■ Cylinder Block
High quality alloy cast iron for the rigidity performance and lower vibration and noise. Wet and replaceable cylinder liners for better heat rejection performance and easier replacement.
■ Head and Valve
4 valves per cylinder, Optimize the mixed level which lead to an excellent fuel consumption rate and emission performance. High quality alloy cast iron, one cylinder on head, single camshaft and special designed outline for better reliability and durability.
■ Fuel System
Cummins unique PT with fixture and Step Timing control for precise fuel injection make the fuel injection pressure above 120Mpa, which leads to an excellent fuel consumption rate and emission performance. Check valve in fuel tube improve reliability.
■ Cooling System
Great water pump and great flux channel design provide effective cooling. Spin-in water filter makes the coolant clean and keeps it in normal acidity.
■ Exhaust System (After-cooled)
Advanced Holset turbocharger and water-air after cooler technology, pulse exhaust manifold reduce exhaust temperature, provide excellence fuel consumption and emission performance.
