1. Electronic control technology effectively solves the problems of engine running, loading and turning, white smoke, etc.; at the same time, the three-stage fuel filter is used to better protect the engine fuel system, and systematically improve the reliability and durability of the engine
2. The integrated design of “one piece with multiple functions” makes the number of parts and components less than about 25% less than that of the same type of engine, fewer connections, and higher engine reliability. The main bearing area is about 30% than that of the same type of engine, which can guarantee the engineering The machine still has a long working life under high-load working conditions.
3. Compared with the same type of engine, the torque reserve coefficient is larger and the power is stronger, which can meet various complex working conditions.
4. Turbocharger with wastegate valve, effectively improving engine power reserve and transient response.
