Cylinder liner industry future development characteristics

Internal combustion engine industry in the development of dongfeng, cylinder market expanded rapidly in our country. China internal combustion engine industry association, the cylinder liner industry overall quality level, improve technical level, production continued rapid growth. Rapid development in recent years, with the internal combustion engine industry in our country, its supporting industries, there is a thriving scene, cylinder industry is one of them. Cylinder is the key to the internal combustion engine parts, high performance, high quality and low consumption is the standardized requirements, and adapt to the demands of the development of internal combustion engine industry. At present, the domestic industry in the cylinder material diversification, rapidly improve reliability, quick update the three characteristics. Generally USES alloy cast iron cylinder material, alloy material can not meet the internal combustion engine before upgrading requirements for reliable and wear-resisting. Now, as technology advances, cylinder materials with each passing day. Its material used more wear resistant cast iron, such as boron cast iron, high phosphorus cast iron are new cylinder liner material, its abrasion organization are respectively boron compounds, such as phosphorus eutectic material. Different chemical elements, cylinder liner mechanical strength, wear resistance is different. Bainite cast iron cylinder sleeve material, is currently the most advanced has higher strength and hardness, better toughness and wear resistance, so as to prolong the service life of the cylinder liner, and satisfies the requirement of internal combustion engine manufacturer is increasing day by day the overhaul period. In terms of improved reliability, the main problems in the cylinder liner is corrosion and wear. Therefore, the progress of the material also need to the development of surface treatment technology, the two work together to make the reliability of the cylinder liner to the next level. At present, the technology of the cylinder liner surface treatment with chrome plating, thermal spraying, etc. Add some rare element to surface treatment, can enhance the wear resistance of cylinder liner and oil storage rate, avoid cylinder, to meet the need of the development of internal combustion engine. Laser surface treatment technology is a kind of economic and effective technology, which USES laser scanning cylinder liner, make its surface metal rapidly heated to a certain temperature, then make its rapid cooling, can significantly improve the wear resistance and service life of cylinder jacket. As the important parts, cylinder liner upgrading of products to keep up with the speed of internal combustion engine upgrades. Today, the whole environment presents the high-speed development of science and technology, the original internal combustion engine body is bigger. In order to meet the consumer demand, internal combustion engine is a trend of small volume, lightweight development. The distance between the cylinder and the cylinder is more and more small, cylinder liner process apparently also want to adapt to this trend, and the thick wall cylinder liner is to develop in the thin wall cylinder liner, the latter is more high quality, high efficiency, energy saving. Thin wall cylinder liner on light vehicles will become an upgraded version of internal combustion engine cylinder liner.
