Abstract
In today’s relevance, it is obligatory to devise the use of diesel in an environmentally benevolent way. So, in this experimental investigation, an attempt was made to increase the combustion efficiency, and thereby to increase the performance and to reduce the exhaust emission by blending an alkane known as n-pentane at 10% by volume with diesel. The performance, combustion and emission characteristics observed while using blended fuels were analyzed and compared with that of diesel as fuel without adding the alkane. The performance analysis reported that, at 80% load, the brake thermal efficiency was increased by 3.684% for the blending of 10% n-pentane with diesel. The maximum heat release rate and peak cylinder pressure were decreased whereas the cumulative heat release was increased for the blended fuel. The emission test concluded that, the smoke density was increased by 0.781% for the blending of 10% n-pentane with diesel. The NOx emission was decreased by 14.634% while using the blended fuel.
