MAN Engines unveils E3872 gas engine
The new MAN E3872 gas engine offers 44% efficiency and 735 kW power output from just 12 cylinders. Design modifications have made it possible to significantly increase the mechanical efficiency.
MAN Engines showcases its new MAN E3872 series for the first time at the Biogas Convention & Trade Fair. It is designed as a four-stroke spark-ignition gas engine with a displacement of 29.6 litres, a bore of 138 mm and a stroke of 165 mm. With the 735 kW it produces, MAN Engines is now able to supply gas engines with a significantly higher power output. At the same time, the engine manufacturer from Nuremberg, Germany, is remaining true to its philosophy of achieving high power density. Thus, the new MAN E3872 series is based on the proven and compact platform of the 25.8-litre MAN E3262. “MAN Engines is synonymous with robust engines that take up very little space. The impressive output is a customer-oriented solution with undeniable added value in terms of serviceability, maintenance and operation costs,” says Reiner Roessner, Head of Sales at MAN Engines.
MAN Engines: efficiency increased
The basis for this engine is the existing crankcase of the MAN E3262, which has been in use since 2010. Steps were taken to increase bore and stroke and the robustness of the crankcase as well. Other changes were made to the turbo charger concept, the combustion process and the cylinder heads. The result is an efficiency rate increased to 44% which makes the engine particularly suitable for applications where the focus is on the production of electricity and additional generation of heat. This opens up a wide range of potential applications in the agricultural and municipal sectors, in hotels, hospitals and industrial plants.
As part of the process of converting the stationary natural gas engine portfolio to a state of “hydrogen readiness”, the new E3872 engine will also be designed to run with hydrogen admixture (H2) if operated with natural gas.
