The 17th China (Beijing) International Construction Machinery Exhibition (BICES 2025) grandly opened at the China International Exhibition Center! This year's exhibition has gathered over 1,400 domestic and international enterprises, jointly presenting the innovative achievements of the construction machinery industry as it ascends to new heights, advances towards intelligence, and progresses towards a greener future. Dongfeng Cummins participated in the exhibition with its market - proven and mature product, the B5.9 engine, showcasing its outstanding performance and reliable quality on - site!
The Core Advantages of Dongfeng Cummins B5.9: An Exemplification of Superior Performance
As an engine specifically designed for the construction machinery sector, the B5.9 not only boasts robust power, with a maximum power output of 240 horsepower, but also adopts the EGR technology route. This effectively reduces nitrogen oxide emissions without relying on a urea after - treatment system. As a result, it not only cuts down on operational costs but also simplifies the maintenance process, truly achieving free from worry and labor - saving.
Earning profits from energy saving
The fuel system upgrade enables a jet pressure of up to 2000 bar, which improves fuel atomization and ensures more complete combustion. The new turbine flow channel design and optimized blade processing profile, as well as the optimized turbine end Diffuser design, significantly enhance the efficiency of the turbocharger.
Capable of handling heavy-duty conditions with great power
Power range: 130-240 PS.
Maximum torque: 900 N·m.
Excellent low-speed torque performance. 710 N·m can be unleashed at 1000 rpm. Quick response, strong burst force, capable of handling various working conditions such as excavators, drilling machines, cranes, air compressors, road rollers, agricultural machinery, and sanitation equipment.
Intelligent control precisely regulates every drop of fuel.
Exclusive Leakless pressure retention technology makes superior starting performance. Closed-loop control system, real-time correction of fuel injection deviations, maintaining high precision fuel injection, continuously optimize fuel efficiency.
The preferred choice for green construction
The EGR technology route meets the latest emission standards, and the balance valve system enhances turbine efficiency without losing exhaust energy, helping achieve zero-carbon construction and jointly building a green future.
Economical and practical, with lower total life cycle cost.
Modular design reduces maintenance costs. Lightweight design makes installation more convenient. Under the same weight, it can provide stronger power for the equipment, and increase the operational efficiency of the equipment.
The flagship product has undergone market validation.
The Dongfeng Cummins B5.9 engine can be regarded as a star product. Since its launch, it has achieved a technological leap from mechanical to electronic control, and from the second generation to the fourth generation. It has accumulated over 20 years of technical accumulation and market validation. Not only has it continuously iterated and upgraded in technology, but it has also gained excellent reputations in terms of reliability, economy, and adaptability, becoming a trusted power choice for many original equipment manufacturers and end users.
