2. Modeling, Control and Optimization of theTransient Torque Response in DownsizedTurbocharged Spark Ignited Engines
Abstract : Increasing demands for lower carbon dioxide emissions and fuel consumption drive technological developments for car manufacturers. One trend that has shown success for reducing fuel consumption in spark ignited engines is downsizing, where the engine size is reduced to save fuel and a turbocharger is added to maintain the power output.
