Alternative methods for automotive industry to decrease friction without reducing viscosity

Millers Oils : 02 December, 2013  (Technical Article)
At a recent conference in Brussels, specialist oil developer and producer Millers Oils warned of the dangers of relying upon simply reducing oil viscosity to help meet increasingly stringent emissions targets. Concurrent oil and driveline development can optimise the efficiency of current technologies, and enable the evolution of a new generation of low emissions vehicles that benefit from increased durability and reliability.
Alternative methods for automotive industry to decrease friction without reducing viscosity
“Innovative oil development is able to solve a number of problems currently posed by recent trends in drivetrain advancement,” says Martyn Mann, Millers Oils Technical Director. “Compatibility with changing, sensitive emissions technologies, smaller sump capacity, fewer and smaller crank bearings, high specific power output and increased low speed torque loads are just some of the areas that traditional oils struggle to address efficiently. The expectation of increased service intervals, hybrid drives and aggressive thermal environments necessitates thorough lubrication development, and manufacturers must resist the temptation of reducing oil viscosity.” 
 
The broad challenge faced by oil developers is to reduce friction while increasing durability, as downsized engines and alternative powertrains place increasing strain on traditional lubricants. Millers Oils’ new Nanodrive range utilises nanotechnology to address these concerns by increasing film strength of the oil, reducing parasitic losses to improve power and torque while reducing fuel consumption. 
 
“Twenty per cent of an engine’s CO2 emissions arise through friction, and more energy is lost through friction than is delivered to the wheels,” says Nevil Hall, Millers Oils Joint Managing Director. “The important focus is to ensure that oil technology is carefully considered as vehicle manufacturers continue to develop efficient drivetrains. Advanced lubrication technology can not only support the work of OEMs to deliver reliable downsized engines and alternative powertrain, but optimise the potential gains of these continually developing technologies.”
