On January 8, 2025, at the "19th Great Influence to Bus Industry, Forum on the Innovative Development of New Productive Forces, and Bus and Coach Technology Exchange", Dongfeng Cummins D6.7 Euro VI series engines, with their outstanding overseas product performance and user reputation, successfully won the "International Marketing Collaboration Award" for the 2024-2025 period in the bus industry. Dongfeng Cummins has won this honor for consecutive years thanks to its excellent product strength.

Leader in Transport Power, Winning Recognition from Overseas Customers

The technical level of engines directly affects vehicle performance and operational efficiency. The D-series engines, developed through the cooperation between Cummins and Dongfeng and rooted in China for many years, have won good user reputation from the Euro III, IV, V, to VI standards. Tailored to the needs of China's bus exports and overseas markets, the Dongfeng Cummins D6.7 Euro VI series products have undergone comprehensive upgrades in fuel economy, reliability, and power performance, bringing greater economic benefits and more comprehensive, reasonable power service solutions to customers.

The Dongfeng Cummins D6.7 Euro VI series engines have a maximum power of 320 horsepower and a maximum torque of 1,200 N·m, with significant torque improvement and enhanced climbing ability. In terms of intelligence, the Dongfeng Cummins D6.7 Euro VI series engines are empowered by smart technology to achieve convenient interaction among "people, vehicles, and machines". Relying on the Cummins smart system, these products utilize intelligent technologies such as smart coasting, and comprehensive information management of vehicle real-time status to optimize speed and shifting strategies, providing customers with the best balance between power and economy.

Furthermore, the 1,800-bar high-pressure common rail system improves combustion efficiency and further enhances fuel economy. The SS start-stop technology allows the engine to shut down during idling, significantly saving idling fuel consumption. The lightweight design, with some parts made of high-strength composite materials, reduces the engine's weight and improves operational efficiency. The smart fuel consumption management system comprehensively considers vehicle driving demands, weight, and road conditions to provide the most optimized fuel consumption management solution.

In terms of durability, the 6.7-liter platform has sold over one million units globally, inheriting the high reliability of the ISD6.7 from the Euro V stage. The optimized piston ring structure and coating materials reduce frictional power consumption, enhance part wear resistance, and extend part service life. The adoption of Cummins' patented Inter-brake in-cylinder braking technology ensures safety, reliability, and economy.

Dongfeng Cummins has maintained close cooperative relationships with domestic first-class vehicle manufacturers and has become an important partner for bus companies in their international market expansion. Winning the "Bus International Marketing Collaboration Award" again this time reflects the recognition and affirmation of Dongfeng Cummins' achievements by overseas users and the market, and is the best footnote to Dongfeng Cummins' bus engine business performance in 2024.

Both the Dongfeng Cummins B6.2 Pro and D6.7 have won significant industry awards, further confirming Dongfeng Cummins' strong product strength. In the future, Dongfeng Cummins will continue to pursue technological innovation, be market-oriented, fully transition towards digitization and intelligence, enrich its product line and improve its product matrix, and provide customers with more efficient, economical, and reliable green products to reciprocate the trust and support of the industry and users!
