Diesel Engines Emission Reduction Applying Cerium Nanometric and Ceriun Oxide in Piston Hard Anodized.
[INTRODUCTION] The Ceriun Nanometric Properties applied in piston head promote a catalystic reaction in combustion chamber and avoid the Particulate Matter (PM) and Nitrogen Oxide (NOx) formation. The reaction as a result of material characteristic in “breathe in and out” Oxigen atoms spontaneously.
[METHODOLOGY] The methodology evaluated in this project as a consequence of chemical reaction promoted by non stoichiometirc condition between Cerium and Oxigen compounds (maintain the Oxygen without his decomposition). The Oxigen can be liberated from internal combustion to exhaust system. When introduced Cerium Nanometric on the piston head the reaction can reduced effectively decreasing the NOx and PM emission and convert CO in CO2.
[RESULTS] Tests in dynamometer are under development and emissions measurements will be evaluated to confirm the real NOx and PM level.
[CONCLUSION] The characteristic of Cerium Oxide material applied in all engine piston during Hard Anodization and Cerium nanometric applied in engine piston head can promote the catalysis reaction necessary to reduce the NOx and PM according to Euro IV Legislation Emission requirements (EPA - Environmental Protection Agency').
