exhaust emissions - Opis:
- Due to the legal changes in the exhaust emission limits in the European Union meeting the new norms becomes more challenging for car manufacturers. The recent progress in the exhaust aftertreatment technology and commercially available aftertreatment systems. However, as the exhaust, systems become more and more complex the problem of high emissions in many engine-operating points that are not currently a part of the type approval tests remains. The article aims to address the limitations of the oxidation catalysts in current aftertreatment systems, mainly their light-off temperature, by investigating new options for in-cylinder catalysts. Placing the catalytic layer within the combustion chamber avoids a number of problems associated with these catalysts being a part of the aftertreatment system. Engine emission tests have been performed comparing the effects of using an in-cylinder Pt-Rh catalytic layer in relation to hydrocarbon and nitrogen oxides emissions. The viable methods of producing a catalytic layer on engine components along with the choice of components to use for catalytic surfaces have also been discussed.
