TEME2030+ - Technology Evaluation for Marine Engines for GHG Targets 2030+

Novel technology concepts for the effective reduction of greenhouse gas emissions from large gas-based marine engines

Potential comparison of external mixture formation & internal mixture formation

  • Engine tests of the individual combustion processes with gas pressure level up to 500 bar
  • 0D/1D engine process calculation & 3D-CFD analysis of engine processes
  • Characterisation of injectors using an injection rate analyser and high temperatur, high pressure injection chamber

Evaluation of renewable fuels

  • Substitution of the conventional pilot fuel with renewable biofuels
  • Hydrogen blended into existing natural gas

Potential assessment of EGR use

  • Development and application of an HD exhaust gas recirculation concept
  • Evaluation and potential assessment of engine tests with EGR rate up to 30%
  • 0D/1D Simulation to assist concept decisions

Optimisation of combustion chamber geometry

  • Analysis of variable compression ratios
  • Evaluation of newly manufactured piston prototypes
  • 3D-CFD used for development of of optimum piston design for direct gas injection combustion processes

Further investigations: Post engine methane reduction, Crankcase atmosphere analysis, Variable valve timing and more
