摘要

With the introduction of various mandates to reduce CO_2 emissions around the world, emphasis on reduced fuel consumption has increased. Improvements in engine design such as surface modification, use of coatings, advancement in the combustion chamber design, and improved fuel qualities are some of the approaches used to reduce fuel consumption. On the other hand, emphasis to reduce friction in the piston liner/ring interface, valve train and bearings has also increased through the use of low viscosity engine oils and durable friction modifiers. In this study, friction reduction and friction retention properties of various organometallic and organic friction modifiers in low viscosity engine oils have been investigated. It is well known that molybdenum dithiocarbamates (MoDTC's) provide superior friction reduction performance to improve fuel economy. Recent work suggests that subtle changes in MoDTC chemistry can have a large impact on frictional reduction properties at low molybdenum treat levels in the finished engine oil. Research has been carried out to optimize friction reduction capabilities of MoDTC technology when used in combination with organic friction modifiers in low viscosity oils as a means of achieving further advances in fuel economy. In this study the effect of frictional properties and film formation properties of various MoDTC's alone and in combination with organic friction modifiers was measured using the Mini Traction Machine. The influence of concentration, temperature and rubbing time on the frictional properties was investigated.
