• Wear-resistant material: It is made of alloy material with excellent wear resistance, which can effectively resist the friction caused by the high-speed reciprocating motion of the piston in the cylinder, and has good wear resistance, earthquake resistance, impact resistance, corrosion resistance and long service life.
• High-temperature stability: it can still maintain stable physical and mechanical properties in the high-temperature environment in the engine combustion chamber, and will not be deformed or invalid due to high temperature, ensuring the reliable operation of the engine under various working conditions.
• Efficient seal: It can form a good seal between the piston and the cylinder wall, effectively prevent the high-temperature and high-pressure gas in the combustion chamber from leaking to the crankcase, improve the compression ratio of the engine, enhance the power output, and make the vehicle accelerate more powerfully.
• Accurate dimensional tolerance: the dimensional tolerance is strictly controlled during manufacturing, and it is accurately matched with the piston and cylinder, so as to ensure that a good seal can be achieved after installation, and excessive friction resistance will not be generated, thus improving the overall performance of the engine.
