With the growing needs of the engineering industry, there have been many updations since the invention of the steam engine. The pins and rings that were used then has changed significantly with time and upgraded with new features and specifications. Piston pins and Piston rings have been in use since 1854. In the 21st century, they are used with the upgraded feature and easy to use. Makes less noise, creates combustion on the go and very safe to be used.

Before moving ahead with the rings and pins, let's know what a Piston is?

A piston is a cylindrical engine component which moves back and forth in the cylinder. It produces force during the combustion process. These are mainly used for engineering purpose. piston pin and rings both are a part of Piston. They play a vital role in Piston, without them functioning of a piston is almost impossible.

Purpose of piston pins

Piston pins are used in the high-performance supercharged tractor, automobile and locomotive engines. They are done of carburized ...
... alloy steel. These pins are used for aligning, mounting, assembling and penetrating two different pieces. These pins are categorized into different categories. We can talk about it in some other article. Piston rings are mainly used for sealing cylinders. These rings can work at a higher temperature in comparison to fabric, polymer seals and elastomeric.

Purpose of piston rings

Seals the combustion chambers from any leakage during the combustion process. A compression ring is a piston ring located in the ring groove which is closest to the piston head. Piston rings have been significant are for development for an internal combustion engine. Piston rings create friction in the engine which is as much as 24%. When there is an increase in friction this means this is a result of design compromise to achieve good sealing and long lifetime, The main function of a piston ring is to seal the gas so that there's no leakage. Multiple rings can achieve these sealing with different functions which are used through metal and metal sliding contact.

Most automotive pistons have 3 rings, compression ring, wiper ring and oil ring. They do control oil also primarily used for combustion sealing. Mainly the lower ring controls the supply of oil to the liner lubricating the piston skirt and the compression rings. Wiper ring also known as backup compression ring. In most pistons and cylinder, you will find two rings only.

Piston rings are generally loose in fitting in the cylinder. If it is tight in nature, it can cause severe damage to the engine. These rings are not a very expensive part of the cylinder. But if you want to replace it and fit new ones then they are a bit expensive compared to the one which is installed beforehand. Labour costs are a major factor while fitting them. The labour needs to dismantle the large part of the engine while fitting it and again he will mantle the engine. But surprisingly the two-stroke engines which you will find in motorcycles, piston ring replacement is very easy and quick to install or replace.

The India Piston Ring has been into manufacturing the top class piston rings, cylinder sleeves and different types of engine parts. It has been making the types of parts of the engine and also its subparts, for a number of decades now, using the best in class and state-of-art technology to manufacture the products.
