TECHNOLOGY – MD SYSTEM LAYOUT

• Pilot-fuel assisted diesel combustion concept

• Methanol is combusted according to the diesel process. Methanol is injected close to TDCand ignited by a small amount of diesel pilot fuel.

METHANOL ADAPTATION

© Wärtsilä

• Adaptation of proven engine technology, minor modification to the engine• Not viewed as major conversion• No reduction in efficiency or output running on methanol• Load response unchanged, full fuel redundancy• Existing fuel or ballast tanks can be converted to methanol tanks• Short off-hire time, can be done engine by engine• Lower thermic load on the engine• Much lower NOx, SOx, and PM (particulates), good base for future ECA regulations

CHALLENGES & FUTURE RECOMMENDATIONS

Technical• material choice important‒ special alloys, coatings and sealing materials

• design criteria important‒ special design for sealing surfaces

Economical• price disconnection from bunker fuel market• availability, >60 export/import terminals, how to bunker?

Recommendations:‒ Variable injection timing for both pilot and main fuels‒ Separate pilot fuel injector -> minimizing the pilot fuel amount‒ Water-blended methanol -> lower NOx‒ Pure methanol mode – diesel combustion cycle – hot surface assisted ignition
