摘要
采用高强度灰铸铁(HT300)和蠕墨铸铁材质,以LR系列柴油机4M缸体为突破点,优化缸体结构,提高缸体的整体强度,目的是在现有机体缸心距和结构保持不变前提下提高机体整体强度,在减少油耗和排放量的同时提高比功率。
Use of high strength gray cast iron(HT300)and vermicular cast iron,LR series diesel engine cylinder 4M as the breakthrough point,the optimization of cylinder structure,improve the overall strength of the cylinder,the purpose is to improve the overall strength of the body in the existing cylinder core distance and structure remain unchanged under the premise,and improve the specific power while reducing the fuel consumption and emission.
