Modelling and Observation of Exhaust Gas Concentrations for Diesel Engine Control

Abstract: A mis abuelos Manolo y Feli, a Mikel, Ama y Aita.Shine on you crazy diamond.g Resumen. La presente Tesis Doctoral estudia la observación en tiempo real de la concentración en el colector de escape de losóxidos de nitrógeno (NO x ) y del dosado (λ ¡1 ) en motores diesel sobrealimentados. Para ello se fusionan dos fuentes de información diferentes:• Sensores capaces de proporcionar una medida de dichas variables, y• modelos orientados a control que estiman estas variables a partir de otras medidas del motor.El t… Show more

“…Taking into account that the ECU-based estimation contains the high-frequency information of the actual CO 2 emissions but has some drift, the analyser signal (slow but accurate in steady state) can be used to compensate this drift as proposed in Blanco-Rodriguez 16 for the NO x emissions and λ estimation. In particular, the proposed method is based on observing the bias θ between the measurement y and the estimation u , considering the measurement dynamics.…”

“…The problem on making PICE in PP environmentally safe is tackled in a large number of fundamental scientific studies [1][2][3][4][5][6][7], which testifies to its relevance. The latter is proved by the information in analytical reviews based on the results of annual congresses of the Society of Automotive Engineers (SAE) [8][9][10].…”

“…This can be addressed by the development of a miniature sensor-based platform that is capable of being instrumented in the vehicle to collect and quantify emissions rates associated with driving performance over a long period of time. Current on-board Zr-O2 NOx sensors are compact, comprise of reduced warmup time, and demonstrate improved accuracy(Blanco-Rodriguez, 2013;Hofmann et al, 2004). Utilization of tailpipe NOx sensor in conjunction with an ECU data logger can potentially serve as a complementing or alternative cost-effective medium to monitor real-world NOx emissions rates.…”
