The centerline parallel of first crank.
Further, the center line in the balance portion and the central axis of the balance shaft.
Further, in addition to connecting rod；Described connecting rod one end is connected with outer inside casing piston, and the other end passes through the bent axle
Pin is connected with first crank with second crank respectively, and drives first crank and the second crank to rotate.
Further, the connecting rod is arranged between first crank and the second crank, and positioned at the crankpin and
The top of balanced component.
Compared to prior art, the utility model is shaken by setting balanced component in the first crank and the second crank
When dynamic, using vibrations power caused by balanced component come balance vibration, avoid the first crank and the vibration of the second crank and draw
The vibration of engine other assemblies is sent out, vibrating noise is reduced, strengthens stability, improve the performance of engine, extend
The life-span of engine.
