6 Cylinder 6640 Diesel Engine Piston
The 6-Cylinder 6640 Diesel Engine typically uses pistons that are essential components in the engine's internal combustion process. The piston's role is to move up and down within the engine cylinder, creating the necessary compression and power generation
Material and Construction: Diesel engine pistons are usually made of high-strength materials, such as aluminum alloy, steel, or cast iron, to withstand the high temperatures and pressures generated during combustion. They are often heat-treated to improve durability.
Ring Grooves: The piston contains grooves for piston rings. These rings are responsible for sealing the gap between the piston and the cylinder walls, preventing the escape of combustion gases into the crankcase and maintaining proper compression.
Crown: The top of the piston, known as the piston crown, is designed to withstand extreme heat and pressure. It is in direct contact with the high-temperature combustion process and must be heat-resistant to avoid damage.
Skirt: The piston's skirt is the lower portion that makes contact with the cylinder walls. It helps guide the piston's movement and provides stability during the engine's operation.
Wrist Pin or Piston Pin: The wrist pin, also known as the piston pin, connects the piston to the connecting rod. It allows the piston to pivot and transfer the linear motion of the connecting rod into the rotary motion of the crankshaft.
Cooling Features: Some diesel engine pistons incorporate cooling features, such as oil jets or internal cooling channels, to manage the piston's temperature and prevent overheating.
Balanced Weight: Properly balanced piston design ensures that the reciprocating mass is evenly distributed, reducing vibrations and minimizing wear and tear on the engine components.

Product Description
1.Low weight and high efficiency.
2.It is more flexible and reliable.
3.It required less maintenance.
4.It is easy to manufacture.
5.The power to weight ratio is high.
6.It generates extremely low vibration because there are no working parts in contact with each other.
7.The lack of any rotary elements (such as a crankshaft) makes it fast to start and stop.
Product Functions
Pistons play a vital role in an automobile engine including the spark ignition gasoline engine and compression ignition diesel engine. These two internal combustion engine process is different but they utilize piston for their processes. Below are the functions of the piston on automobile engine:
1.The major function of piston is to transfer the force output of a small gas explosion in the cylinder to a crankshaft. This provides rotational momentum to a flywheel.
2.It moves forward so that gases can be compressed and explosion can occur for the backward movement.
3.The piston contains a pin called piston pin, it allows the gas in the chamber from escaping.
4.A connecting rod attached to the piston’s bottom allows the mechanical work to be transferred.
5.Pistons help to carry the air-fuel mixture within the period of the combustion cycle.
6.Pistons aid the control of oil flow in the cylinder walls using the oil control ring.
Product Working Principle
Asking how a piston work, you will be exposed to the entire working principle of the internal combustion engine. This is because piston does the major work during the four-stroke cycle.
Just as earlier mentioned, an internal combustion engine is of two types and they work in two different manners. One of it work with a spark plug, hence it’s named “spark ignition engine” and the other “compression ignition engine”. Their working is quite different.
Product Material
Cast iron is the earliest material used for making piston. However modern engine benefits from lighter materials for the engine balancing. Good pistons must be able to resist the engine’s combustion temperatures. Alloys such as Y alloys and hiduminium are specifically used to obtain such properties.
Pistons are made from aluminium alloys with a casting process. Some pistons used in racing vehicles requires better strength and fatigue life which is why they are forged.
Billet pistons are also used in racing engines because they do not rely on the size and architecture of available forgings, making the design to change at dying minutes. Although it’s not commonly visible with the naked eye.
