    摘要： When an engine is operated at a low and medium speed range, since the combustion pressure introduced into a pressure chamber of a valve drive unit is relatively small, a control valve is projected toward the cylinder by the biasing force of a spring so as to lower the upper edge of the exhaust port. At the same time, in conjunction with this motion of the control valve, a resonance chamber is opened so as to communicate between the resonance chamber and the exhaust port, thereby the engine power is increased. When the engine is operated at a high speed range, since the combustion pressure is relatively large, the control valve goes away from the cylinder so as to enlarge the exhaust port and at the same time, in conjunction with this motion of the control valve, the resonance chamber is closed, thereby the engine power is increased.

    摘要翻译： 当发动机在低速和中速范围下运行时，由于引入阀驱动单元的压力室的燃烧压力相对较小，所以通过弹簧的作用力使控制阀向气缸突出，从而降低 排气口的上边缘。 同时，结合控制阀的这种动作，共振室被打开，以便在共鸣室和排气口之间连通，从而增加发动机功率。 当发动机在高速范围下工作时，由于燃烧压力相对较大，所以控制阀离开气缸，从而扩大排气口，同时结合控制阀的运动， 共振室关闭，从而发动机功率增加。

    摘要： An internal combustion engine comprises a cylinder, a piston reciprocating in the cylinder, piston rings arranged on the periphery of the piston, and at least a pair of oil ports symmetrically provided in a wall member of the cylinder. The oil ports communicate with the space between the wall member and the piston and are positioned to open onto the portion below the lowermost piston ring during the reciprocation of the piston. A system supplies a portion of the lubricating oil for the internal combustion engine under pressure to this space through the oil ports, and conduits communicate the oil ports with the supply system.

    摘要： A separate oiling type two cycle engine having a diaphragm type float-less carburetor including a metering chamber and a needle valve comprises a fuel reservoir for reserving fuel, a fuel supply port provided at the fuel reservoir for supplying fuel into the fuel reservoir, a fuel passage for connecting the fuel reservoir with the needle valve, a venturi provided immediately upstream of the needle valve, an oil discharge port provided adjacent to the inlet of the venturi for discharging lubricating oil therethrough so as to mix lubricating oil with fuel, and a fuel return port provided at the higher position than the fuel supply port for returning fuel to a fuel tank. Since lubricating oil is supplied to almost all major components of the carburetor, carburetor components such as a choke valve, a throttle valve, fuel passages, jets, metering needles, nozzles and the like can be prevented from being corroded, rusted or clogged by salt water contained in fuel.
