MAN engines for agricultural and construction machinery
The MAN D2862 LE13x has a power range of 588 to 816 kW (800 to 1,110 HP), available in power ratings of 588, 650, 750 and 816 kW (800, 884, 1,020 and 1,110 HP). With a cylinder bore of 128 mm and a stroke of 157 mm, the MAN 12-cylinder engine offers a displacement of 24.24 litres. As a result, the unit generates a remarkable maximum torque of 3,750 to 5,000 Nm between 1,300 and 1,400 rpm using wastegate turbocharging, for example for installation in forage harvesters and heavy construction machinery.
Compact installation dimensions of 1,660 x 1,333 x 1,391 mm (L x W x H) and a modular exhaust gas aftertreatment system with freely positionable single components offer machine manufacturers the highest level of flexibility when designing system installations. To comply with Tier 4 final and EU Stage V emission standards, the MAN D2862 LE13x uses “SCR only” technology (selective catalytic reduction) without exhaust gas recirculation.
MAN has over 40 years experience as an engine supplier for agricultural machine manufacturers, a fact which comes to bear in the engines that MAN specially develops for agricultural machinery. In addition to designing particularly robust components, such as auxiliary units or belt drives, the engines are also well-equipped to be used in dusty, hot conditions thanks to insulation measures on the exhaust system. For maximum oblique positions, MAN engineers create special oil pans and design the power supply based on a 12 V vehicle electrical system commonly used in agricultural equipment, in addition to also offering a 24 V standard variant. Even the integration of engines into specific installation spaces and vehicle concepts is part of the MAN Engines service portfolio. “It was back in the early 80s that we first installed our highly robust load-bearing structure consisting of the oil pan, crankcase and flywheel housing. Together they became the load-bearing parts in agricultural tractor construction and thus helped create a particularly small turning circle and low vehicle weight,” explains Hubert Gossner, Head of Off-Road at MAN Engines, with pride.
