    摘要: An exhaust gas recirculation system for an internal combustion engine includes an exhaust gas recirculation passage for communicating an exhaust port with an intake passage through a recirculation flow control valve. The recirculation system according to the invention comprises a timing valve in the recirculation passage adapted to open at specified moments for extracting exhaust gases containing highly concentrated hydrocarbons. According to the invention, moreover, the exhaust port is concentrically divided into a plurality of ports to extract exhaust gases having high concentrations of hydrocarbons from the outermost divided port adjacent to the inner peripheral walls of the exhaust port to recirculate them into intake mixtures, thereby reducing the concentrations of hydrocarbons and nitrogen oxides in exhaust gases and thus fuel consumption.

    摘要: The first of a pair scissor like rocker arms is pivotally mounted at one end either by way of an adjust screw or a hydraulic lash adjuster and arangement to engage the top of a valve stem at the other. A cam follower which is located between the first and second ends engages a lift cam. The second of the rocker arms is pivotally mounted on the first one and has a closure cam follower at one end and engages the lower face of a retainer which secured to the top of the valve stem by way of a ring type collet. The shaft on which the second rocker arm is pivotally mounted can be provided with eccentric portions which enable the second rocker arm valve clearances to be adjusted separately from the adjustment of the first rocker arm clearance. The arrangement can be adapted to lift and close two valves.

    摘要: A spark ignition fuel injection reciprocatory internal combustion engine with dual induction system is provided which has within a cylinder head a primary intake port passage to direct air charge into a cylinder to swirl therein and a secondary intake port passage to direct air charge into the cylinder in such a direction as to impede and reduce the swirling motion of the air charge issuing from the primary intake port passage. An intake valve, including a valve stem and a valve head, is reciprocably mounted within the cylinder head, and an annular wall or tube is fixedly positioned in a bore in the cylinder head. The primary intake port passage communicates with the exterior of this tube and the secondary intake port passage communicates with the interior of the tube. This tube extends to a position closely adjacent to, or in engagement with, the valve head of the intake valve when the valve is in the closed position. A fuel injector, mounted to the cylinder head, discharges fuel into the secondary intake port passage toward the central portion of the head and synchronization with the opening of the intake valve so that the fuel issuing from the fuel injector will impinge upon the valve head and then disperse radially outwardly toward the periphery of the valve head. An air flow sensor is provided upstream of primary and secondary throttle valves to detect the total of flow of induction air fed to the engine so that fuel is discharged at a rate proportional to the total induction air flow.
