    Abstract: PURPOSE: To provide the stability of rotation in extremely low speed by providing three intake ports in one cylinder, one of the ports being a port for supplying mixture within the full running range of an engine and the sectional area of an intake pipe to the intake port being smaller than that of a combined intake pipe path to the other intake ports.
    CONSTITUTION: Three intake ports 2 is provided in one cylinder. An intake pipe 5 communicating to one 2 of the intake ports is provided with a side valve system carbureter 9 driven by a wire 15 operated by a pivotable glip 14. The other two intake ports 2 are combined at the upstream side of a branch pipe 6a and have respectively throttle valves 11 which begin to open at a predetermined or more opening of a slide piston of the carbureter 9. A carbureter 10 having a constant vacuum system piston 10a is disposed upstream of the valve 11. The sectional area of te intake pipe 5 is smaller than that of the intake pipe 6, and intake flow speed is sufficiently high to provide stable combustion even in extremely low speed of an engine so that the stability of engine rotation is improved.

    【解決手段】 主シリンダー１の外側に拡張された燃焼室３の部分に、第二排気茸弁９が設置される。 バルブ・カバー７は、副シリンダー４内を往復運動し、第二排気茸弁９の底面を覆う。 ピストン２の上面に面して第一排気茸弁１０と吸気茸弁１１が設置される。 第二排気茸弁９が開弁して、高温で高圧の燃焼ガスが流失し始めた後に、第一排気茸弁１０が開く。 すると、第一排気茸弁１０の温度が低下し、ノッキングが発生し難くなり、圧縮比を増加できる。 すると、前記ピストンの仕事量が増加する。 この増加した仕事量が燃焼室内壁の表面積の増加による冷却損失量の増加を補償する。

    Abstract: PROBLEM TO BE SOLVED: To provide a means for compensating an increase in an amount of cooling loss due to increasing in a surface area of an inside wall of a combustion chamber expanded out of a cylinder.SOLUTION: A second exhaust poppet valve 9 is provided in a part of a combustion chamber 3 expanded out of a main cylinder 1. A valve cover 7 reciprocates within a sub-cylinder 4 and covers a bottom surface of the second exhaust poppet valve 9. A first exhaust valve 10 and an intake poppet valve 11 are provided to face an upper surface of a piston 2. After the second exhaust poppet valve 9 is opened and hot high-pressure burned gas starts to flow away, the first exhaust poppet valve 10 is opened. As a result, the temperature of the first exhaust poppet valve 10 is reduced to hardly cause knocking and the compression ratio can be increased. Then, a work amount of the piston is increased. Then, a work amount of the piston is increased. The increased work amount compensates an amount of cooling loss due to increasing in the surface area of the inside wall of the combustion chamber.

    Abstract: PURPOSE: To easily perform the subtle control of intake to two or more cylinders at the low revolution speed of an engine, by connecting an intake pipe to the upstream ends of slow revolution intake pipes for the cylinders, and providing a throttle valve in the former intake pipe.
    CONSTITUTION: When an internal-combustion engine is rapidly rotated, throttle valves 12 in rapid revolution intake pipes 5 and a throttle valve 13 in a slow revolution intake pipe 6 are greatly opened to supply a large amount of mixed gas into combustion chambers 2, 2' with high efficiency. When the engine is slowly rotated, the throttle valves 12 in the rapid revolution intake pipes 5 are entirely closed and the throttle valve 13 in the slow revolution intake pipe 9 is slightly opened so that a small amount of mixed gas produced by a single carburetor 8 is divided into two slow revolution intake pipes 6, 6 and then supplied into two cylinders 1, 1'.

    Abstract: One embodiment of the present invention relates to an engine intake port structure. According to the engine intake port structure of the embodiment of the present invention, a chamfer is formed to be eccentric to either side from an end corner of an intake port. Accordingly, the inflow of a fuel gas is concentrated on a side in which the opening width of the chamfer is wide in an initial opening stage during the opening and closing of the intake port by a valve unit, and after the opening of the intake port, the opening width is formed to be similar at four sides of the valve unit (160) such that swirls formed in the fuel gas are weakened. Thus, perfect combustion of the fuel can be anticipated by extending time during which the fuel gas remains in a combustion chamber.
