Recently，Representatives of CRRC and Cummins China hold friendly talks in Beijing，JustThe construction of transportation power under the national double-carbon strategy and the State Council's promotion of large-scale equipment renewal、Improving the Green Transformation of Rail Transit EquipmentTopic communication，The further application and cooperation of hydrogen energy in the field of locomotives are discussed constructively.。

 

In response to the statePromoting large-scale equipment renewal to speed up the construction of a new development pattern、Promoting high-quality developmentAn important move，CRRC remains committed to technological innovation and product upgrading，Accelerating the New Energy Transformation of Old Railway Diesel Locomotive，It has been carried out in depth“Diesel engine+Power Battery”、 “Pure power battery”、“Hydrogen fuel cell+Power Battery”Locomotive product development for power source and supporting work for new energy transformation，Shoulder the National Mission and Accelerate the Green and Low Carbon Transformation of Railway Equipment。

 

As a leader in power solutions，Cummins provides CRRC's new energy shunting locomotives withA new generationQSK19/38 Power pack。This series of engines has been obtained by the European Union railway diesel locomotives.EU IIIAEmission certificate，Better distribution of power and efficient use of energy through intelligent control systems。

In addition to more efficient in-cylinder combustion technology upgrades，The technical improvement of the power pack product also includes：

✓

Integral ball milling cast iron piston，10% improvement in cylinder durability%-15%；

✓

Modular high pressure common rail fuel system、Precisely-controlled electronic fuel injector capable of realizing multiple injection，Smoother combustion proces，Increased idle stability by 50 percent% ，50% improvement in cold start performance%，Increased load response by 18 percent%，Noise is reduced by 80% compared to previous generation fuel system engine%；

✓

Fuel oil filtering system of nanomaterial with two-stage filtering，To ensure the reliable operation of the fuel system andMaintenance interval of 500 hours；

✓

Advanced Rich Electronic Monitoring and Processing System，Further improve the efficiency of engine diagnosis。

 

This series of power packs have been gradually installed in the major shunting locomotive lines of CRRC.，Really realize the efficient use of energy，To ensure that the locomotive can provide stable power output under various working conditions.，Ignificantly reduce locomotive emissions and maintain low noise operation。
