节能是我国四化建设中的一项基本任务,而汽车节能的主要途径在于改善发动机的动力性能和提高发动机的功率.发动机运行中存在着分子机械磨损、腐蚀磨损、磨料磨损,尤其后者更为严重.即使采取了各种措施,而发动机的磨损仍然存在.Q85合金就是弥补气缸磨损,提高发动机性能的专用合 Energy saving is a basic task in the construction of our country’s four modernizations, and the main ways of saving energy in automobiles are to improve the engine’s dynamic performance and improve the engine’s power. There are molecular mechanical wear, corrosion wear and abrasive wear in the engine operation, especially the latter Even if a variety of measures taken while the engine wear and tear still exists.Q85 alloy is to make up for cylinder wear and improve engine performance dedicated
