Abstract
The present application discloses a first-order balancer of an internal combustion engine comprising forward-rotating fly-wheels fitted on both ends of a shaft and allowed to rotate in the same direction as said shaft, backward-rotating fly-wheels fitted respectively on said both forward-rotating fly-wheels and allowed to rotate in the opposite direction from said both forward-rotating fly-wheels, forward-rotational counterweights placed on said both forward-rotating fly-wheels, and backward-rotational counterweights placed on said both backward-rotating fly-wheels and having a different weight from said both forward-rotational counterweights. According to the first-order balancer of an internal combustion engine of the present invention, vertical and horizontal first-order unbalanced moments arising in an internal combustion engine may be simultaneously balanced.
