Piston engines are subject to cyclic vibrations due to the motion of the crank and pistons inside the engine. The vibrations are most obvious in single cylinder engines. As the number of cylinders is ...

Two balancer developments are followed through the conception and development stages into production. One design utilizes gear driven auxiliary flyweights, and the other, an oscillating counterbalance ...

When you consider the crazy monkey motion of reciprocating internal combustion engines it is remarkable they work as well as they do. You have eight pistons and connecting rods doing a “do-si-do” ...

For an engine to survive all the rocking and rolling it produces, those forces need to be counterbalanced with equal—or at least nearly equal—forces. Today, most production-car engines with more than ...
