... as a disturbance in the in-cylinder pressure dynamics. Thus, the wall temperature in each cylinder can be estimated, on a cycle-by-cycle basis, by the disturbance observer methods in finite crankshaft angles. Furthermore, to reduce the cylinder wall temperature estimation errors caused by the high-frequency noises...

...Ming-Feng Hsieh; Junmin Wang This paper presents an experimentally validated control-oriented model and an observer for diesel oxidation catalyst (DOC)-diesel particulate filter (DPF) system in the context of exhaust gas NO and NO 2 concentration estimations. NO and NO 2 have different reaction...
