttle valve is in its idle position.

摘要： In a variable venturi type carburetor having a slow speed system, a fuel vapor conduit is provided, an inlet of which is open to a main fuel passage, an outlet of which is open to an intake passage. Fuel vapor occurring in the main fuel passage is carried through the fuel vapor conduit, so as not to be introduced into a slow fuel passage; thereby, the engine is rotated stably with a relatively lean air-fuel ratio.

摘要： A control device comprising a push rod and a wax valve actuating the push rod in response to the temperature of the cooling water of an engine. The push rod is connected to the throttle valve of the carburetor so that the degree of opening of the throttle valve becomes smaller as the temperature of the cooling water of the engine is increased. The amount of air fed into the fuel passage from the air bleed passage is controlled by the push rod so that the amount of the air is increased as the temperature of the cooling water of the engine is increased. A vacuum-operated, time-delay valve is connected between the air-bleed passage and the atmosphere and increases the amount of air fed into the fuel passage from the air-bleed passage following a brief time delay period after the engine starts.

摘要： A variable venturi-type carburetor comprising a vacuum chamber, connected to a venturi portion of the carburetor, and a suction piston actuated in response to a change in vacuum in the vacuum chamber. A fuel passage is formed in the carburetor and is open to the intake passage of the carburetor. The suction piston has a needle extending through the fuel passage. An air bleed passage is connected to the fuel passage. When the level of vacuum in the intake passage becomes smaller than a predetermined level, the amount of air fed into the fuel passage from the air bleed passage is reduced, and the vacuum chamber is caused to be open to the atmosphere.

摘要： An internal combustion engine having a helically-shaped intake port. When the intake manifold vacuum is in the range of about -500 through -250 mmHg, a super lean mixture is fed into the cylinders of the engine. When the intake manifold vacuum is in the range of about -250 through -100 mmHg, a fuel mixture, having the stoichiometric air-fuel ratio, is fed into the cylinders of the engine. When the intake manifold vacuum is smaller than about -100 mmHg, a rich mixture is fed into the cylinders of the engine.
