Product Introduction:
1. This engine is small in size and light in weight, so that it can be installed and used in a small space;
2. The tunnel structure is adopted, so that the reliability of the engine is guaranteed, and the noise is effectively controlled;
3. This engine has the characteristics of high torque and high torque reserve;
4. The PTO output torque is large, and the hydraulic pump works safely and reliably;
5. The layout of oil filter and diesel filter is reasonable, so it is easy to disassemble and maintain;
6. The unique oil consumption technology ensures that the oil consumption rate is lower than 0.15L/KW.h;
7. The international brand fuel pump is used together with low-friction technology to ensure lower fuel consumption and more
Good speed regulation; at the same time, the engine can be equipped with Weifu electronically controlled VP rotor pump, so that the speed regulation is within 1%;
8. The temperature of the engine inlet and outlet water is lower than 6 degrees, which ensures that customers have better terminal matching.
