Abstract
Now a days population intensity of vehicle rapidly increase so cost of the fuel like petrol diesel, etc. are increase highly and emission of the vehicle create many problems like affecting human health, cause the depletion in ozone layer, affecting the photosynthesis of plants, etc. so reducing the pollution diesel is blended with the n-Butanol at various different proportion. First n-Butanol is converted into fuel by using transesterification by adding acid catalyst. Now n-Butanol is blended with diesel fuel at various proposition 5%, 10% and 15% by total volume of fuel. The emission characteristics of 5%, 10% and 15% of blending of n-butyl alcohol with ordinary diesel to record and evaluate the emission characteristics of blending fuel and ordinary fuels. The emission test at 80% load revealed that, the CO, HC and smoke density are increased by 22.222%, 28.571% and 14.757% respectively for 10% addition of n-butyl alcohol with diesel. The NOx emission while using 10% n-Butanol blend with diesel is decreased by 19.131% at 80% load. n-Butanol increase the atomization of the fuel so complete combustion can take place and low calorific value of n-butyl alcohol so heat release during combustion of engine rapidly decrease so NOx emission significantly reduce.
