Advanced Hydraulic System
Proven negative flow hydraulics have optimize the main control valve, improved the speed of front end cylinders, while cutting down the hydraulic system’s damper loss, leading to much better
working efficiency. The pilot valves matching with the main control valve offer precise control.

Engine
Equipped with a fuel efficient world-class Cummins engine meets stage IV/EPA Tier 4 final emission standards. The engine come with a combination of a cooled-EGR system. It is also complemented
by the Cummins patented VGTTM Turbocharger, which continuously varies the airflow boost to precisely match engine and load demand for optimal performance.

6 Working Modes
Power, Economy, Fine, Lifting, Breaker, Attachment.
The LiuGong E series excavator features 6 selectable working modes that optimize performance and fuel consumption to your specific conditions.

Intelligent power control
The advanced IPC (Intelligent Power Control) system makes full use of engine oil consumption characteristics, matching the engine-hydraulic pump to achieve high efficiency, low and economical fuel consumption.

Auto-Idle Speed Function
Automatic speed reduction in neutral can reduce fuel consumption and noise. Automatic velocity control is divided into two levels: if in 1second, no hydraulic request signal is detected, the engine speed will automatically reduce by 100 RPM; If after 3 seconds no hydraulic signal is detected, the engine speed will drop to idle speed. When the system detects the hydraulic signal, the engine will immediately return to the current throttle setting speed.
