DCEC 6L8.9 Construction Machinery Engines Detailed information

Higher Work Efficiency:
Longer stroke allows for more complete expansion of combustion gases, increasing effective power output and ensuring low fuel consumption under strong power.
Advanced 4-valve structure provides greater horsepower, more thorough air combustion, and increased low-speed torque, enhancing overall work efficiency.
Leading Manufacturing Process:
Forced-cooled articulated pistons can withstand extremely high mechanical and thermal loads, with strength comparable to heavy-duty engines.
Enhanced cylinder block design significantly reduces noise and vibration.
Strong Power:
The use of air-to-air intercooling and turbocharging technologies improves engine performance.
Lower Emissions:
Centrally located fuel injectors and symmetrical combustion chambers ensure more uniform mixture in the cylinder, leading to more complete combustion and lower emissions.
Higher Fuel Economy:
Excellent fuel economy, long service life, and significantly higher durability and reliability compared to domestic engines of the same class.
