NEW: New launch of MAN Engines’ 9-litre off-road D1556 engine for construction machinery

The D1556 delivers between 205 and 324 kW (297 and 440 PS). It’s broad power plateau is attributed to the turbo charger with its variable turbine geometry (VTG) , as well as the common-rail system which ensures injection pressures of up to 2,500 bar.

Based on these technologies, the power unit develops its power uniformly and dynamically, even at the lower end of its speed range. With a dry weight of just 860 kg, it is the lightest off-road engine in its displacement class. “With the D1556, the MAN Engines engineers have succeeded in developing an engine with a high power-to-weight ratio and compactness that is perfectly suited to the requirements of off-road applications. In addition, as the first 9-litre engine from MAN Engines, it completes our engine portfolio for construction machinery and closes the gap in our range between the well-established MAN D0836 range with 6.9-litre displacement and the D2676 with 12.4-litre displacement,” explains Hubert Gossner, head of off-road sales at MAN Engines. Thanks to the equally space-saving MAN Engines exhaust gas aftertreatment (AGN) system, the engine meets current emission standards such as EU Stage V and US Tier 4. The exhaust gas aftertreatment system consists of the two DOC/DPF modules (diesel oxidation catalytic converter/diesel particulate filter), as well as an SCR (selective catalytic reduction) system with a special mixer.
