一、前言马伊巴赫工厂设计和制造高速汽油机和柴油机已有几十年的历史了。在设计制造过程中,除了注意提高功率和降低油耗外,还特别注意耐久性和可靠性,为了满足后一要求,设计了一种具有圆盘曲轴的“隧道式结构”,如今成了马伊巴赫柴油机的特征标志。这种隧道式结构不仅综合了国内外铁路在运用机动车中所积累的经验,而且也运用了从六万台马伊巴赫工厂制造的300至700马力各种其他用途的发动机中所获得的知识(这种发动机同样具有带滚柱轴承的圆盘曲轴)。
I. INTRODUCTION The Maiba Plant has been designing and manufacturing high-speed gasoline and diesel engines for decades. In the design and manufacturing process, in addition to paying attention to improving power and reducing fuel consumption, special attention was given to durability and reliability. To meet the latter requirement, a “tunnel-type structure” with a disc crankshaft was designed and now it has become a horse Bach diesel engine characteristic sign. This tunnel structure combines not only the experience gained by domestic and foreign railways in the use of motor vehicles but also the knowledge gained from engines ranging from 300 to 700 hp for a variety of other purposes from the 60,000 Maibaher plant (This type of engine also has a disc crankshaft with roller bearings).
