The D2676 LE13x in-line six-cylinder engine made by MAN is the new benchmark for powering forage harvesters, combine harvesters and tractors. High flexibility in the widest range of applications as well as appreciably high efficiency convince machinery manufacturers and end users of the quality of the compact power pack. The D2676 LE13x satisfies strict exhaust-gas standards EC Step IV and US EPA Tier 4 final/CARB and saves weight in the process, as it manages without additional components such as a diesel oxidizing catalyst or a diesel particulate filter.
The MAN D2676 LE13x echoes the rating range from 294 to 382 kW (400 to 520 HP) at 1,950 rpm occupied by its proven predecessor. The efficient power pack is available in four ratings: 294 kW, 324 kW, 353 kW, 382 kW (400 HP, 440 HP, 480 HP, 520 HP).
With its cylinder bore of 126 mm and a stroke of 166 mm, the D2676 LE13x develops its maximum torque of 1,875 to 2,400 Nm from a cubic capacity of 12.4 liters. The D2676 LE13x satisfies strict exhaust-gas standards EC Stage IV and US EPA Tier 4 final/CARB and saves weight in the process, as it manages without additional components such as a diesel oxidizing catalyst or a diesel particulate filter. Downgraded variants for countries with less strict exhaust-gas regulations will also be available.
A miracle of space: Flexibility thanks to modular exhaust-gas aftertreatment
In the modular exhaust-gas aftertreatment system, extremely different installation variants can be devised thanks to variable positioning of individual components of the SCR catalyst. This kind of module kit makes for flexibility throughout the range. Beside this, the engine's compact dimensions of 1,376 x 925 x 1,288 mm (length x width x height) allow engineers maximum freedom for designing the perfect powertrain for a particular vehicle. Airless dosing of the urea solution for SCR yields further space-related advantages. "With the D2676 LE13x we have created an extremely efficient and flexible engine with benefits for vehicle manufacturers, machinery operators, and drivers alike", said Jürgen Haberland, Head of Off-Road MAN Engines.
Power source: Efficient thanks to variable turbine geometry
As a long-standing expert in the off-road sector, MAN has unveiled in the D2676 LE13x an engine that has been specifically developed and optimized for the requirements of agricultural machinery. Based as it is on the large-scale series production technology of the MAN vehicle engines, this unit comes with impressively long service intervals and low maintenance input. The variable turbine geometry opens up freedom to adjust torque curves perfectly to specific applications:
Haberland is convinced: "We can configure the engine characteristics individually and optimally to any application and thus get the maximum efficiency for the user out of the engine". Targeted use of this efficient technology gives the D2676 LE13x attractive features such dynamic response, high torque in the low speed range, and an improved torque curve. The outcome of this combination of variable turbine geometry and the experience of MAN's engineers is reduced fuel consumption coupled with lower noise emissions than the predecessor model.
