Engine Piston Materials
The piston is a fundamental component in the engine, playing a pivotal role in the internal combustion process.
Pistons in internal combustion engines are typically made from aluminum alloys. Aluminum is commonly used because it is lightweight, has good thermal conductivity, and can withstand the high temperatures and pressures inside an engine cylinder. In some high-performance applications, pistons may also be made from other materials such as steel or forged aluminum for increased strength and durability.
Phosphate Coating for Pistons
Metal phosphates form crystalline or amorphous coatings that have good oil bonding, high adhesive strength and good deformability characteristics. Phosphates provide effective protection against seizing and scuffing.
Piston Ring Materials
Piston rings are typically made from durable and heat-resistant materials to meet the demanding engine operation requirements. The most common materials used for rings include:
1, Cast Iron: Fragile piston ring material properties, best used for stock engine builds due to low tensile strength. Low cost, great option for a budget rebuild.
2, Ductile Iron: Stronger piston ring material properties with double the tensile strength of gray iron rings. Better option for performance engine builds.
3, Steel: Better tensile strength and fatigue strength over ductile iron rings. Better option for boosted and nitrous applications. Used in narrow ring width applications for better sealing and less blow-by.
Function of Piston Ringss
The primary function of piston rings is to create a tight seal between the piston and the cylinder wall. They are circular metal rings installed around the outer diameter of the pistons. Here are the main functions of piston rings:
The piston rings ensure that the compressed gases do not leak past the piston and escape into the crankcase, maintaining high pressure and promoting efficient combustion.
They prevent excessive engine oil from entering the combustion chamber and being burned with the air-fuel mixture.
These act as heat conductors to transfer heat from the piston to the cylinder wall and dissipate it into the different engine’s cooling system types.
The rings help stabilise the pistons while moving up and down in the cylinder to prevent excessive vibration and ensure smooth engine operation.
