    • An intake passage for an internal combustion engine is provided on the downstream side of a throttle valve with a fuel injection nozzle connected through a fuel passage to a fuel pump and is additionally provided on the upstream side thereof with an air metering valve arranged to be turned towards its opening side according to increase in an intake negative pressure, and the fuel passage is provided with a fuel metering valve interposed therein. The fuel metering valve is formed into a slidable type spool valve, a valve body thereof is disposed in parallel with a valve body of the air metering valve and a lever is swingably supported at its middle portion and is in engagement at its one end with a cam mounted on a turning shaft of the air metering valve and is in engagement at its other end with a valve rod projecting from one end portion of the fuel metering valve.

    • An internal combustion engine having a plurality of in-line cylinders is provided with a series of exhaust pipes each connected to receive exhaust gases from one or more of the cylinders. A first reaction chamber receives exhaust gases from each of the exhaust pipes. A second reaction chamber extends along a first reaction chamber parallel with the line of cylinders, and has a wall in common with the first reaction chamber. A third reaction chamber surrounds and encloses the first and second reaction chambers and the exhaust pipes. An opening between the first and second reaction chambers is positioned near one of the exhaust pipes at the end of the series, and another opening between the second and third exhaust reaction chambers is positioned near an exhaust pipe at the other end of the series. This construction minimizes temperature drop in the long exhaust pipes at the ends of the series. Exhaust gases from the engine are held at high temperature for long residence time to oxidize HC and CO and thereby minimize discharge of these unwanted emissions into the atmosphere.
    • 具有多个直列气缸的内燃机设置有一系列排气管,每个排气管被连接以接收来自一个或多个气缸的废气。 第一反应室从每个排气管接收废气。 第二反应室沿与第一反应室平行的第一反应室延伸,并具有与第一反应室共同的壁。 第三反应室围绕并包围第一和第二反应室和排气管。 第一反应室和第二反应室之间的开口位于串联端部的排气管之一附近,第二和第三排气反应室之间的另一个开口位于串联另一端的排气管附近。 这种结构使串联末端的长排气管的温度降低最小化。 来自发动机的废气保持在高温下长时间停留以氧化HC和CO,从而使排放到大气中的这些不需要的排放物最小化。
