Description


The piston can be divided into three parts: piston crown, piston head and piston skirt. The main function of the piston is to bear the combustion pressure in the cylinder and transmit this force to the crankshaft through the piston pin and connecting rod. The piston, cylinder head and cylinder wall form a combustion chamber. The piston top is a part of combustion chamber, so it is often made into different shapes. The piston top of gasoline engine mostly adopts flat top or concave top, so as to make the combustion chamber compact in structure, small in heat dissipation area and simple in manufacturing process. Crown piston is commonly used in two stroke gasoline engine. The piston crown of diesel engine is often made into various pits. The piston head is the part above the piston pin seat. The piston head is equipped with a piston ring to prevent high temperature and high pressure gas from entering the crankcase and oil from entering the combustion chamber.

Most of the heat absorbed by the top of the piston is also transmitted to the cylinder through the head of the piston, and then transmitted through the cooling medium. The piston head processes several grooves for installing piston rings. The number of piston rings depends on the requirements of sealing. It is related to the engine speed and cylinder pressure. All parts below the piston ring groove are called piston skirts. Its function is to guide the piston to and fro in the cylinder and bear the side pressure. When the engine is working, the piston will be bent and deformed due to the gas pressure in the cylinder.

After the piston is heated, the expansion of the piston pin is larger than that of other parts due to the large amount of metal in the piston pin.

The piston will also produce extrusion deformation under the action of side pressure. The comprehensive result of the above deformation makes the piston skirt section become the ellipse of the long axis in the direction of the piston pin.

Development history


1,  The first automobile engine piston in the world was made of cast iron.

2,  Aluminum alloy materials with its light weight, good thermal conductivity and low expansion coefficient were favored by automobile engine enterprises and began industrial manufacturing.

3,  With the rapid development of high horsepower automobile engine, especially the application of turbocharging and intercooling technology in heavy diesel engine. 

4,  As well as the continuous improvement of the requirements of high compression ratio and low emission in large cylinder diameter, the traditional aluminum alloy piston material can not meet its use requirements.

5,  The first carbon steel piston was used in the single cylinder diesel engine of elspett company of Germany in 1955, and began to produce carbon steel piston in batch for caterpillar of the United States in 2000.

6,  At present, carbon steel piston has been widely used in high-performance medium and heavy-duty diesel engines of man, caterpillar, Cummins, Daimler, Volvo, Benz and other companies.

7,  After heavy commercial vehicle and racing engine, carbon steel piston is gradually used in passenger car diesel engine in European and American countries, with a wide range of application scenarios.
