“…The highest Lower Heating Value (LHV) was 40.594 MJ/kg in the B20 sample with 0.2% lemon essential oil additive, and the lowest was 38.276 MJ/kg in the B20 sample. With increasing concentrations of lemon essential oil, the heating value increases [6]. The heating value is proportional to the sample density.…”

“…The flash point of lemon essential oil is 48 °C [24]. The flash point of a mixture of biodiesel and lemon essential oil is lower [6]. The bioadditive's catalytic cracking effect causes the fuel hydrocarbon molecules to break down into smaller particles, lowering the flash point.…”

“…Biodiesel can be used as an alternative fuel, because it has a physical and chemical composition that is not too different from diesel fuel, and also has a high level of environmental friendliness compared to fossil fuels [3,4]. Biodiesel is a methyl ester fatty acid, where the biodiesel used comes from vegetable oil or animal fat which is made through esterification and transesterification processes [5,6]. Palm oil biodiesel has a high viscosity value, low heating value with a higher amount than essential oils [7].…”

This study is motivated by the depletion of fossil fuels in nature, which is inversely proportional to the higher level of fuel oil consumption, so the need for alternative fuels, namely biodiesel. Biodiesel can be made using waste cooking oil because of its abundant quantity, low price, and not being reused. One of the efforts to achieve energy conservation and improve fuel quality is using bioadditives. A lemon essential oil can be used as a bio-additive because it is easily soluble in fuel and its oxygen-rich content can reduce the rate of fuel consumption. The process in this study is to produce biodiesel with waste cooking oil (WCO) using a transesterification process. Biodiesel samples containing the bioadditive lemon essential oil on B20 biodiesel with varying volume fraction (0%; 0.1%; 0.15%; 0.2%). In general, this research can be done in three steps. The first step is the characterization of the compound composition (GCMS) and functional group (FTIR) of diesel fuel, biodiesel, and lemon essential oil bioadditive. The second step is the characterization of the physicochemical properties (density, viscosity, flash point, calorific value) of B20 biodiesel with various concentrations of lemon essential oil bioadditive, then compared with SNI 7182:2015. The third step is determining the rate of fuel consumption in diesel engines. The results show that Biodiesel B20 with a volume fraction of 2% lemon essential oil bioadditive has a high ability to reduce the rate of fuel consumption.

“…Clove oil is the essential oil composition of eugenol acting as the main component, two atoms of oxygen and can form a eugenyl acetate from the ester's reaction, thereby reducing fuel consumption and reducing exhaust emissions. Potential bio-additives based on clove and eugenol oils and about the influence of oxygen enrichment with eugenol can help achieve optimal fuel combustion [21]. The combined citrus oil and eucalyptus oils show the oxidation of stability above minimum standards.…”

Досліджено вплив застосування 4полюсного магнітного кола (NSNS) послідовно на горіння попередньо приготовленої суміші рослинного аро матичного масла при співвідношенні компонентів, що наближається до стехіометричного. Реакція реагенту призводить до того, що теплопередача характеризується підвищенням температури і має основну силу, яка об'єднує атоми металу завдяки цікавому тяжінню (NS) і (SN), що змушує елек трони вільно переміщатися завдяки енергії електро на. Взаємодія електронів викликає відділення атомів від реагентів з подальшим розпиленням і перенесен ням палива в краплю, а потім зіткнення в меншу краплю, більш гладку і ізольовану, утворюючи клі тинні АПІ. Результати дослідження показали, що магнітне поле підвищує інтенсивність реакції горін ня суміші, оскільки магнітне поле робить спін елек трона і протонного водню більш енергійним. Більш енергійні електрони і протони більш активно змі нюють структуру вуглецевих зв'язків в насичених і ненасичених жирних кислотах, як довголанцюгових, так і коротколанцюгових. Довголанцюгові насичені жирні кислоти і полярні форми більш активні, ніж коротколанцюгові і прямі, так як вони мають більш сильну полярність і більш вільний рух електронів. Введення магнітного поля підвищує реактивність вогню, швидкість, так як парамагнітний O 2 виділя ється більше через вогонь від Південного полюса (S) до Північного (N), в той час як тепло, що пере носиться H 2 O, який є діамагнітним, виділяється більше через вогонь з Північного полюса (N) на Пів денний (S). Це відбувається при зміщенні магніт ної котушки U і S. Отже, в зоні перемикання відбу вається утворення клітинного полум'я і зростання еквівалентності радіуса Ключові слова: рослинна олія, магнітне поле, співвідношення компонентів, тригліцериди, оптимі зація геометрії, напрямок магнітної лінії, біодобавки

“…The use of clove oil (as additive), neat orange oil, and orange oil–diesel blends, eucalyptus oil–diesel blends reduced CO, HC, and smoke emission. − Use of orange oil-increased nitrogen oxides (NO X ) emission can be attributed to having oxygen and the occurrence of higher heat release intensity during the premixed combustion phase. However, there are contradictory studies available that report orange oil as a nonoxygenated essential oil . Similar to orange oil, lemongrass oil and eucalyptus oil , also increased NO X emission.…”

Waste management cost for Australia is increasing every year, and thus, it is important to find alternative ways to use the waste. For example, essential oil has a significant waste stream that can be utilized in vehicles of their producers. However, some of the essential oils contain oxygen which considerably affects engine performance, emission, and combustion characteristics of diesel engines. Thus, this research paper will try to evaluate the essential oils as a replacement of diesel fuel to operate a multicylider diesel engine. For this study, two essential oils are selected which contain different oxygenated functional groups, tea tree oil (5.4% oxygen) and eucalyptus oil (8.4% oxygen), with an aim to evaluate the effect of these functional groups on engine performance and emission parameters. These oils were blended with neat diesel (0% oxygen) to obtain a blend cotaining 2.2% oxygen by weight. The blends produced similar brake power; however, brake-specific fuel consumption (BSFC) increased for eucalyptus oil blends (2.4–3.7%) and tea tree oil blends (3.9–5.3%). Essential oil–diesel blends resulted in less CO and increased NOX emission, produced similar peak pressure, and indicated mean effective pressure. The results then lead to the conclusion that oxygenated essential oils can have a role to reduce dependency of agricultural sector on diesel in the near future.
