“…For the structure parameter of the single cylinder engine in this article, see table 1. The parameters in table 1 may calculate out the movement mass for up-down reciprocating of piston crank is m J =0.27493kg, and total mass of eccentric exercise m Z =0.4383kg [3].Ecessive balance is used for original engine. By observation the design of crank balance block, we know that the mass center of balance weight of original engine is not at central line, and the gravity of two elements may be detected by PRO/E software, and the gravity of right/left balance block of original engine rests 16.5mm and 6.39mm away from central line.…”

At present, excessive balance is used for the balance of traditional single cylinder engine. Single shaft balance may also be used on single cylinder engine with large power and high rotation speed. In this article, a small single cylinder engine 250 is studied. By our research, the mass centre of excessive balance block is not at one straight line with the central line of cylinder to result in heavier horizontal vibration of whole machine. In this article, a modification scheme is offered. In this scheme, for more reduction of vibration, a balance device for single shaft is designed for machine, and find out reasonable installation place by optimization method such that the impact of additional torque, arising from the balance of single shaft, to vibration of whole machine may be reduced to min level to realize balance optimization of the machine.
