6D125 6D125-1 Diesel Engine Piston 6150-31-2112 6150-31-2012 For KOMATSU
Specification
1, What is the function of the automobile piston? The piston is an important component in the automobile engine and one of the most severe working conditions of the key components in the engine. Its main functions are:
1. Bear gas pressure and transmit it to the connecting rod through the piston pin, driving the crankshaft to rotate.
2. As a component of the combustion chamber, it is combined with the cylinder head and cylinder wall to form the combustion chamber.
2, The structural composition of the piston is mainly composed of three parts: the piston crown, piston head, and piston skirt:
1. The piston crown is a component of the combustion chamber, and is often made into different shapes. In gasoline engines, the piston crown is mostly flat or concave to make the combustion chamber structure compact, with small heat dissipation area, and simple manufacturing process. The convex piston is commonly used in two-stroke gasoline engines. The piston crown of diesel engines is often made into various pits.
2. 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 piston head, and then through the cooling medium.
3. All parts below the piston ring groove of the piston skirt are called the piston skirt, which is used to guide the piston to make reciprocating movement in the cylinder and bear the side pressure. When the engine is working, the piston will be bent and deformed due to the effect of the gas pressure in the cylinder. After the piston is heated, because there is more metal at the piston pin, its expansion is greater than that at other places. In addition, the piston will also experience compression deformation under lateral pressure. The comprehensive result of the above deformation causes the cross-section of the piston skirt to become an ellipse with the long axis perpendicular to the direction of the piston pin.
