1. The king of cost-effective power

2.Ultra low fuel consumption

Optimize the engine intake and fuel system, explore the engine potential, focus on optimizing the fuel consumption in the range of 60% ~ 90% load rate, and reduce the fuel consumption.

3.Strong adaptability

Cold adaptability: when the temperature is - 15 ℃, the engine starts directly without auxiliary measures; When the temperature is 40 ℃, the engine can start smoothly by preheating the intake air.

Plateau Adaptability: when the altitude is less than 3000m, the engine can output rated power; When the altitude is greater than 3000m, the engine can work reliably.

4.Good adaptability

The center mounted down turn turbocharger and special flat bottom oil pan are adopted to reduce the height of the whole machine; Compact structure, it is the ideal power of silent diesel genset.
