Performance, Emission and Combustion Characteristics of Aloevera-diesel Emulsified Fuel in a Di Diesel Engine

Abstract

Abstract Nowadays mankind are very particular about the usage of the energy in most effective manner by keeping the view of less adulterating the atmosphere, are the key aspects of many scientists all around the world. In this particular study, the aloevera diesel has been chosen as the primary fuel and studies have been conducted in emission pollutant characteristics, by choosing appropriate diesel engine. Further to this, stable emulsions have been produced by using aloevera and the same was mixed with diesel as the ratio of 5% and 10% as compound. Moreover, span 80 and tween 80 are used as the surfactant with HLB balance of 9.95. Similarly, the emulsions are prepared with help of mechanical stirrer for exact duration of 30 minutes. In order to carry out the experimental investigation process, single cylinder diesel engine was used with data acquisition system. The entire analyses are carried with two set of methods such as no load and full load. The performance and combustion characteristics such as heat release, combustion pressure, thermal efficiency and specific fuel consumption of brake were measured. Likewise, emission parameters such as CO, HC, NOx and CO2 are measured by using AVL Di-gas analyzer. It was noticed that, increased peak cylinder pressure and greater heat release rate on account of longer ignition delay period. Additionally, increase in engine performance and corresponding reduction in exhaust emission also have been observed upon using alovera emulsified diesel fuel.
