Is you engine balanced?

Balance matters a lot when speaking about vehicles. This is especially true with your engine, which is subjected to extreme pressure and heat during combustion. Moreover, with all the rotational speeds that induce vibrations to parts, a balanced engine is surely needed to maintain efficiency and reliability.

No engine can however be perfectly balanced because of the amount of subtle factors, though we can improve upon the balance of a mss produced engine. You can do something to maximize the power delivery of the engine, by carrying out some modifications. Nonetheless, you must not overlook the benefits of balancing the engine to sustain higher engine speeds.

If you want to attain balance in your engine, you must focus on 2 main areas. First are the components inside the engine whose weight and features needs to be assessed properly. Second are the forces created within the combustion.

Balancing engine components involves a lot of processes. One is blueprinting, which refers to the matching and machining of components as a set with a unique engine. Like a tyre installer has a special machine to balance your wheels a machine shop have a dedicated engine balancing machine onto which the components fit and rotate.

The main engine components in an engine to be considered for balance are the bearings, flywheel, piston roads, piston and rings, crank, and pins. Weight is removed from the heavier side of each component so that balance is achieved. This factor incrementally increase the imbalance so lighter components are used to get more stability in the engine, though we still have to consider that some light components are weak.

Pistons and rods are usually machined as a matching pair so the weight and dimensions of each is closely matched, making it well on the way to having balanced engine. On the other hand, the crank usually has a metal cut away and sometime weld to adjust the weight.

The crank at the bottom of your engine has a hard task, which includes conversion of the vertical motion of pistons into rotational forces. Crankshafts are forged from steel thorugh they can also be cast from iron. A machined crank from steel can be a lot stronger as the metal has not been subjected to heating and cooling cycles of casting.

After balancing the engine components, you will need to balance the dynamics. If the compression ratio is out between cylinders, there will be imbalance and vibration since the engine turns over. Such ratio can be affected by a large number of factors, hence, the cylinder wall can get damaged later on. Furthermore, weaker gaskets, poor valve seating, and bad spark plug will also come out. It is surely favorable to take compression readings from each cylinder at regular intervals and check that everything is open within an acceptable tolerance. Also check the camshaft since uneven wearing can lead to stuck open valves and imbalanced cylinders.

If each cylinder compression matches, you will need to balance the fueling. The injectors should be matched and must deliver the same amount of fuel to the cylinders. The fuel/air ratio also need to match.

Once the engine is balanced, you will hear a purr as it ticks over. You should get used of the sound of the engine exhaust note on tick over. Once you lose the regular throbbing purr, you must be alarmed about the possibility of imbalance in the engine.

The engine is indeed the most important system in your vehicle. Once perfect balance is lost, other auto systems will soon fail too. To tone down expensive repairs and replacements, make sure that you will sustain the balance in your engine system. You can do it yourself by following simple procedures that are rampantly available in the internet. If you are not so confident in doing so, you can always look for a reliable auto technician.
