Product advantages

Features

Emission: Euro Ⅴ Euro Ⅵ.

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

The movement speed of moving parts is reduced, and the movement time is prolonged.

The wear of friction pairs per unit time is reduced.

The service life of the crankshaft flywheel system and gear system is prolonged.

Economical

The maximum torque on external characteristic curve at low speed is improved.

The speed ratio of drivetrain is reduced, improving transmission efficiency.

The driver‘s shift schedule is improved, reducing fuel consumption.

The engine body saves energy by 5 %, and the vehicle saves energy by 10 %.

Comfortable

The high frequency torsional vibration zone of the engine is avoided.

The engine noise is reduced to 74 dB(A).
