摘要： A cylinder head gasket arranged between a cylinder head and a cylinder block in an internal combustion engine. The cylinder head gasket has a core web of steel with hooks arranged between facing sides of a pair of gasket plates made of a heat resistant resilient material, such as asbestos or graphite. Grommet rings are fitted to edges of openings in the web and the gasket plates aligned corresponding to the respective cylinder bores. The web has regions adjacent to the inner periphery of the aligned openings and located substantially inside of the grommet member rings, the regions containing no hooks, or containing hooks having a reduced height.

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： An apparatus for controlling valve timing in an internal-combustion engine. The apparatus includes a pair of sleeves inserted into each other. One of the sleeves is connected to the camshaft and the other sleeve is connected to a timing pulley which is connected to the crankshaft. One of the sleeves has diametrically opposed slits and the other sleeve has diametrically opposed slits located adjacent to the corresponding slits in the first sleeve. Abutment rollers are arranged in the slits and are mounted on an axially slidable slider. Movement of the slider causes the generation of an angular displacement between the sleeves, resulting in variable valve timing. A bearing unit is arranged between the inner and the outer sleeves.

摘要： A variable venturi-type carburetor comprising a suction piston which has a tip face defining a venturi portion. The tip face has a flat upstream end portion. A raised wall is formed on the inner wall of an intake passage, which faces the tip face of the suction piston. The raised wall has a tip edge having an approximately V-shaped cross-section. The flat upstream end portion of the tip face of the suction piston cooperates with the tip edge of the raised wall for defining an approximately isosceles triangular-shaped air inlet control opening therebetween when the amount of air fed into the cylinder of an engine is small.

摘要： A variable venturi carburetor wherein the suction piston is fully closed with respect to the venturi section at engine stop to elevate the negative pressure at the time of cranking, and is opened to a predetermined degree at the time of idling, thereby obtaining stable driving performance at a suitable air-fuel ratio. The suction piston slides, via a spring, into and out from a suction chamber communicating with a mixing chamber via a negative pressure path and has at its head a metering needle to face a metering jet. The low negative pressure occurring in the mixing chamber along with cranking is reliably applied to the gap between the metering needle and the metering jet which is wider than the gap in their matching state at the time of idling. Hence, the engine starts operating with an over-rich air-fuel ratio. The suction piston is shaped in such manner so as to close a venturi section on the upstream side with respect to the base portion of the metering needle at the time of stop of the engine. A venturi-crossing flange is disposed at a location corresponding to the position in the venturi section of either one or both of the suction piston head and a barrel member of the above-mentioned venturi section. Alternatively, an atmospheric pressure is communicated with the negative pressure to the suction chamber in order to enable driving at a set air-fuel ratio with a suitable lift movement.

摘要： A variable venturi type carburetor having a suction chamber disposed upstream from the throttle valve, a suction piston having an increased diameter portion in sliding contact with the suction chamber and movable back and forth in the suction chamber, a piston rod of the suction piston being in sliding contact with a guide rod of the suction chamber, and a compression spring interposed between the suction chamber and the suction piston. In this carburetor, the space between the guide rod and the piston rod is filled with air rather than damper oil. Additionally, the outer peripheral surface of a flange formed at the end of the guide rod and the inner peripheral surface of the suction piston cooperate with each other in defining therebetween a pressure transmission delaying clearance means through which a gas damper chamber defined in the suction piston is communicated with a vacuum chamber defined in the suction chamber at the opposite side of the flange to the damper chamber.
