Consortium to Develop Medium Speed Ammonia Fuelled Engine

MAN Energy Solutions has begun the ‘AmmoniaMot’ (Ammonia Engine in German) project. Initiated by MAN with partners from industry and research institutes, it aims to define the steps necessary to produce a dual-fuel, medium-speed engine capable of running on diesel-fuel and ammonia. Supported by the German Federal Ministry of Economics and Technology (BMWi), and due to run for three years from December 2020, project partners include the University of Munich, Neptun Ship Design, WTZ and Woodward L’Orange.

The University of Munich TUM will employ a rapid-compression expansion machine to establish the fundamentals concerning the combustion of ammonia and will develop, together with MAN, the combustion models necesary for fast adaption of the technology to different engine sizes.

Neptun Ship Design will analyse international regulations to ensure technical and safety requirements in a encapsulated, modularised fuel system. Such scalable components are a prerequisite for the introduction of ammonia engines in shipping. A prototype of the fuel system itself will be used on the test engine at WTZ. NSD will work in close cooperation with MAN on a roadmap regarding which steps are necessary to use ammonia engines with all necessary ancillary systems in new ships and conversions.

WTZ is a specialist within the field of energy conversion and will utilise a high-speed test engine to develop a combustion concept for the new engine. This will be done in close collaboration with MAN and will also form the basis for defining any requirements for exhaust-gas aftertreatment.

Woodward L’Orange is a leading manufacturer of injection systems and will produce the injection system for the ammonia tests at TUM and WTZ. Together with MAN, the technology will be scaled up to large, four-stroke engines in the project.

MAN Energy Solutions will transfer the technology to large-bore, four-stroke engines and and prepare for commercial development and production.
