Abstract: From the aim of consideration of the universal protection and the interest for long-run provides of standard diesel fuels, it becomes essential to develop alternative fuels as good as with standard fuels. To exchange traditional diesel, biodiesel is a safe alternative fuel. The Transesterification process is adopted to prepare the tamarind seed oil methyl esters. In the current study the effects of performance, emissions and combustion characteristics has been investigated in a single cylinder four stroke vertical diesel engine for 20%, 40%, 60%, 80% and 100% by volume tamarind seed oil methyl esters mixed to diesel. From experimental results, it is determined that there is decline in brake thermal efficiency and raise in the brake specific fuel consumption by application of the blends of tamarind seed biodiesel in the diesel engine, owing to the smaller calorific value of the tamarind seed biodiesel and its blends. However, the tamarind seed biodiesel notably reduced the emissions such as carbon monoxide, hydrocarbons and smoke density, while the nitrogen oxide emissions are increased. The engines combustion analyses showed that adding tamarind seed biodiesel and its blends to the base diesel fuel reduced the peak cylinder pressure. These results showed that the tamarind seed biodiesel could be commissioned as an alternative fuel in the engine exclusive of any engine alterations.
