A Study on In-Cycle Control of NOx Using Injection Strategy with a Fast Cylinder Pressure Based Emission Model as Feedback
Författare
Summary, in English
Studies of injection strategies show that one of the feasible approaches, using a solenoid injector to control NOx, is a split-main injection based strategy. Results suggest that it is hard to control the NOx in a satisfactory manner. Really low injection pressures and long injection durations had to be applied to achieve control of the NOx formation. This also implies inherently high smoke emissions. The strategy allows NOx reduction but measurement and emission estimation results indicate that the delay between fuel injection and the maximum NOx concentration is too long. The NOx target value defined could never be satisfied using the feedback-based split-main injection strategy. Prediction-based feedback will be necessary to improve the control.
