Aftertreatment control and adaptation for automotive lean burn engines with HEGO sensors

Aftertreatment control and adaptation for automotive lean burn engines with HEGO sensors

Control of aftertreatment systems for lean burn technology engines represents a big challenge, due to the lack of on-board emission measurements and the sensitivity of the hardware components to ageing and sulphur poisoning. In this paper, we consider the control and adaptation of aftertreatment systems involving lean NOx trap (LNT). A phenomenological LNT model is presented to facilitate the m...

Dynamic Optimization of Lean Burn Engine Aftertreatment

The competition to deliver fuel e cient and environmentally friendly vehicles is driving the 1 2 Submitted to Journal of Dynamics Systems, Measurement, & Control automotive industry to consider ever more complex powertrain systems. Adequate performance of these new highly interactive systems can no longer be obtained through traditional approaches, which are intensive in hardware use and nal co...

Approximate Dynamic Programming Solutions for Lean Burn Engine Aftertreatment

The competition to deliver fuel e cient and environmentally friendly vehicles is driving the automotive industry to consider ever more complex powertrain systems. Adequate performance of these new highly interactive systems can no longer be obtained through traditional approaches, which are intensive in hardware use and nal control software calibration. This paper explores the use of dynamic pr...

Car Exhaust Pollution Control LEAN BURN ENGINES AND THE CONTINUING REQUIREMENT FOR PLATINUM - CONTAINING AUTOCATALY STS

Over the past twenty years catalysts containing platinum group metals have become the preferred means of limiting the polluting emissions of carbon monoxide, hydrocarbons and nitrogen oxides from motor vehicles. However, from time to time methods of exhaust control are proposed which appear to off.. a viable alternative to autocatalysts. Europe has been slow to adopt emission control standards ...
