Performance Assessment and Emission Characterization of Diesel-Fueled Homogeneous Charged Compression Ignition Engines

The Homogeneous charge compression ignition (HCCI) combustion is an alternative to current engine combustion systems and research in HCCI is being carried out to use it as a method to reduce emissions. In this research performance and emission characteristics of HCCI combustion has been investigated experimentally. Experiment was performed in modified single cylinder diesel engine which has conventional mode of starting and then followed by HCCI mode. The basic requirement of the HCCI engines is homogeneous charge preparation, which is attained by using port fuel injection strategy. An external device was used for fuel vaporization and mixture formation.
