The structure of the piston
Update:2017-02-04 Tags:the

Structure can generatorbe divided into the top of the piston, ring groove and the skirt of three parts, as shown in figure 3-17. The top of the piston and cylinder head, cylinder jacket of the combustion chamber, ring groove is designed for the installation of piston ring.

The top 1,

Piston at the top and the cylinder head and cylinder jacket of the combustion chamber, the structure of switch is related to the chosen form of combustion chamber. Diesel engine piston top is concave, its shape is according to the form and way of mixture formation and combustion chamber design. Different types of diesel engine piston at the top of the shape is different, with series diesel engine piston at the top of the shape also has a lot of this difference. When change the piston must choose the same shape, same weight of the piston.

2, ring groove

Piston ring groove of the department is also known as leakproof department or department, department under several ring grooves cut (i.e., oil and gas ring groove ring groove), is dedicated to the installation of oil and gas ring ring. Upper are commonly used to install gas ring, the purpose is to prevent high temperature gas into the crankcase, and parts of the piston absorbs heat to the cylinder walls. The lower ring groove used to install the oil ring. In many oil ring groove on the bottom of the radial holes, make the oil ring from cylinder wall cut off the excess oil, via holes flow back to the crankcase.

3, the skirt

The following section ring grooves are called skirt. Piston skirt of direct contact with the cylinder wall and guiding role on the movement of the piston. Pin hole in piston skirt has dedicated to the installation of piston pin. Inside the pin hole each have a circlip groove, when the piston pin into the pin hole, then spring into the groove, respectively, the purpose is to prevent the piston pin up move.
