Abstract
The growth of energy demand and limited fossil fuel resources lead to renewable energy development such as vegetable oils and animal fats or their derivatives. In the present work, the valuation of waste fish fat by the pyrolysis technique with the presence of catalyst to produce biofuel for diesel engines. As a result, fuel undergoes good combustion and hence there is a significant improvement in performance and reduction in emissions. The brake thermal efficiency of neat biofuel is 32.4% at 80% load which is very high compared to neat diesel (29.98%). The combustion duration and ignition delay are decreased with neat biofuel due to high oxygen content and high cetane number of biofuel. The main problem with the use of neat biofuel in diesel engine is high NOx emissions at all loads. Addition of diesel with biofuel reduces the NOx emissions significantly from 917ppm to 889ppm at 80% load with an optimum blend of B80D20. There is a slight decrease in brake thermal efficiency and increase in particulate emission with this blend. The overall results show that by adding small quantity of diesel with biofuel decreases the NOx emissions significantly and approaches the performance of neat biofuel.
Highlights
The diesel engine is a major tool in the day-to-day life of modern society
Biofuel from waste fish fat offers the advantage of freely mixing with diesel and these blends can be used in the existing diesel engine without any modifications
The biofuel and diesel were taken in separate container it was measured for the different proportions by volume basis
Summary
The diesel engine is a major tool in the day-to-day life of modern society. It powers much of our land and sea transport, provides electrical power, used for farming, construction and industrial activities. The fossil fuel scarcity and pollutant emissions from diesel engines have become two important problems of world today. Biofuels have been gaining popularity recently as an alternative fuel for diesel engines [4,5,6]. Biofuels can be used in any diesel engine, usually without any modifications. It boasts a reduction in toxic emissions (except NOx emissions) compared to diesel fuel [7,8,9,10]
