引言工程技术不断地在发展,其发展水平取决于市场需求的变化和技术上的进展。此外,还取决于制造厂和用户在经济上的考虑。根据这些情况,例如本文所述的产品(大型柴油机)一开始就在一个国家中用来作为机车的动力。自从低速、中速、高速柴油机这几个术语成为今天的惯用语以来,这种分类只是根据它们的额定转速而定,这里想详细谈谈高速柴油机的情况。然而,据说中速柴油机和高速柴油机作为铁路牵引动力,其质量同样已得到证实,因此对它们的使用可靠性和寿命无须再论高低。考虑到国际机车市场的需求,作为机车牵引动力的中速柴油机组或高速柴油机组都能适
Introduction Engineering technology continues to develop, the level of its development depends on changes in market demand and technological progress. In addition, depends on the economic considerations of the manufacturer and the user. Depending on these circumstances, for example, the products described here (large diesel engines) were initially used in a country as the locomotive’s power. Since the term low-speed, medium-speed and high-speed diesel engines have become the idiom today, this classification is based only on their rated speed, and I would like to elaborate here on the situation of high-speed diesel engines. However, it is said that medium-speed diesel engines and high-speed diesel engines are the same traction power as railroads. The quality of the same has also been confirmed, so there is no need to talk about their reliability and longevity. Taking into account the needs of the international locomotive market, locomotive traction as a medium-speed diesel engine or high-speed diesel engine can adapt
