This paper discusses a reconstruction program to achieve low constant speed control function on existing DF8B diesel locomotives and how to design and implement the low constant control algorithm using PI regulator.

The reason of break in the high pressure fuel pipe purchaced from outside for 280 diesel engine of DF8B locomotive is analised.

By studying the domestic DF8B locomotive and employing explicit finite element software ANSYS/LS-DYNA, this paper founds a simulation model in which the DF8B locomotive makes a frontal concision on rigid wall at a speed of 10 m/s.

The main reasons of leakge from water pump for DF8B locomotive were analyzed.

The reasons for DF_(8B) locomotive water leakage are analysed and the countermeasures are proposed.

Test and running assessment of the radial bogie of DF_(8B) locomotive;

Pollutional control of fuel systems for diesel locomotives;

Development of diesel locomotive in new century and its new strategy;

Suppression of inductive load over-voltage for diesel locomotive circuit;

The fifth generation diesel engine oil containing zinc for railway internal combustion locomotive was prepared from paraffinic base oil with high quality cleaning dispersant and anti-oxidation additive package, etc.

This paper introduces the parameters of the technical performances, the structural features, the performances of the main parts, the calculation of the tractive characteristics, and the characteristic curves of TY360 type internal combustion locomotive.

An innovative prototype of exhausted heat powered solid adsorption air conditioning system with zeolite water pair used for internal combustion locomotive cab was presented and analyzed.
