铁路提速的最快战略措施是利用现有的成熟内燃机车和柴油机系列产品，提高其可靠性并利用技术储备进一步开发孪生产品和进一步提高功率，以求大部分零部件通用互换，以利生产、运用维修和机车的不断更新换代，延长使用寿命。本文将240系列柴油机与国外最新大功率内燃机车的柴油机的强化指标作了比较，从而说明其设计上的可靠性可与国外产品相媲美，可以负担铁路提速的任务，并有进一步开发孪生产品的潜力。 The quickest strategic measure for speeding up of railways is to utilize existing mature diesel locomotives and diesel engine products to enhance their reliability and utilize the technology reserve to further develop twin products and further increase power so that most of the components can be interchangeably exchanged for the benefit of production , The use of maintenance and locomotives constantly updated to extend the service life. In this paper, the 240 series diesel engine with the latest high-power diesel locomotive diesel engine intensification indicators were compared to demonstrate the reliability of its design can be comparable with foreign products, you can afford the task of railway speed, and to further develop the twin products potential.
