1. Adopt original imported engine. It meets TIER 3 emission standards and features strong power, low noise, low fuel consumption and low emissions, and can meet the needs of various construction conditions. The high-pressure fuel injection system is adopted, and the fuel injection process is fully electronically controlled through the control of the fuel supply actuator and the timing actuator by the ECM.

2. The imported hydraulic components and the mature and reliable negative flow control system prolong the service life of the whole vehicle and improve the operation efficiency; the new main valve has a series of regeneration, confluence and priority functions to reduce energy consumption; hydraulic oil The heat dissipation adopts an independent heat dissipation system, which automatically controls the fan speed according to the oil temperature, which saves energy and reduces noise. At the same time, the fan has a reverse function, which is convenient for cleaning the dust on the radiator.

3. Set up a three-stage fuel filter system (one-stage coarse filter + two-stage fine filter) to effectively filter impurities in the oil to ensure long-term, high-load, continuous and reliable operation of the engine under harsh working conditions. The latest visual oil-water separator is adopted, and the replacement time of the filter element can be judged by the fuel level. The oil inlet resistance of the filter element remains unchanged throughout the use of the filter element, the cost of the filter element is lower, and the maintenance cost of the customer is reduced.

4. Adopt oil bath air filter + radial sealing air filter system, low maintenance cost, at the same time, the filtration efficiency reaches 99.99%, which can adapt to dusty and humid working conditions.

5. The electronic control system with excellent and reliable performance is adopted to realize the perfect match of power and hydraulic system, maximize the use of engine power, and ensure the fast and efficient operation of the machine.
