PERFORMANCE OF CI ENGINE USING WCSFO BIODIESEL BLEND – A REVIEW

Mechanical Engineering

In recent year, energy is the basic need of everyone in the world and also the energy consumption is increasing with time. Basic source of energy are fossil fuel such as coal, natural gas and petroleum products such as gasoline and diesel. But these sources of energy are limited in quantity and they are non-renewable. They will not be available in nearby future for use hence growing concern regarding energy resources and environment has increased interest in the study of alternative sources of energy. To meet increasing energy requirement, these have been growing interest in alternative fuel like biodiesel to provide a suitable diesel oil substitute for internal combustion engine. Biodiesels are offers a very promising alternative to diesel oil since they are renewable and have been similar properties. One of the economical sources for biodiesel production which doubles in the reduction of liquid waste and the subsequent burden of sewage treatment is waste cooking oil. This research work aims to carry energy and exergy analysis of Compression Ignition (CI) Engine to study performance and its characteristics. The thermal efficiency and the energy losses in the system are calculated from the 1st law of thermodynamics, while the maximum work output or exergy is calculated from the 2nd law of thermodynamics. Energy analysis is carried out for biodiesel blends (B10 to B50 with increment of 10). From this analysis best performed blend was chosen and exergy Analysis is carried out to check the effect of change in Compression Ratio (CR) and Injection Pressure (IP) on the exergy efficiency. Exergy analysis also allows us to find out some feature like availability which cannot be possible with the use of energy analysis.
