NEWS More options for MAN’ s 30-litre V12
MAN has adapted its big marine diesel engine so that it is suitable for an even wider range of applications
MAN’ s yacht engine is compact, for a 30-litre V12 that is n Despite an existing power range of over 1200hp from its twin-turbo 30-litre V12 diesel, the Bavarian commercial vehicle and engine manufacturer MAN, has added more variations of its D3872 engine portfolio. Initially launched in 2023 as a main propulsion maritime engine for workboats and yachts – the latter marketed as the V12X, and the version with the headline-grabbing 2200hp output – MAN has made the 30-litre V12 into a unit suitable for onboard generators for diesel-electric craft. Called the D3872 Auxiliary, it comes in with two possible power outputs – 1130hp and 1290hp. A static landbased generator version of the engine, the E3872, is also available with 986hp.
MAN has been able to adapt this engine to a variety of different applications because it not only complies with modern emissions regulations for sea and inland waterways – including IMO Tier II, III and EU Stage V – but it’ s also compact. For a 30-litre engine, that is. The D3872 is 1153mm wide and 1320mm high. That’ s no bigger than MAN’ s 24.4-litre V12; however, at 2335mm, it is 100mm longer than the smaller capacity motor. These small dimensions allow it to fit into confined engine rooms.
MAN’ s roots can be found in both Augsburg and Nuremberg in Bavaria, Germany. The two towns were made present in its name when the company was formed in 1898. It has been making commercial vehicles since 1915 and, in 1924, it presented the world’ s first direct injection diesel engine. It’ s now a part of the Traton Group – which is part of the Volkswagen Group – and continues to make commercial vehicles, along with buses and engines for the marine, agricultural and construction sectors.
