Automatic idle speed, the engine will automatically adjust to automatic idle speed if the whole machine has no action for more than 10 seconds, further reducing fuel consumption.
The engine adopts electronically controlled high-pressure common rail technology, multiple injections can be precisely controlled and fuel economy improved by 15%.
Enlarge the internal passage of the main valve, thicken the pipeline diameter, optimize the pipeline direction, reduce the
hydraulic loss along the way, and reduce the hydraulic system energy loss by 5%.
New 5.7-inch flat-panel ultra-thin LCD instrument information review is clearer.
By optimizing and improving noise and vibration sources, noise is reduced and driving comfort is improved.
The engine core parts are guaranteed for up to 5 years/10000 hours, which is safe and worry-free.
