lubricant Viscosity and Viscosity Improver additive effects on diesel fuel economy
Tribology International, 2010Co-Authors: Margareth Judith Souza De Carvalho, Peter Rudolf Seidl, Carlos Rodrigues Pereira Belchior, Jose Ricardo SodreAbstract:Abstract This work verifies the impact of lubricant Viscosity and Viscosity Improver additives on diesel fuel economy. Eight lubricants were tested in a single-cylinder, four-stroke, direct injection diesel engine mounted on a dynamometer, under different load and speed conditions. Engine friction power was also investigated through Willans’ line. The results demonstrate that fuel economy obtained from multigrade Viscosity oils is higher than that obtained from monograde Viscosity oils. A linear relationship was obtained between the high temperature high shear Viscosity and specific fuel consumption. The lubricant which provided lower fuel consumption also required lower friction power.

performance of polymeric Viscosity Improver as bio lubricant additives
International Journal of Structural Integrity, 2019Co-Authors: Muhammad Arif Dandan, Syahrullail Samion, Nurul Farhanah Azman, Fazila Mohd Zawawi, Mohd Kameil Abdul Hamid, Mohamad Nor MusaAbstract:The purpose of this paper is to study the influence of polymeric Viscosity Improver on the tribological performance of palm kernel methyl ester (PKME).,Tribological performances of the PKME added with the various concentration of ethylene-vinyl acetate copolymer (EVA) were evaluated using four-ball tribotester under extreme pressure condition. The morphologies of the worn surfaces were observed by using the optical microscope.,The addition of polymeric Viscosity Improver (EVA copolymer) has produced positive results towards the tribological properties of PKME. In total, 4 per cent of EVA copolymer is found as the optimum concentration by improving the friction reducing properties and anti-wear behaviour due to the formation of film thickness between two rubbing surfaces.,This work might contribute to the development of vegetable oils as a new source of environmental-friendly lubricant.
