180°に設定した２シリンダ方式のエンジンの調速
装置に関する。[Detailed explanation of the invention] This invention is a relatively small (displacement of about 250c.c.) mounted on mobile agricultural machinery such as a riding rice transplanter.
This is related to the speed governor of a cycle engine, and in detail, the crank angle is adjusted to reduce vibration.
This relates to a speed governor for a two-cylinder engine set at 180°.
クランク角180°の２シリンダ方式はクランク軸

供給されないことが欠点としてあらわれるもので
あつた。 The two-cylinder system with a crank angle of 180° has the advantage of maintaining the rotational balance of the crankshaft and reducing inertial vibration, but the cycle phase difference between both cylinders is 180°.
As a result, the disadvantages are that the intervals between the explosion strokes become uneven and that the air-fuel mixture is not evenly supplied to the cylinders in use due to the air-fuel mixture due to the overlapping of the intake strokes of both cylinders. It was hot.
ただし、エンジン回転数が3000rpm程度にまで
上がると、爆発間隔の不均一はほとんど問題にな
らず、吸気の不均一だけが問題として残る。 However, when the engine speed increases to around 3000 rpm, the unevenness of the explosion intervals becomes almost no problem, and only the unevenness of the intake air remains.
この本考案は、両シリンダに夫々気化器を接続

First, with the screw 16 loosened, the governor lever main body 8a, the auxiliary lever 8b, and each throttle lever 10, 11 are connected. are connected by rods 12 and 13. Next, the governor lever main body 8a is moved counterclockwise until one throttle lever 10 is fully closed, and fixedly set on the governor shaft 7. After that, adjust the swing of the auxiliary lever 8b so that the other throttle lever 11 is fully closed, and then

た。 As explained in the embodiments above, the present invention connects a carburetor to a two-cylinder engine with a crank angle of 180°, connects each carburetor to a common air cleaner, and connects the carburetor to a common air cleaner. Since a partition plate is provided to divide the intake air into each carburetor, even if the intake strokes of both cylinders partially overlap, it is possible to prevent the air-fuel mixture from being drawn into both cylinders. As a result, it is now possible to reliably supply a predetermined amount of air-fuel mixture from each carburetor independently, maintain stable combustion in each cylinder, and smoothly produce the desired output.

滑な運転を行うことができるようになつた。 In addition, in order to link the throttle lever of each carburetor with one governor lever, a means for adjusting and fixing the relative position of both levers is incorporated into the linking mechanism between the governor lever and one throttle lever. ,
Two throttle levers can be adjusted and set sequentially with respect to a common governor lever, and both throttle levers can be easily and precisely set in sync to equalize the combustion characteristics of both cylinders, resulting in smooth operation with less vibration. I am now able to do this.
