PURPOSE:To increase the engine torque by providing a drive shaft and power take-out shaft with shaft center positions displaced with each other and connecting crankshafts for both shafts with a linkage. CONSTITUTION:A drive shaft 1 having a crank arm 3 connected to a piston rod 7 and a shaft having a flywheel 10 are provided. The crank angle for crankshafts 5, 9 are set to be approximately 15 deg. and approximately 60 deg. in relation to the vertical. The pressure stroke of a piston is done with the crank arm 3 at approximately 15 deg. in relation to the top dead point P. At this time, a crank arm 4 is maintained at approximately 60 deg. at all the time through a link 8. The force acting upon the crank arm 4 is nearly tangential to a circle described by the crank arm 4, and so the heavy flywheel 10 can easily be rotated. |
