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： 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： 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： 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： 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.

摘要： An exhaust gas recirculation apparatus for an internal combustion engine, which has a so-called EGR (Exhaust Gas Recirculation) valve provided with a vacuum actuator for controlling the amount of exhaust gas to be recirculated. An air introducing pipe is opened to the intake system for introducing an extra amount of air into the engine. An air control valve is provided on the air introducing pipe for stopping this introduction of the extra amount of air into the engine so that a rich air-fuel mixture can be supplied into the engine when the engine is beginning to accelerate from a low rotational speed. The vacuum actuator of the EGR valve is connected to this air introducing pipe, in order to carry out an EGR operation when a rich combustible mixture is supplied to the engine.

摘要： In a process of mounting a camshaft 20 to a supporting member 10, a shaft body 21 is firstly inserted into a first bearing hole 13F in the front side of the supporting member 10, before the shaft body 21 is axially moved toward the second bearing hole 13R. In order to get a cam lobe 22 through a concave bearing portion 13M in a semicircular arc shape, rotation of the camshaft 20 enables a cam nose 22b to be directed downward, which is opposite from the concave bearing portion 13M. This enables avoiding the interference between the cam nose 22b and the concave bearing portion 13M, even when the curvature radius of the concave bearing portion 13M is reduced. Consequently, reduction of the curvature radius of the concave bearing portion 13M achieves the downsizing of the supporting member 10.
摘要翻译： 在将凸轮轴20安装在支撑部件10上的过程中，在轴体21朝向第二轴承孔轴向移动之前，首先将轴体21插入支撑部件10的前侧的第一轴承孔13F 13R。 为了通过半圆弧形状的凹入轴承部分13M获得凸轮凸角22，凸轮轴20的旋转使得凸轮端头22b能够向下指向与凹入轴承部分13M相反的向下。 这样，即使凹入轴承部13M的曲率半径减小，也能够避免凸轮凸起22b与凹入轴承部13M之间的干涉。 因此，凹入轴承部13M的曲率半径的减小实现了支撑部件10的小型化。
