8. GOVERNOR 8-1 CONSTRUCTION and OPERATION In the model EC05-2, 07-2, 10, 17 and 25-2 engines, a centrifugal flyweight type governor is used. The governor plate complete, governor sleeve and governor arm are installed in the governor chamber (EClOD, lev, 17D and 25-2D), in the crank- case (EC05-2D, 07-2D) EC05-2, 07-2, by the mixture fuel). or in the reduction chamber (type B and V), and lubricated by the lubricating oil (in the model As the engine speed fluctuates, flyweight on the governor plate complete, rotating together with the crankshaft, changes its opening angle and moves the governor sleeve, which in turn rotates the governor shaft through the governor arm. gover- The nor lever is connected to the extending part of the governor shaft and this governor lever is connected to the carburetor throttle lever through the governor rod at the other end; thus the throttle valve is opened or closed and engine speed and output are controled. When the crankshaft rotation increases, all the relevant members move in the direction indicated by-marks and the carburetor throttle valve closes, reducing the fuel supply and consequently reducing the speed and output. When the crankshaft rotation decreases, the same members moie in the direction indicated by-- --marks and the carburetor throttle valve open, increasing the fuel supply and consequently recovering the failing speed and output.
