Recently, the relevant representatives of CRRC and Cummins China held a friendly discussion in Beijing, exchanged topics on the national dual-carbon strategy and the construction of a transportation power under the large-scale equipment renewal initiative of The State Council, improving the green transformation of rail transit equipment, and carried out constructive discussions on the further application of hydrogen energy in the field of locomotive cooperation.
Recently, the relevant representatives of CRRC and Cummins China held a friendly discussion in Beijing, exchanged topics on the national dual-carbon strategy and the construction of a transportation power under the large-scale equipment renewal initiative of The State Council, improving the green transformation of rail transit equipment, and carried out constructive discussions on the further application of hydrogen energy in the field of locomotive cooperation.
In response to the important measures of the state to promote large-scale equipment renewal to accelerate the construction of a new development pattern and promote high-quality development, CRRC continues to commit to technological innovation and product upgrading, and accelerate the new energy transformation of old railway internal combustion engines. Has deeply carried out the "diesel + power battery", "pure power battery", "hydrogen fuel cell + power battery" as the power source of the locomotive product development and new energy transformation supporting work, shoulder the national mission to accelerate the green and low-carbon transformation of railway equipment.
As a leader in power solutions, Cummins has provided the new generation QSK19/38 power package for CRRC's new energy shunting fleet. This series of engines has obtained EU IIIA emission certificates for internal combustion engines of the European Railway, and achieves better distribution of power and efficient use of energy through intelligent control systems.

In addition to more efficient in-cylinder combustion technology upgrades, the power pack's technology enhancements include:
Integral ball mill cast iron piston, cylinder durability increased by 10%-15%;
Modular high pressure common rail fuel system, accurately controlled electronic fuel injectors that can achieve multiple injection, the combustion process is smoother, idle stability is increased by 50%, cold start performance is increased by 50%, load response performance is increased by 18%, and noise is reduced by 80% compared with the previous generation fuel system engine;
Two-stage filter of nanomaterial fuel filtration system, to ensure reliable operation of the fuel system and 500 hours maintenance interval;
Advanced electronic monitoring and processing systems to further improve the efficiency of engine diagnosis.
This series of power packs has been gradually installed in the major locomotive lines of CRRC, truly realizing the efficient use of energy, ensuring that the locomotive can provide stable power output under various working conditions, while greatly reducing the emission of the locomotive and maintaining low noise operation.

This cooperation has brought good practice for the green transformation application of rail transit equipment in China and around the world, and has also laid a solid foundation for the in-depth cooperation between the two sides in the field of new energy.
During the talks, the two sides said that they will continue to increase investment in research and development, promote the application of more innovative technologies, including exploring the application of hydrogen locomotives, and work together to lead the development of rail transit equipment in a more green and sustainable direction, so as to create a green, intelligent and efficient rail transit future.
