CRANKSHAFT AND PISTON ARRANGEMENT

摘要

PURPOSE: The crankshaft and piston arrangement(10) for a combustion engine are to keep a balance of engine consisted of single cylinder or two. CONSTITUTION: The crankshaft and piston arrange comprise a piston(12) pivotally connected to a crankshaft(18) by a connecting rod(14).The balance means comprises a connecting rod(26) and a balance arm(32,a, b, c). The balance arm is connectable at an end remote from the connecting rod to the engine and provides a balance mass thereby to balance vibrational forces created by the movement of the piston(14).
