Mix Oil Biodiesel Blend’s Performance Characteristics with Energy Audit

The mix oil biodiesel blend’s performance and emission characteristics have been evaluated by application of method of energy audit. The objective of this study is to make use of a method of energy audit for biodiesel engine, which reduces time to investigate biodiesel engine by choosing important performance and emission parameters first. After analysing those parameters, if those parameters are found satisfactory, then analysis of other parameters would be done. And if those parameters are found unsatisfactory, there is no need to analyse further thus saving time and money. In this experimental study, use of least square method to find best fit equation of regression and coefficient of determination have been done. Time and energy can be saved with the application of this method. Heat flow analysis, brake specific energy consumption, friction power, and smoke have been evaluated. These all parameters have been found satisfactory. In least square method, relationship between these characteristics and biodiesel blends has been found out at 3.5 kW. The best fit equation of regression and coefficient of determination have also been measured. B10 mix oil biodiesel could be used as fuel with efficient conversion of heat energy among all tested biodiesel blend. However, diesel’s brake thermal efficiency is the highest.
