The continuing reduction of the emissions of diesel engines has caused an increasing complexity of calibration and expensive aftertreatments of the exhaust gas. These issues have a potential for being relaxed if the NOxNOx and particulate emissions are integrated into a feedback loop. For this purpose, a novel controller is developed. A model-based observer for the emissions is used to overcome the relatively slow dynamics of the available sensors. Furthermore, the controller includes self-calibration of the EGR. The experimental validation of the control structure shows that different emission strategies are feasible with just a minimal calibration effort.
► New controller for the engine-out particulate and NOxNOx emissions of diesel engines.
► Model-based observer for the engine-out emissions to cope with sensor lag and delay.
► Automatic calibration of the EGR reference value.
► Experimental validation with different emission strategies and minimal calibration.
