Engine Balancing

Engine Balancing Information

An engines balance refers to the motions of the internal components of an internal combustion engine. Engines, due to their inherent nature will cause some vibrations. Engine balancing are techniques that are used to reduce motions, vibrations and other stresses that can otherwise compromise the engines performance, efficiency and reliability.

Unnecessary vibrations in the engine are usually caused by uneven firing patterns from pistons in the engines cycle. For engines with more than 2 cylinders there are a number of different possible configuration for which they can be set. Engines that have an odd number of cylinders in each bank suffer the most vibrations. For example a V6 engine, regardless of the V-angle is always going to suffer from dynamic imbalance which causes an end to end rocking. These have to offset by adding counterweights on to the crank shaft and a counter rotating balance shaft to compensate for the rocking motion. This would differ from a flat 6 arrangement when the cylinders mirror each other and can compensate the motions itself.

Engine balancing should be carried out by trained professionals who will know exactly how to use their skills and expertise to obtain the best performance from each engine they work on. Many engine balancing companies will also offer upgraded parts for an engine to help it run better. These can include lighter and more efficient parts.
