    Assuming all three cranks are on the same axle a pretty good degree of static balance can be obtained. However the three cranks being distributed along what is essentially a shaft creates dynamic couple ; although the degree of hammer-blow is nowhere near that of a conventional two cylinder engine.
    Most of this advantage of three cylinders is lost if divided drive is employed.
