Product advantages

Emission: Euro V.

Power performance: High power, high torque (and high output torque at low speed).

Economy: The optimized powertrain system ensures low fuel consumption; the engine is able to achieve high mechanical efficiency at low speed, ensuring low fuel consumption.

Comfort: The customized development of NVH ensures low noise and vibration.

Reliable

B10 life is greater than 1,000,000 km.

Better economy

The speed that can achieve minimum fuel consumption covers the whole working speed range.

The intake and exhaust manifolds are arranged on different sides, improving charge efficiency, optimizing combustion, and improving economy.

Comfortable

The integrated rotor-type oil pump and standard shear gear reduce the transmission noise further.

The engine noise is reduced to 79 dB(A) @ idle ，93 dB(A) @ rated power.
