Performance and Emission Characteristics of a C.I Engine with Cerium Oxide Nanoparticles as Additive to Diesel

Nithin Samuel, Muhammed Shefeek K

Abstract: An experimental investigation is carried out to establish the performance and emission characteristics of a compression ignition engine while using cerium oxide nanoparticles as additive with neat diesel. The work has been divided into two phases. In the first phase, pure diesel is tested in a CI engine and preparation of nanoparticles. Then in the second phase, performance characteristics are studied using the fuel added with nanoparticle in a four cylinder four stroke engine. The cerium oxide acts as an oxygen donating catalyst and provides oxygen for the oxidation of CO or absorbs oxygen for the reduction of NOx.
