Effects of biofuel from fish oil industrial residue – Diesel blends in diesel engine

Abstract

The present work aims to produce biofuel from fish oil industrial residue and to test the biofuel in diesel engine. A 4.5 kW at 1500 rpm single cylinder air cooled direct injection diesel engine was used for the present experimental work. The experimental results show that the brake thermal efficiency marginally increases with biofuel from 29.98% (neat diesel) to the maximum of 32.4% with biofuel at 80% of maximum load. Also experiments were conducted with different blends of biofuel and diesel (B20 and B40). Though the NO x emissions are high with neat biofuel and blends, the other emissions like CO, HC and particulate matter (PM) are decreased. The PM emissions decrease when the percentage biofuel increases in the blend. It reduces from 8271 ng/s with neat diesel to 8137 ng/s with B40. It further reduces to the minimum of 7842 ng/s with neat biofuel. The cylinder peak pressure increases as the biofuel quantity increases in the blend. The rate of premixed combustion increases with neat biofuel and its blends than neat diesel. Addition of biofuel with diesel decreases the combustion duration and ignition delay due to higher cetane number of biofuel.

Impact of biodiesel fuel on cold starting of automotive direct injection diesel engines

“…In this cycle, the CO 2 released into the atmosphere, when the biodiesel fuel burns, is recycled by growing plants, which are later converted into fuel. Since the sulfur and the aromatic content of biodiesel fuels are negligible while their oxygen (O 2 ) con-centration is substantially high [7], significant reductions of sulfur dioxide (SO 2 ), soot, carbon monoxide (CO) and unburned hydrocarbons(UHC) can be achieved [8,9,10].…”

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

“…The animal fats have achieve the better feet recently in terms of all emission parameters owing to the presence of triglycerides. The emission characteristics of the biodiesel are less due to the higher oxygen content than conventional diesel fuel [3]. In recent days, the use of animal fats for feeding is declined due to the changing food habits of people.…”

Comparison Tests of Fossil Diesel Fuel and TBK-Biofuel

“…These disadvantages can be compensated by decreasing in exhaust gas emission in point of certain components because of their adherent oxygen content (Guarieiro et al, 2014;Mrad et al, 2012;Lapuerta et al, 2010;.…”
