Performance and emission of homogeneous charge compression ignition engine with modified volume of displacements using kerosene fuel

Homogenous Charge Compression Ignition (HCCI) is a promising combustion process which has lower fuel consumption and emits very low nitrogen oxides (NOx). It is one of the few solutions on hand that looks very promising to address the issues on the atmospheric air pollution and depleting fossil f...
