Abstract
In today’s applications, the use of diesel engine holds a key role. Even though the environmental features do not satisfy the use of diesel nowadays, it is not possible to accomplish the habitual livelihood without diesel engine. Therefore it is mandatory to devise the use of diesel in an environmentally benign way. In the present scenario, the combustion efficiency of compression ignition engine is very low. The improper combustion of fuel inside the engine leads to poor performance and emission of incomplete combustion by-products. Hence it was planned to increase the combustion efficiency and thereby to increase the performance and reduce the exhaust emission. For the experimentation, blended fuels of various proportions were prepared by blending Diethyl ether as additive with diesel. The observations were analyzed and the results were compared with the performance and emission of the engine using diesel as fuel without any additives. The performance characteristic curves revealed that the addition of additives enhanced the combustion efficiency of diesel; the outcome of the emission test also revealed that there was an appreciable reduction in emission of combustion by-products.
