Development of the 9 litre engine MAN D1556 for agricultural applications
In 2019, MAN launched a newly developed engine with a displacement of 9 liters. In addition to traditional applications for trucks and coaches, the industrial version has been presented at the same time. For its first application in the off-highway segment, the engine is used in agricultural tractors, where SCR-only combustion and exhaust gas aftertreatment have been completely revised and adapted. Read here a technical article about the development and validation of the MAN D1556 for Off-Road applications.
The MAN D3876 was presented as a completely new and standalone engine series from MAN in 2014. This 15.26 l in-line 6-cylinder engine has replaced the previous MAN D2868 16.2 l V8 engine in the commercial vehicles sector and will also gradually replace the V8 engine in off-road applications with the introduction of the new emission categories.
To create an engine with a minimum 500 hp for use in a powerful standard tractor without articulated steering that complies with Tier 4 final and EU Stage IV exhaust emissions standards, the engineers at MAN based their designs on the D2676 power train for trucks, adapting this to meet the requirements of a tractor.
The new D2676 marine engine developed by MAN is based on the D26 engine, which has proven its worth in heavy-duty vehicles, and provides an optimal, compact, low-consumption engine with a low performance weight for use in boats.
In the D2862/68 V-engine series developed by MAN, 8- and 12-cylinder engines have successfully been brought to market in road vehicles, agricultural machinery, trains, yachts and working vessels as well as for power generation in the form of diesel- and gas-powered units.
thanks to the compact installation dimensions and low weight of the vertical MAN engine, the complete drive package comprising diesel engine and generator, air filter, cooling, exhaust, electrical and electronic systems can be arranged on the roof of the vehicle.
The innovative power units were first installed in its own farming machines, ranging from motorised plough to tractors, but were later mostly sold to other manufacturers. Nowadays, MAN engines are being used where highest standards of performance and efficiency are required. They are present in a broad range of agricultural equipment from numerous manufacturers.
