MAN Engines presents unique range of engines for construction machinery

Successful agricultural engine business provides solid foundation; new D4276 and D1556 engine series at Bauma trade fair; future engine developments can draw on commercial vehicle business.

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. “Engines for construction machinery are an important part of our long-established off-road business, which has deep roots at MAN Engines. At the same time, we have invested many millions of euros in new and existing products in recent years,” says Reiner Rößner, head of sales at MAN Engines. 

Thanks to consistent upgrades and progressive development, MAN Engines has been able to develop a complete selection of off-road products ranging from 4.6 L to 24.2 L displacement, based on the latest engine platforms and the newest technology. The current highlights are the world première of the D4276 and the newly launched D1556 for construction machinery, both making an appearance at this year’s Bauma trade fair. In terms of power, this will give original equipment manufacturers a range of seven engine series to choose from, spanning 118 kW to 816 kW (158 hp to 1,095 hp). Early projects and collaborations confirm that the engines are also in demand and enjoying success in construction machinery. 

Commercial vehicle business helps ensure long-term partnership 

As a business unit of MAN Truck & Bus – and, in turn, a part of the Traton Group – MAN Engines benefits hugely from a wealth of experience in mass production of commercial vehicle engines. After all, the key to developing engines with a high degree of quality and efficiency for large construction and agricultural machinery is to utilise the essential technology used in engines on the construction site and for long-haul transport. This requires use of the latest technology and meticulously developed components. “Our high-volume commercial vehicle business will be the only way in the medium term to safely meet increasing technology requirements and ensure modern engine series that are fit for the future. That way, we can give our customers long-term reliability of supply when it comes to the latest diesel technology,” Rößner explains. 

Highly specialised, easy to integrate MAN Engines’ off-road customers can benefit from the ability to easily integrate the engines in their system environment. As an engineering service provider for OEMs, MAN Engines relies on tailor-made solutions that meet automotive industry standards. In addition, it can already offer the necessary interfaces for engines to benefit from the ever-growing digital transformation and networking of components. The engine dynamics are specially adapted to suit the application at hand thanks to wastegate charging or exhaust turbo chargers with variable turbine geometry. This allows MAN engines to ensure sufficient charging pressure and dynamics for construction machinery, mining vehicles, rock crushers, environmental applications and shredding tasks – even at the low revolution and efficient engine speed range. 

Modular exhaust gas aftertreatment for EPA Tier 4 Final and EU Stage V

The availability of emission standards ranging from US Tier 4 Final to EU Stage V ensures that high-volume manufacturers and niche solution providers alike can sell their machines around the world. MAN Engines’ compliance with current and future emission standards is due to its many years of experience with exhaust gas aftertreatment systems in the Group’s own commercial vehicles and large-scale production of industrial engines. Thanks to the modular exhaust gas aftertreatment (AGN) system used and the ability to freely choose component positioning in all MAN engines, flexible system integration is possible with a high degree of packing density. Sixteen different AGN variants enable machine manufacturers to make ideal use of the space in an item of equipment.

As well as coming in useful for applications where space is essential, this also boosts compatibility and flexibility during engine installation. And there is no need to include the AGN and/or the diesel particulate filter for exhaust emission standards that differ on a regional and national level. This flexible system enables manufacturers of off-road machinery to offer their products around the world without having to change the installation conditions for their basic engines.
