MAN Engines presents unique range of engines for construction machinery
MAN Engines is the leading manufacturer of diesel engines for off-road applications. With many years of product experience at its disposal and a unique range of engines on offer, the engine manufacturing firm is now even better-equipped to provide solutions for excavators, wheel loaders, dumper trucks and mobile cranes. With the new engine series D4276 and D1556.
World première: 16.2-litre D4276 engine from MAN Engines for construction machinery sets new benchmark
At Bauma, MAN Engines will be debuting its new straight-six engine, the D4276, with 142 mm bore and 170 mm stroke. This power unit has been developed specially for applications that demand high power with full power operation at up to 70 percent of the duty cycle. It delivers its maximum torque of 3,280 Nm at speeds as low as 1,100 rpm and maintains a constant torque up to 1,500 rpm. The straight-six engine offers not only high torque but also an impressively high power-to-weight ratio. With a dry weight of just 1,280 kilograms, it is one of the lightest engines in its displacement class, and delivers an output between 450 and 515 kW (604 and 690 hp) depending on its power stage. Its design is based on the D3876 engine range, which has been a well-established success on the market since 2014.
At the Bauma trade fair’s media days, MAN Engines will be exhibiting the 9-litre-displacement D1556 diesel engine for construction machinery. This straight-six power unit delivers between 205 and 324 kW (275 and 434 hp). Its highest power variant achieves a maximum torque of 1,970 Nm at speeds between 1,150 rpm 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.
All units are designed for the currently valid US Tier 4 final/CARB and EU stage IV emission standards. With the use of modular exhaust gas aftertreatment, the entire engine range is optimally equipped for the future EU stage V without intervention in the basic engine.
