Determination of the operating parameters to be controlled Determination based on: • Simulation results of the powerplant performance performed in WP5 (Powerplant simulation) • Engine-specific correlation between operating prameters and emissions obtained in WP6 • Available control options for the conventional and intelligent engines. Basic selected controlled parameters • Injection timing • Choice of injection profile • Exhaust valve open timing • Exhaust valve close timing • Hydraulic supply pressure (injection pressure) Athens, October 8, 2003 Final Presentation
Validation of control schemes Development of engine running modes • Low Emission mode • Economy Mode 4.0 170 160 150 Fuel Injection & Exhaust Valve Timing Cylinder Pressure Fuel Oil Consumption Low Emission mode Low Emission mode Economy mode Economy mode Exhaust valve close Pmax Pcomp Low Emission mode Economy mode 2.0 140 [g /kW h ] 0.0 -2.0 Timing [bar abs.] 130 120 110 100 Exhaust valve open -4.0 90 -6.0 80 Injection Timing 70 50 60 70 80 90 100 110 50 60 70 80 90 100 110 50 60 70 Engine 80 Load [%] 90 100 110 Engine Load [%] Engine Load [%] Athens, October 8, 2003 Final Presentation
