Cummins Features and Benefits
■ Crankshaft and Rod
Robust and fully balanced crankshaft design for a more steadily rotation and higher strength. Steel piston crown with oil gallery and aluminum skirts for better durability and low oil consumption.
■ 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.
■ Lubrication System
Dual spin-on filter can separate impurity above 10um effectively. Low pressure(220-310Kpa) and steady temperature(100-120°C)system can reduce auxiliary power wasting of the lubricating oil pump.
■ Cooling System
Great flux water pump and special 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.
