The use of renewable basestock lubricant containing metal-free additive and their effects on triboproperties and diesel engine CO2 emission

Abstract

In every IC engine, there will be a certain amount of unburned fuel that passes through piston rings and enters the lubricating oil that affects lubricant degradation trough reactions with chemical species and will cause greater wear in the engine as well as influencing the combustion efficiency indefinitely. Renewable based-lubricant with the presence of non-metallic additive reduce wear rate. There is a significant material weight loss and lower friction coefficient. The renewable based lube oil with additive also succeeds in reducing CO2 emission ∼ 5% compared to the mineral based. This is an abstract of a paper presented at the 2009 World Tribology Congress (Kyoto, Japan 9/6-11/2009).
