Summary on Grant Application Form
The main driving forces in the development of new automotive technology are fuel economy, emissions and NVH (noise, vibration and harshness); the first two being government mandated. In the lifetime of a heavy duty vehicle, up to 70% of the costs incurred can be fuel-related. The desire to reduce running costs therefore translates to a need to minimise friction. The overall goal in the operation of vehicles is therefore to achieve longer drain intervals and this can only be achieved by the development of even more efficient lubricants. The increasingly stringent legislation at a national and European level will ensure that measures are taken to minimise particulate and gaseous emissions. This involves improvements in lubricant technology to improve wear protection in engines beyond what is currently obtainable. The current position is that in order to achieve the substantial improvements in the anti-wear and friction reducing performance required by legislation and by economics, there must be an integration of surface science and tribology. This proposal addresses the tribological and tribochemical processes occurring in a specific oil/additive system comprising the anti-wear additive ZDDP and the friction reducing additive MoDTC.
