Alternativas que reduzam a dependência da matriz energética mundial aos derivados do petróleo são discutidas cada vez mais. Existe uma grande quantidade de dados acadêmicos relacionando consequências perniciosas ao meio ambiente devido a indústria de petróleo e seus componentes refinados. A substituição dos óleos a base mineral pela base vegetal é uma medida seguindo essa tendência. O óleo vegetal é uma substância biodegradável com a capacidade comprovada de ser decomposta em um intervalo de até um ano, o que faz com que seja um produto menos tóxico e agressivo ao meio ambiente do que os de base minerais. O óleo vegetal escolhido para esse trabalho foi o de dendê, por ser um óleo popularmente conhecido na culinária brasileira, principalmente baiana. É um dos óleos vegetais mais consumidos no mundo, atrás apenas dos óleos de soja e canola. O objetivo desse estudo foi comparar as propriedades e comportamentos do óleo mineral 15w-40 com o óleo de dendê através de um ensaio PIN-ON-DISK com presença do filme de óleo. Após os ensaios, os óleos utilizados foram analisados através dos dados de espectrometria, ferrografia, viscosidade de Saybolt, monitor de partículas ferrosas e dos sinais coletados pelo software, gerados pelo tribômetro. Pelos resultados obtidos, observou-se que o lubrificante vegetal, óleo de dendê, tem grande potencial para ser usado na substituição do óleo mineral. Os dados apresentaram a real possibilidade da utilização do óleo livre de qualquer tipo de tratamento adicional a fim de torná-lo mais eficiente, como mistura de aditivos ou envelhecimento.Palavras-chave: Tribologia.

Desgaste.Viability analysis of the use of dende oil in automotive lubrication through the pin-on-disk testAbstractAlternatives that reduce the dependence of the world energy resources on mineral oil derivatives are increasingly discussed. There is a great deal of academic data relating pernicious consequences to the environment due to the oil industry and its refined components. The substitution of mineral based oils for the vegetable base is a measure following this trend. Vegetable oil is a biodegradable substance with a proven ability to decompose within an interval up to one year, making it a less toxic and environmentally aggressive product than mineral based ones. The vegetable oil chosen for this study is extracted from the palm tree (Elaeisguineenses). This oil is popularly known in Brazilian cuisine, mainly in Bahia. It is one of the most consumed vegetable oils in the world, soy and canola oils are in the upper positions. The objective of this study was to compare the properties and behaviors of 15w-40 mineral oil against palm oil through a PIN-ON-DISK test with presence of the oil film. After the tests, the oil used was analyzed using spectrometric, ferrography, Saybolt's viscosity, ferrous debris monitor data and signals from the tribometer collected by the software. From the results obtained, it was observed that the palm oil lubricant has great potential to replace mineral oil. The data showed the real possibility of using palm oil without any additional treatment in order to make it more efficient, such as mixture of additives or artificial aging.Keywords: Tribology.

Vegetable oil has been investigated to displace products which are derived frompetroleum because of its environmentally-safe properties and has become a vital source forbio-lubricants. Vegetable oil availability as one of the renewable sources is one of theusefulness of it. Additionally, the vegetable oils based lubricant has indicated the potentialsfor reducing carbon dioxide and hydrocarbon emission while operating in internalcombustion engines and in industrial processes. In this study, the mustard seeds oil wasinvestigated to study its lubricant characteristics under different loads while comparing itwith commercial lubricant using a pin-on-disk tribometer. The whole experiential workswere corresponding to American Society for Testing and Materials (ASTM G99).Under lowload, the results exhibit that the mustard seeds oil shows adequate tribological characteristicscompared to other petroleum oil samples. In conclusion, the mustard seeds oil has a betterwear and friction resistance. Therefore, mustard seeds oil can be used for lubrication ofmating components.

The article is devoted to the issues of placing seed production in the conditions of world export of vegetable oils. In 2019, the volume of Russian exports of sunflower oil exceeded 3 million tons for a total of $ 2,2 billion, which is about 30% of the vegetable oil produced in the country. In Russia, the main oilseeds are sunflower, rapeseed, and soy. Less common crops include oilseed flax, ginger, mustard, and safflower. It is stated that in 2001–2019, the acreage of all types of oilseeds in the country increased by more than 2 times, and the gross harvest – by 3,3 times, while the yield increased by 1,4 times.
