Cummins L8.9 Diesel Engine

Product Advantages

• Higher working efficiency: A longer stroke ensures more full combustion gas expansion, higher effective power output and lower fuel consumption under strong power; and the advanced 4-valve structure brings about higher horsepower, more thorough air combustion, and increased low-speed torque output, thereby improving the working efficiency. • Leading manufacturing process: The forced-cooling articulated piston can withstand extremely high mechanical load and thermal load, and ensures a strength comparable to that of heavy-duty engines; the strengthened cylinder design greatly reduces the noise and vibration. • Strong power: The air-to-air cooling and turbocharging technology ensures a better engine power performance. • Lower emission: The center-arranged injector and symmetrical combustion chamber make the air-fuel mixture in the cylinder more uniform, the combustion fuller and the emission lower. • Higher fuel economy: The fuel economy is higher, the service life is longer, and the durability and reliability are much higher than similar engines in China.

Cummins L8.9 Engine – Overview & FAQ

Part of Cummins' L8.9 platform (badged 6LTAA8.9 for industrial/marine use), based on a stroked version of the 8.3L C-series block rather than the original 1982 L10, and built by Dongfeng Cummins (DCEC) for construction machinery, marine propulsion and heavy Dongfeng trucks. This truck/bus variant delivers 375hp (280kW) with 1480N.m of torque, part of the earlier Landking-era L8.9 truck engine lineup for heavy Dongfeng vehicles.
