9 Wrtsil 1 August 2012 DBAA001148 500 vs. 580 kW/cyl16% higher output compared to current

Main design actions:Pmax increased to 230 barNew turbo charging system with increased pressure ratioInjection system: conventional with increased pressure and outputNew reinforced engine block and crankshaftNew cylinder head, common with W34SGNew high strength pistons

10 Wrtsil 1 August 2012 DBAA001148 Power Plants 20V32With Two Stage Turbocharging

11 Wrtsil 1 August 2012 DBAA001148 460 vs. 500 kW/cyl9% higher output compared to current

Main design actions:Pmax increased to 230 barNew two stage turbo charging system with increased pressure ratioInjection system: conventional with increased outputNew reinforced engine block and crankshaftNew cylinder headNew high strength pistons and connecting rods

W20V32, Whats updated?12 Wrtsil 1 August 2012 DBAA001148 Upgraded conventional fuel injection system Higher pump capacityNew cylinder head & equipments Commonality to gas engines Possibility for Higher design pressureValve timing adjustments Advanced Miller timingDeveloped starting air system Less starting air consumption Faster start sequencePossibility to Increased Pmax Higher outputHigh strength pistons Allows higher output

Reinforced crankshaft Allows higher outputAdded engine block rigidity Reducing engine vibrations Reinforced for heavy TC package.High strength connecting rod Allows higher outputNew more efficient chargersNew charge air system

Turbocharging system13 Wrtsil 1 August 2012 DBAA001148 New improved TC bracketHP turbochargers: ABB P145-MLP turbochargers: ABB Z150-MTC washing systemProduction designSPEX same manifold as todayHigher charge air pressure up to 7,35 bar

Note: 2-stage turbocharging results in lower exhaust gas temperatures. Engine can therefore not be combined with a Nox reduction unit (SCR).
