ABOUT THE CYLINDER LINER:

PISTON STRUCTURE:

The entire piston can be divided into three parts: the piston top, the piston head and the piston skirt.
The main function of the piston is to withstand the combustion pressure in the cylinder and transmit this force to the crankshaft through the piston pin and connecting rod. In addition, the piston also forms a combustion chamber together with the cylinder head and the cylinder wall.

The top of the piston is a component of the combustion chamber, and thus often has different shapes. The top of the piston of the gasoline engine adopts a flat top or a concave top, so that the combustion chamber has a compact structure, a small heat dissipation area, and a simple manufacturing process. The crown piston is commonly used in two-stroke gasoline engines. The piston crown of a 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 crankbox and preventing the oil from entering the combustion chamber. Most of the heat absorbed by the top of the piston also passes through the piston head. The part is passed to the cylinder and passed through the cooling medium.
The piston head is machined with a number of ring grooves for mounting the piston ring. The number of piston rings depends on the sealing requirements and is related to the engine speed and cylinder pressure. High-speed engines have fewer rings than low-speed engines, and gasoline engines have fewer rings than diesel engines. The general gasoline engine uses two gas rings and one oil ring; the diesel engine has three gas rings and one oil ring; the low speed diesel engine uses three to four gas rings. In order to reduce the friction loss, the height of the endless belt should be reduced as much as possible, and the number of rings should be reduced under the condition of ensuring the seal.

CYLINDER LINER :

The engine piston, piston ring, piston pin, cylinder sleeve and connecting rod copper sleeve, circlip, cylinder sleeve water blocking ring are called cylinder liner components (commonly known as four matching, six matching, seven matching). It is the moving component of the engine. It cooperates with the fuel system and the valve train to complete the engine intake, compression, combustion work and exhaust stroke, and converts the chemical energy into mechanical energy to output the power. Because it is subject to strong mechanical and thermal loads, it is the most important and most vulnerable component of the engine.
