Work Package 8: Integrated SCR and combined SCR and filter

Objectives

Two-stroke:

• Investigation of High Pressure SCR process; injection, mixing, decomposition and flow distribution with the aim of making the SCR components compact while still maintaining the same  high performance as best available technology today
• Designing of engine integrated High Pressure SCR system with unaffected engine footprint and only slightly affected gallery arrangement around the engine        
• Testing of compact High Pressure SCR component performance on 4T50ME-X test engine

Four-stroke: 

• 80% PM reduction with after-treatment system (based on IMO Tier II engine out emissions)
• 80 % NOx reduction with after-treatment system to reach IMO Tier III limits
• Investigate necessary installation space for after-treatment system SCR on DPF within IMO Tier III SCR system
• Adaptation and integration of the after-treatment system (SCR on DPF) on a marine Diesel engine
