|The aim of this proposal is 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 is 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 will be tested under realistic conditions for developing modalities and strategies for feedback control of the system. Finally, LCA/techno economic assessment for the developed technologies will be carried out.
To produce multifunctional (micro fluidic/catalytic/electrochemical/electric) micro/nano-scale porous sensing elements by integrating:
i) 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;
ii) 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;
iii) 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.
The main activities of the proposed project will be structured around the following Work packages:
- Development of new, miniature diagnostic hardware elements for the detection of the soot mass loading and the triggering and detection of regeneration of a particulate filter in diesel exhaust;
- Procurement and screening of diagnostic hardware elements for the detection of NOx concentrations in diesel exhaust;
- Development of the requisite algorithms for the simulation of diagnostic element responses and the production of novel virtual sensor modules;
- System integration aimed at coupling the hardware diagnostic element components and software modules in a single sensor platform to be tested on a modern diesel engine;
- Development of modalities and strategies for feedback control of the sensor platform;
- Performance of Life Cycle Analysis and techno-economic assessment for the developed technologies.
