Optimization of Engine Control Strategies during Transient Processes Combining 1-D and 3-D Approaches. SAE 2010-01-0783

Popis výsledku v původním jazyce

The goal of this study is to improve the 1-D methodology by optimizing the control strategies. Also, additional independent parameters are introduced to extend the 3-D data library for interpolation. The data points for the 3-D simulations are selected in the vicinity of the expected trajectories obtained from the independent parameter changes, as predicted by the transient 1-D simulations. Boost pressure, EGR and relative A/F limit control procedures are compared to improve the engine response to speed/load requirements at minimized emission levels. The influence of transient operations on the behavior of the prescribed EGR flow rates is demonstrated. Since this method reduces the simulation time, it is possible to predict emissions during standardized unsteady tests in real time. Therefore, this 1-D simulation method is a useful tool for engine optimization and control, that is, it allows the minimization of the fuel consumption while meeting legislated emission standards.
