1. Use the original imported engine. It meets the TIER 3 emission standard, has the characteristics of strong power, low noise, low fuel consumption and low emission, and can meet the needs of various construction conditions. The high-pressure fuel injection system is adopted, and the full electronic control of the fuel injection process is realized through the control of the fuel supply actuator and timing actuator by the ECM, and the fuel injection quantity and injection time are precisely controlled to reduce fuel consumption and improve engine efficiency.
2. Originally imported hydraulic components and a mature and reliable negative flow control system prolong the service life of the vehicle and improve operating efficiency; a series of regeneration, confluence and priority functions of the new main valve reduce energy consumption requirements; hydraulic oil The heat dissipation adopts an independent heat dissipation system, and the fan speed is automatically controlled according to the oil temperature to save energy and reduce noise. At the same time, the fan has a reverse function, which is convenient for cleaning the dust on the radiator.
3. A three-stage fuel filter system (one-stage coarse filter + two-stage fine filter) is installed to effectively filter impurities in the oil to ensure long-term, high-load, continuous and reliable operation of the engine under harsh conditions. Using the latest visual oil-water separator, the replacement time of the filter element can be judged by the fuel level. The oil inlet resistance of the filter element remains unchanged during the whole process of using the filter element, and the cost of the filter element is lower, reducing the maintenance cost of customers.
4. It adopts oil bath air filter + radial seal air filter system, which has low maintenance cost, and the filtration efficiency reaches 99.99%, which can adapt to dusty and humid working conditions.
5. The electric control system with excellent and reliable performance is adopted to realize the perfect match between the power and the hydraulic system, maximize the use of engine power, and ensure the fast and efficient operation of the machine.
