Remember that a wedding ring is a symbol of love. Your love, so only you decide how it will be! Do not listen to anyone except your soulmate and your heart. Skip past the "folk sayings" and then your wedding will be magical!

The very first material used in the manufacture of piston rings was ductile iron. It is ideally combined with ordinary cast iron. The latter is used in the design of cylinder blocks. Special pores in the structure of cast iron have a positive effect on wear and retain excess oil. In addition to malleable cast iron, ductile iron is also common, which differs from others in its ability to elastic deformation, and this greatly facilitates the installation of rings.

According to their functionality, piston rings are divided into two types: compression and oil scraper. Buy piston rings of any variety and at the most affordable price.

Gas gusts from the combustion chamber should be limited to the first variety. If their position is free, then the inner diameter of the cylinder will be less than the outer one, therefore a certain area of ​​\u200b\u200bthe ring is cut off. The cut is the castle.
The second variety is designed to prevent the penetration of the lubricant component into the combustion chamber. They are equipped with slots and are installed lower than the first variety.

The use of narrow rings is a special direction in the design features of quality pistons. Thin varieties are designed to reduce the friction force formed between the rings and the coating of the cylindrical surface. They are also designed to prevent the occurrence of vibrations under the condition of high engine speeds. It is important to take into account one point: such rings can cause early wear due to critical temperatures and forces that affect the walls. The wear process affects the cylinders themselves and the front area of ​​the rings.

The role of a significant parameter when using special pistons is the design feature of the upper rings. Improvement in engine performance can be achieved with the top ring being at the maximum height allowed. This result can be achieved by capturing smaller volumes of non-free gases with the help of a special bridge between the annular elements. If the rings are located extremely close to the peak piston portion, there is a possibility of deformation due to the extreme temperature rise of the thin web above the annular groove.

Under operating conditions of increased rigidity, the upper piston ring and the bridge over the special groove come into action. The main role performed by the upper ring under conditions of high pressure and extreme temperatures is to ensure a quality seal of the working surface. When implemented will be approx. million cycles, an important indicator for the ring will be the ability to seal and maintain elasticity. The named features of piston rings are determined by the production technology and the characteristics of metals. The type of material that is used to make the ring must meet such parameters as low coefficient of friction and wear.
