The Uses of Piston Rings
Piston rings are the rings that seal the gap between a ring and the cylinder and are mostly used for mechanical work and in cars. A piston ring is an open ended ring that fits into a groove or outer diameter of the cylinder. As far as cars go, basically, piston rings have three major functions which are to seal the expansion chamber, support heat transfer and finally, regulate the engine oil consumption.
Most automotive pistons have 3 rings with the top two controlling the oil while also acting as a sealing object as the lower one acts as controller of the oil supply in to the liner which acts as lubricant to the pistol. Oil controlling rings have typically three types: cast iron rings, spring backed oil rings and multiplies oil control rings. When fitting new piston rings end gaps are to be paid attention to. The ring is not continuous but is broken at one end of its circumference. The gap may be checked by putting a bore in between those two gaps and the end gap should always be within the recommended limit.
When fitting a new ring to a used engine, ‘ridge doger’ rings are sometimes used for compressing without reboring the cylinder. There all kinds of piston ring suppliers all over the world. To name a few, there is Windsor Export and one of the best known and most reputable is Honda who is known not only for their cars and trucks but also their top of the line engines and parts.
Piston rings are used by a variety of industries. Firstly it is used in automobiles and its common secondary use is on steam engines. Earlier piston rings were very different from what technology has given us today. The modern piston rings have steel based body with an annular shape and an outer peripheral face.
When not properly cared for there can be various problems that arise with piston rings. An improperly lubricated shaft will result in damage being done to the piston rings. As long as they are properly cared for an treated though, piston rings can last a long time and problem free thanks to being made to tolerate a high level of wear and tear –precisely the reason they are used in the making and maintenance of cars. The reason that they are so durable likely has to do with the fact that they are generally made from zirconium metal. Another advantage of these rings are that even under high thermal load it does not suffer from thermally induced destruction or welding of piston ring groove. This is because due to its homogenous structure it avoids the problem of metal bonds of piston rings.
Nowadays there really is a huge variety of piston rings; some with iron alloys, other made of steel—all of which stand up much better than earlier piston rings. Good quality piston rings will guarantee breakage resistance, reduced ring side wear, reduced groove side wear, improved heat resistance, and a longer service life.
A little research can help you in choosing the right piston rings for your automotive needs. Note though that only trained professionals should be responsible for installation in order to avoid any malfunctions or even accidents.
