Abstract
After the industrial revolution, energy became even more important to humanity's ability to maintain a high quality of life and continued economic growth. Energy still comes mainly from fossil fuels. However, the reserve will soon be depleted due to the continued use of fossil fuels. As fuel prices are skyrocketing due to declining supply rather than demand. That is why researchers around the world have been constantly searching for alternative fuels in recent years. The blend are (20%,40%,60%, 80% and 100% based on volume) aim is improve the performance, reducing NOX,CO,HC,𝐶𝑂2, and smoke Opacity emissions and global dependence on fossil fuels. Vegetable oils have a higher viscosity than regular diesel fuel, making their use as fuel for diesel engines problematic. Problems caused by high viscosity are solved by a variety of approaches and procedures. One of these techniques is fuel mixing. The main objective of the current innovative work is to conduct experimental research to evaluate the performance and emission characteristics of tamarind seed biodiesel and its blends in a single cylinder diesel engine. It is crucial to develop alternative fuels that are as effective as conventional fuels to take into account universal protection and the desire for a long-term supply of standard diesel fuel. According to the combustion analysis adding biodiesel to conventional fuel causes the peak pressure inside the cylinder decrease, BSFC and BTE are increasing in the TMBD20 is the best blend when compared to the other blends still in use because its brake thermal efficiency (31%) is close to that of conventional diesel (34%) at full load. As a result, it is advised that the B20TME be used as biodiesel in diesel engines without requiring any engine modifications.
