前言X105系列柴油机是1966年初开始设计的.先后设计和试制过从直立单缸到V形12缸、既有水冷,也有风冷的十余种机型.1976及1977年产量最高时为80多万马力(约3万台).近年来,批量生产的品种主要是直列水冷2,4,6缸.国家为了装备X105系列柴油机生产厂、历年来作了大量投资,例如,南昌柴油机厂有机体自动线,曲轴、连杆、齿轮室、飞轮壳等大件均有流水线,生产已有了相当的基础.为了满足国民经济发展的要求和赶上国内外柴油机技术水平的进步,X105系列柴油机必须更新换代,才能生存和发展.X105系列柴油机由于当初考虑水风冷通用,缸心距较大(L=140mm,L/D=1.33),因而具备扩缸的潜力,多年来,我所就设想做这一件工作.从1979年9月开始,我所与河北省石家庄柴油机厂及承德柴油机厂等合作搞扩缸研制工作.
Foreword The X105 series diesel engine was designed from the beginning of 1966. It has successively designed and piloted more than 10 models ranging from vertical single cylinder to V-shaped 12-cylinder, both water-cooled and air-cooled, with more than 80 in 1976 and 1977 In recent years, mass production of the species are mainly inline water-cooled 2,4,6 cylinder .In order to equip the X105 series diesel engine manufacturing plant, made substantial investments over the years, for example, Nanchang Diesel Engine Factory organism automatic line , Crankshaft, connecting rod, gear room, flywheel shell and other large parts have pipeline, production has been a considerable basis.In order to meet the requirements of national economic development and to catch up with the technical level of domestic and foreign diesel engine advances, X105 series diesel engine must be replaced In order to survive and develop.X105 series diesel engine because of the original consideration of air-cooled common, larger cylinder center distance (L = 140mm, L / D = 1.33), so have the potential to expand the cylinder, A job since 1979 September, I and Shijiazhuang, Hebei Province Diesel Engine Factory and Chengde Diesel Engine Factory and other cooperation in expanding cylinder research and development work.
