Under the scorching sun of the third month of summer, the road surface is extremely hot. For intercity delivery and cold chain refrigeration transportation, high temperatures are not only a physical challenge but also a limiting squeeze on the vehicle's power chain.
Engine overheating leads to torque limitation? Fuel consumption soars and costs get out of control? Reduced cooling effect? In the summer of 2026, the Dongfeng Cummins D2.5 / D3.0 engine, with its cutting-edge power technology, is stepping up the battle with a strong presence, using its strength to define what it means to be the king under high temperatures!
Resistant to high temperatures, with superior temperature control, unafraid of scorching heat.
Dongfeng Cummins D2.5 & D3.0 are not merely a simple technological upgrade; they are an efficient power platform developed based on the "Adapt to Market Demand 2.0" development strategy, fully meeting the requirements of National VI B and the four-stage fuel consumption regulations.
With modular design, the structure is more reasonable, the failure rate is lower, and the reliability doubles under high-temperature conditions.
The intelligent thermal management system is like equipping the engine with a "variable-frequency air conditioner", capable of actively regulating heat and the cooling rhythm. Under continuous heavy-load operation, it achieves precise temperature control, eliminating the anxiety of "boiling over".
The efficient after-treatment system has its structure fully optimized and highly integrated, operating efficiently. It not only fully meets the fuel four-stage emission standards in one step, but also ensures that every drop of fuel burns more fully under high temperatures.
Light and reliable, power online, full of explosive force.
Say goodbye to the helplessness of a small vehicle pulling a large load. Dongfeng Cummins D2.5 & D3.0 give you confidence anytime and anywhere.
Dongfeng Cummins D2.5 Engine - City Delivery War Hero, Efficient and Powerful.
With a maximum horsepower of 185 and peak torque of 550 N·m, it is suitable for light trucks ranging from 4.5 to 7.5 tons, fully meeting the transportation needs of frequent short trips in urban areas.
Dongfeng Cummins D3.0 Engine - Cold Chain Power, Secure Freshness.
With a maximum horsepower of 210 and peak torque of 650 N·m, it is specially designed for 7.5-ton to 12-ton light trucks and fully compatible with various scenarios such as cold chain delivery and general cargo transportation.
Dongfeng Cummins D2.5 / D3.0 - Low-speed torque increased by 18%.
Even in high-temperature conditions, heavy-load starting and uphill overtaking remain as powerful as ever. Even in refrigerated and low-temperature transportation scenarios, the D3.0 engine can still maintain sufficient power, ensuring both cooling and acceleration, fully guaranteeing the integrity of the fresh food cold chain.
