Engine primary and secondary balance
WebPrimary and secondary forces are well balanced. This is a smooth engine. This allows for less weight on the crankshaft, resulting in less power lost to rotational inertia. Low centre of... WebSep 6, 2024 · The primary unbalanced force is: FP = m × ω2 × r × cosθ Secondary unbalanced force is: ω θ F S = m × ω 2 × r × cos 2 θ n The primary unbalanced force is maximum when θ = 0° or θ = 180°. Thus, the primary force is maximum twice in one revolution of the crank. The maximum primary unbalanced force is given by Fp (max) = …
