Emission and Tribological Studies on Nano CuO/Jatropha Methyl Ester/Synthetic Mineral Oil in a Two-Stroke Engine

Bannari Amman Institute of Technology-Anbalagan Ramakrishnan
Vellore Institute of Technology-Govindasamy Rajamurugan, Prabu Krishnasamy
Published 2019-10-11 by SAE International in United States
In lieu of the drastic growth of the vehicle population, there is a huge consumption of fossil fuels and mineral oils for mobility. This leads to depletion in fossil fuels and mineral oils which are the by-products of petroleum. These fossil fuels can’t sustain for a long period of time because of its toxicity. In order to reduce the usage of existing mineral oil for lubrication, a source of non-edible oil from Jatropha curcus is processed as jatropha methyl ester (JME). It is holding high viscosity, density and easy blend with base oil. In this current work, the wear resistance of the lubricating oil is enhanced by the addition of nano-copper oxide particle blend with the base oil. The emission performance and tribological behavior have been experimentally tested in 98.2CC two-stroke air cooled engine. The 20% of JME blend with CuO nano particle provides better emission performance and wear characteristics than the other combination of blends.

Synthesizing Renewable Oils for Use in Lubricants

  • Magazine Article
  • TBMG-34138
Published 2019-04-01 by Tech Briefs Media Group in United States

Industrial machinery, agricultural equipment, transportation vessels, and home applications depend on lubricants; however, they leave a heavy environmental footprint. Common lubricants, oils, greases, and emollients typically consist of mineral, or petroleum, base oils — often up to 90 percent by weight. These mineral base oils are highly volatile and tend to thicken quickly, which means that lubricants need to be replaced often, generating waste.

Evaluation of Gas Turbine Engine Lubricant Compatibility with Elastomer Slabs - Long Duration Test

E-34 Propulsion Lubricants Committee
  • Aerospace Standard
  • ARP6917
  • Current
Published 2018-12-10 by SAE International in United States
This test method provides procedures for exposing specimens of elastomer material (slab form) representative to those used in gas turbine engines to aviation lubricants under extended duration and engine relevant thermal conditions. For AS5780 requirements the time is at least 1800 hours and temperatures are 100 °C to 160 °C. Positive volume change is an indication of specimen swell and subsequent negative volume change is an indication of specimen deterioration, both properties are important in the evaluation of the compatibility of the lubricant with elastomers used in the construction of the gas turbine.

Storage of Elastomer Seals and Seal Assemblies Which Include an Elastomer Element Prior to Hardware Assembly

A-6C2 Seals Committee

  • ARP5316E
  • Current
Published 2018-10-30 by SAE International in United States
This SAE Aerospace Recommended Practice (ARP) addresses the general requirements for data recording procedures, packaging, and storing of elastomeric seals and seal assemblies which include an elastomeric element prior to the seal being assembled into hardware components. It applies specifically to those elastomeric seals and seal assemblies packaged shortly after manufacture. The storage period prior to installation of the elastomeric seals and seal assemblies into hardware components is commonly referred to as shelf life. The information contained in this ARP is intended to be utilized by those organizations who do not have specific requirements or recommendations already in place for the control of elastomeric seals and seal assemblies. This ARP can be specified in control, storage, and procurement documents. However, when the requirements of this document are in conflict with the customer's requirements or specifications, the requirements of the customer's detailed specification shall govern.

This index provides an overview of lubricants and symbols for the purpose of assisting the user in the identification of the appropriate product and relevant SAE specification. The aim is to better determine the best lubricant to be used for a particular application. If containers used for shipping lubricants are also to be marked, the same identification and symbols should be used. See also ISO 5169 Machine tools - Presentation of lubrication instructions.
