AmmoniaMot 2

Development of a full-scale demonstrator engine with modular fuel system technology for operation on renewably produced ammonia as a marine fuel

Subproject: Experimentally supported development of 0D/1D simulation methods for analyzing the effects of renewably produced ammonia on lubricant, injector, and exhaust aftertreatment technology when used in large engines

Project Objective:

The “AmmoniaMot2” project is a follow-up to the “AmmoniaMot” project, in which a two-stroke ammonia engine was successfully developed and tested. Building on the insights gained there, the aim of “AmmoniaMot2” is to develop and operate a medium-speed, four-stroke, dual-fuel demonstrator engine designed to run on renewably produced ammonia. The main focus areas include validation of the injector technology, fuel conditioning, engine control, lubrication oil, and exhaust aftertreatment systems.

 

LKV’s Contribution:

Within the overall project, LKV is responsible for the following subprojects:

  • Simulation technologies for model-based representation of the NH₃ dual-fuel combustion process and the required exhaust aftertreatment systems
  • Exhaust aftertreatment technologies for large engines operating on NH₃
  • Injection technologies for introducing NH₃ into the combustion chamber
  • Lubrication oil technologies for large engines operating on NH₃

As part of the focus area Simulation Technologies, novel 0D/1D cylinder models will be developed and applied for the model-based representation of ammonia combustion. In addition, the exhaust aftertreatment will be simulated within a 0D/1D environment. The exhaust aftertreatment technologies include evaluating commercially available catalysts and investigating the underlying reaction mechanisms in exhaust gas treatment.

The evaluation and optimization of ammonia injection will be carried out using optical measurement techniques. Here, the development of an optical test setup and the measurement of injection components are the main priorities.

For the analysis of lubrication oil technologies, commercially available lubricants and additive technologies for use in large ammonia-fuelled engines will be assessed. The interactions between ammonia-contaminated lubricants and engine component materials will be specifically investigated, and novel analytical methods for characterizing engine lubricants in ammonia operation will be developed. Furthermore, research needs will be identified to strategically advance future developments.
