China Cummins -B125 Truck diesel engine | Tonkee®

The B125 engine is built on Cummins' legendary B-Series platform, known for its robustness and longevity.

It utilizes a 4-stroke, inline 6-cylinder configuration that ensures smooth operation and efficient power delivery. The engine is turbocharged, allowing it to produce high levels of torque across a wide range of engine speeds.

One of the standout features of the B125 engine is its power output. It delivers an impressive 400 horsepower, making it suitable for demanding applications such as long-haul transportation, construction, and heavy equipment. The engine's torque rating is equally impressive, generating up to 1,250 lb-ft (1,695 Nm) of torque, providing excellent pulling power and acceleration.

The B125 engine incorporates advanced fuel system technology to optimize combustion and enhance fuel efficiency. It utilizes a high-pressure common rail fuel injection system, which delivers precise amounts of fuel directly into the combustion chamber. This system improves fuel atomization, resulting in better combustion efficiency and reduced emissions. Additionally, the engine features an integrated exhaust brake, which helps improve vehicle control and reduces brake wear, especially during downhill descents.

To ensure durability and longevity, the B125 engine is built with high-quality materials and robust components.

It features a cast-iron engine block, which provides excellent strength and rigidity. The engine also incorporates a robust overhead camshaft design, roller lifters, and a forged steel crankshaft, all contributing to its durability and reliability.

The B125 engine is compliant with the latest emissions standards, including EPA and CARB regulations. It incorporates Cummins' advanced aftertreatment system, which includes a diesel particulate filter (DPF) and selective catalytic reduction (SCR) technology. This system helps to minimize harmful exhaust emissions, making the engine environmentally friendly while maintaining optimal performance.
