READ MOREUltra-Low Fuel Consumption
Optimized engine intake and fuel systems maximize engine potential, with special focus on reducing fuel consumption in the 60%–90% load range.
Cold Climate Adaptability
The engine can start directly at -15°C without auxiliary equipment.
At -30°C, it can start smoothly using intake preheating.
High-Altitude Adaptability
The engine delivers rated power at altitudes below 2000 m.
Above 2000 m, it continues to operate reliably.
Excellent Compatibility
Features a centrally mounted downward-facing turbocharger and a dedicated flat-bottom oil pan to reduce overall engine height.
Compact design makes it an ideal power solution for various generator set applications.
