The aim of this proposal was to develop an integrated sensor platform for next-generation emission control systems such as particulate (soot) filters and nitrogen oxides converters through systems integration of micro/nano-materials technologies, virtual sensor simulation algorithms and instrumentation of emission control devices. This was in direct response not only to future market potential of these technologies, but also to explicit statements of the EC to push sensor development for such applications by 2008. After incorporating software modules with the sensor elements the integrated device was tested under realistic conditions for developing modalities and strategies for feedback control of the system. Finally, LCA/techno economic assessment for the developed technologies was carried out. 

Objectives: 
To produce multifunctional (micro fluidic/catalytic/electrochemical/electric) micro/nano-scale porous sensing elements by integrating: 

1. A sensitive but affordable sensor platform for the detection of soot nanoparticles (detectable mass between 1-30gr/m2 of filter area) and nitrogen oxides concentrations (< 500ppm) for on-line emission monitoring of next-generation emission control devices like diesel particulate filters and deNOx converters;
2. Robust and computationally efficient multi scale algorithms simulating the system performance, leading to the production of virtual sensors, with substantial overall system cost reduction benefits;
3. Fundamental knowledge on the functioning performance of the new sensor platform interfaced with next generation emission control systems on state-of-the-art diesel engines.
