Shell Lubricants Believes Lubricants be considered a design component.
Taking time upfront to specify a lubricant and ensure its compatibility with other materials pays off in the long run. Lubricant and material suppliers can offer compatibility guidance, but only component testing can provide real assurance. Why? A single category of elastomer, Nitrile, for example, can have as many as 100 possible formulations, each with different compatibility issues. So it is virtually impossible to make accurate, all-inclusive compatibility recommendations without actually testing a lubricant on a material.
When testing compatibility, materials should be exposed to lubricants under various temperatures, speeds and loads. For the most accurate evaluation of lubricant/material compatibility, test at the expected operating extremes. For further assurance, test materials of nearby components in case of oil migration or outgassing and condensation.
Shell Lubricants recognises this shortcoming and advices.
Shell Lubricants’s Simon Warburton says its lubricants should be viewed in the same light as the most essential component with its input aiding the drive for ever-greater fuel efficiency. The energy supplier made the comments at the Shell Technology Centre in Hamburg, where it showcased its Project M collaboration with The Gordon Murray Design Group and engine specialist, Geo Technology to improve fuel burn and powertrain efficiency.
Affordable is key – you want it to be low priced – not only to the Western world but to emerging economies as well. Our [view] in Shell is internal combustion engines will still form a significant part of transport to 2050 and beyond.”
Shell is providing the fluids for the car specifically ‘designing’ the motor oil to enhance overall efficiency.
The energy producer notes it would be a normal assumption that oil, greases and fuels are added at the end of a concept-car build project such as the T25S, but Project M Shell aims to show what can be achieved when its products are integrated into the design, right from the start.
