Features

Emission standards: Euro V and Euro VI.
Technical route: The electronically controlled high-pressure common rail system is used to ensure precise control.
Comfort: The customized development of NVH ensures low noise and vibration.
Light weight: Its applies a large number of cast aluminum parts and is the lightest one among those products of same power.
Small size: small in size, ensuring the easy assembling in OEM.

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.

Better economy

More comfortable

The high frequency torsional vibration zone of the engine is avoided.
The noise reduction flywheel housing and the domestic advanced anechoic chamber are used to reduce noise.
