Weighing apparatus,
It so although these above-mentioned patents are directed to the balance of engine, but is mostly to be solved by way of tensioning wheel
Certainly, all do not propose how to solve that existing balance mechanism volume is big, and structure is complicated, the at high cost and bigger problem that takes up space,
Therefore all still there is mentioned-above deficiency, still need further to be improved.
Summary of the invention
It is an object of the invention to uneven in unilateral stress for available engine crank pulley, engine is flat
Weigh excessively complicated, the bulky deficiency of device, proposes a kind of novel engine balance method, the engine balance method is not
It only can solve non-uniform phenomenon of the balanced engine crank pulley in unilateral stress, so that having effectively to avoid
The deformation of the engine suspension soft pad generated due to engine discontinuity, and the bracket due to caused by unbalance stress
Deformation；Also can check to a certain extent since engine generates the hair of cooling system caused by displacement, air inlet system and exhaust system failure
It is raw.
In order to reach this purpose, the present invention provides a kind of sides of balanced engine crank pulley unilateral side unbalance stress
