Abstract
Most promising alternative source available for fossil diesel in India is the Pongamia pinnata biodiesel (Karanja biodiesel in the Indian context). The characterization of biodiesel plays an important role in engine emission and performance. Due to oxygenation the biodiesel has low higher heating value than fossil diesel hence it is necessary to study the effect of different physio-chemical properties on higher heating value. Experimentations were conducted on 11 samples on the basis of Volume % for Pongamia Pinnata biodiesel and diesel blends in the step of 10 varying from 0% (Fossil diesel) to 100% (Pongamia pinnata biodiesel). A retrospective investigation is conducted for characterization of biodiesels and different physio-chemical properties are correlated as a function of Higher Heating Value (HHV). By the traditional statistical technique of regression analysis the correlations can predict the HHV values with the accuracy of R2=0.9907 and uncertainty of ±6.19%. HHVs obtained by performing experiments and by predicted correlations are compared with the correlations available in open literature. The study reveals that the properties of kinematic viscosity and density have a strong correlation with HHV as compared to cetane number and flash point.

The physio-chemical properties of fuels are correlated with other properties for establishing correlations of density, kinematic viscosity, flash point, cetane number and higher heating value
The Higher Heating Value (HHV) predicted through the individual physio-chemical properties correlations from flash point and cetane number that are having very less accuracy of prediction i.e. R2 = 0.61 to 0.98
Summary
Introduction and LiteratureReview https://doi.org/10.10 51/matecconf /201927201009The important issue confronting at the global level is energy crises [1]. There are various kinds of energy resources available in the nature but the fossil fuels contribute more than 80% of the world energy requirement. Fossil fuels reservoirs are depleting very rapidly throughout the world [3]. Renewable energy sources are one of the alternatives available in place of fossil fuels. According to Petroleum Planning and Analysis Cell the consumption of diesel fuel in India and its equivalent CO2 liberation for the year 2016–2017 was 196.48 million tons and 2454.97 million tons respectively. Future energy demands can be fulfilled by biodiesel.
