Abstract
In today’s relevance, the application of diesel engine holds an important role. Though the economic and environmental aspects do not support the use of diesel nowadays, it is impossible to accomplish the habitual livelihood without diesel engine. Therefore it is mandatory to devise the use of diesel in an economic and environmentally benevolent manner. In the present scenario, the combustion efficiency of compression ignition engine is very low. The improper combustion leads to poor efficiency and the emission of incomplete combustion by-products. Hence it was planned to increase the combustion efficiency and thereby to increase the performance and to reduce the exhaust emission. The combustion efficiency of diesel can be further improved by reducing the ignition delay period. The present work was aimed at to improve the performance and to reduce the emission by using different chemical compounds at a definite proportion by volume with diesel, also to compare the performance and emission of the engine while using different blended fuel. For experimentation, different blended fuels in which various chemical additives blended with diesel were used as fuel. The observations were analyzed and the results were compared with the performance and emission characteristics of the engine while using diesel without any additives as fuel. The performance characteristic curves revealed that the addition of additives enhances the combustion efficiency of diesel; the outcome of the emission test concluded that there was an appreciable reduction in emission of combustion by-products.
