摘要： PROBLEM TO BE SOLVED: To suppress entry of air fuel mixture to inside of an air cleaner by blowing back on an air fuel mixture passage in a stratified scavenging two-cycle engine.
SOLUTION: The air cleaner 24 has a guide member 30. A blowing back flow 20 of air flowing back to the air cleaner 24 via a first air opening 23A by an air blowing back flow is guided to a portion in the vicinity of a second air opening 23M by the guide member 30. A blowing back flow 21 of air fuel mixture generated on the air fuel mixture passage 2 before the blowing back phenomenon on an air passage 3 collides with the air flow 20 flowing toward the portion in the vicinity of the second air opening 23M, and thus, the air fuel mixture is stopped in the vicinity of the second air opening 23M.

摘要： PURPOSE:To increase the output of an engine, by promoting atomization of fuel by forming a plurality of parallel intake passages by vertically dividing the intake passage on the downstream side of a throttle valve constituting a variable venturi carburetor, and opening the plurality of parallel intake passages successively along with downward movement of the throttle valve. CONSTITUTION:At the time of high-load operation of an engine, a piston-like throttle valve 6 is in its upper position, so that a primary in-take passage 18 and a secondary intake passage 20 of an intake passage 12 divided by a partition wall 16 are both fully opened. Resultantly, a large amount of intake air is passed through the passages 18, 20. Here, since the effective jet area of a main jet 10 is large, a large amount of fuel is also ejected from the main jet 10 and air-fuel mixture is supplied to a combustion chamber 26 via a crankcase 14 and a scavenging passage 22. At the time of low-load operation of the engine, on the other hand, the throttle valve 6 is in its lower position, so that only the primary intake passage 18 is opened. Resultantly, all of intake air is introduced into the primary passage 18 and the velocity of intake-air flow is increased, so that sufficiently atomized fuel is supplied to the combustion chamber 26.
摘要翻译：目的：为了增加发动机的输出，通过在构成可变文丘里化油器的节流阀的下游侧垂直分割进气通道并形成多个平行的进气通道来促进燃料雾化，并且打开多个平行进气口节流阀连续向下运动。构成：在发动机的高负载运转时，活塞式节气门6处于其上部位置，使得进气通道12的主要吸入通道18和次级进气通道20除以分隔壁16都完全打开。结果，大量的进气通过通道18,20。这里，由于主喷嘴10的有效喷射面积大，所以主喷射流10和空气 - 燃料混合物也喷出大量的燃料经由曲轴箱14和扫气通道22被供给到燃烧室26.另一方面，在发动机的低负载运转时，节流阀6处于其较低的位置，使得仅一次进气通道18打开。结果，所有的进气都被引入到主通道18中，并且进气流的速度增加，使得足够雾化的燃料被供应到燃烧室26。

摘要： PURPOSE:To prevent separated liquid fuel from collecting in the tank in such a way that an air inlet path in an engine and a surge tank which maintains fluidic inertia of the mixed air are communicated by a branch pipe which has asperities on the inner wall surfaces. CONSTITUTION:An air inlet path 6 which is provided with a carburetor 15 is communicated through a reed valve 13 to an air inlet port 7. An expansion tank 21 is communicated as a surge tank thrugh a branch pipe 20 at the upper part of the air inlet path 6. Asperities are formed on the wall surfaces of the branch pipe 20. Therefore, separated liquid fuel in the tank 21 can be returned along the inner wall surfaces to the air inlet path 6 without being pushed back into the tank 21 by the mixed air flow which is taken in through the branch pipe 20.
