Groundbreaking in the 9-litre class: The MAN D1556 diesel engine for off-road applications. This straight-six power unit delivers between 205 and 324 kW (279 and 440 HP). Its highest power variant achieves a maximum torque of 1,970 Nm at speeds between 1,150 and 1,300 rpm. Even at low speeds, the MAN D1556 delivers high torque. And 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 high power density and compactness that is perfectly suited to off-road application requirements. In addition, as the first 9-litre engine developed by MAN Engines, it completes our engine portfolio for construction and agricultural machinery and bridges the gap in performance between the well-established MAN D0836 series with 6.9-litre displacement and the D2676 with 12.4-litre displacement,” explains Hubert Gossner, head of off-road sales at MAN Engines. Individual solutions MAN Engines offers the most individual solutions for engine integration into the machine in order to perfectly adapt the engine characteristics to application and load profiles and thus ultimately to differentiate it from the competition among machine manufacturers. Solutions can be of a mechanical nature such as weight-saving plastic oil pans or oil pans with load-bearing structure, electronic adaptations via the engine control (EDC), or features that are even reflected in the machine concept such as electronic immobilisers.
