Experimental Investigation on Performance and emission characteristics of HCCI Engine fueled with diesel and Jatropha Bio-Diesel

Pollution is a major issue worldwide. In that, pollution from automobile exhaust emission is the major concern due to HC, CO and NOx emission gives hazardous effect on environment. Current pollution and strict pollution norms reducing exhaust emissions and increasing the fuel economy of internal combustion engines. To overcome these issues a technology is needed to be developed and HCCI is such a technology, which is highly efficient as well as less polluting. HCCI is a hybrid of both spark ignition (SI) and compression ignition (CI) combustion concepts. It is also need of replacement of convectional fuel like petrol and diesel with alternative fuels. HCCI engine fueled with biodiesel can be address both issues with alternation of convectional fuel with alternative fuels. By HCCI, it can achieve both homogeneous charging with high compression ratio. Homogeneous charge reduces HC and carbon shoot emission while higher compression ratio gives higher thermal efficiency. Present work is focused on performance and emission characteristics of HCCI engine fueled with Jatropha biodiesel.
