10 New emissions requirements impact on fuel consumption and smoke 10 Wärtsilä G. Rizzetto
11 New emissions requirements impact on fuel consumption and smoke Severe NOx emission limits will strongly penalize SFOC and smoke. New technologies development to find a compromise between these contesting objectives/constraints. Players to reach specific emission levels: Fuel quality to avoid scrubber or particulates filter High Exhaust Gas temp. according to the fuel sulphur content for SCR use To limit the SCR UREA consumption NOx must be reduced at the engine stage 11 Wärtsilä G. Rizzetto
12 New emissions requirements impact on fuel consumption and smoke Tier2 is the NOx level we are currently facing by means of: a. Low NOx combustion tuning High compression ratio & retarded inj. timing TDC) Triangular injection rate shape Optimized injection pressure in the 50% - 75% load range (CR engines) Combustion space optimization (piston top and injector geometry) b. Turbo Charging Remarkable Miller timing Valve timing flexibility Lower receiver temperature Early inlet valve closure: Shorter compression stroke Lower charge temperature inside cylinder 12 Wärtsilä G.
