Emission Analysis of a DI Diesel Engine Fuelled with Biodiesel from Waste Tallow

In the current investigation ,an effort has been made to make use of tallow oil for biodiesel production. Tallow oil is non- edible oil and now considered as an alternate form of energy. The tallow biodiesel blends B10, B20, and B100 were used to study the emission characteristics of the fuel. The testing is done for different engine loads 50 and 80%, and the results are compared with neat diesel. In addition to the tallow blends, the nanofluid pentanol is added to the blends to increase the combustion and to reduce the emission of all toxic gases. The temperature of 60°C is maintained for processing the tallow. The transesterification process is carried out to convert the oil to biodiesel with recommended fuel properties. It is observed by employing, B100 the emission of carbon monoxide, hydrocarbon, and smoke opacity are reduced to 22, 32 and 36% respectively. On the other hand, the NOx emission is increased. The pentanol is future added to the blends to reduce the emission all gases particularly NOx. On the whole, it is concluded that tallow is a promising source of energy with lesser emission than diesel. This biodiesel is recommended when they mixed with nanofluids like pentanol.
