How many cylinders, displacement and power does the domestic diesel locomotive engine have now?

At present, most domestic trains are Dali brand Dongfeng IV diesel locomotives made in Dalian, and Dongfeng XI diesel locomotives with about 5,500 horsepower are made by Changzhou Qishuyan Locomotive and Rolling Stock Factory, which is the most advanced at present, with 6,000 horsepower.

At present, the locomotives actually used in Chinese mainland are divided into diesel locomotives and electric locomotives. The displacement of electric locomotives is 0, and only diesel locomotives will have displacement. However, diesel locomotives generally do not indicate the displacement and number of cylinders, but indicate other technical parameters.

At present, there are many kinds of diesel locomotives actually used. Taking Dongfeng 8B as an example, we can see how the parameters of the train engine are marked.
