Cummins 6LTAA8.9 advantage of the engine, and the engine model, rated power, maximum torque and other specifications.
1. Long stroke
Expansion of the combustion gases more fully, to increase the effective power output, ensuring low fuel consumption under strong driving force.
2. The advanced 4-valve structure
More horsepower, more thorough air combustion, low fuel consumption, while allowing low-speed torque increase, power, and high efficiency.
3. Articulated piston with forced cooling
Can withstand high mechanical and thermal loads, good strength.
4. Enhanced cylinder design
Low noise, small vibration.
5. Center injectors and symmetrical arrangement of the combustion chamber
Makes the mixture more uniform cylinder, burning more fully.
6. The advanced design
L Power 30.0kW / L, a reasonable ratio up to the machine structure, maintenance more convenient.
