Viscosity Index Improver for Engine Oils: An Experimental Study
Engine oils are widely used for lubrication purposes in automobile and related industries. Viscosity Index (VI) improver has found its largest commercial applications as additives to engine oils. Examples are power steering fluid, aircraft piston engine oils, modern internal-combustion engines, turbine engine oils (stationary and aircraft), and industrial gear oils. Viscosity Index improvers ar...
متن کاملInvestigation of shear stability of commercial polymer of viscosity index improver for determination of engine oil optimal formulation
The lubricating oils in each mechanical device are affected by shear forces. Polymers in lubricating oils engine, in particular, undergo many changes because of the influence of the applied forces. Awareness of these changes can help us to design optimal formulations. In this work, shear stability of four commercial was studied. Calculation of various parameters about viscosity in the enhancing...
متن کاملAgriculture’s Contribution to Hawaii’s Economy
There is much debate on the size and importance of agriculture in Hawaii’s economy. Estimates of agriculture’s contributions vary significantly, depending on what is defined as “agriculture” and on the methodol ogy used to develop those estimates.

متن کاملThe Contribution of Agriculture to Economic and Productivity Growth of Iranian Economy
The historical experience of many developing countries show that many developing world has not paid enough attention and is not giving serious thought to its agricultural sector. In fact, nearly all the countries that have “undervalued” their agricultural sectors not only failed to grow rapidly, but they all encountered domestic food shortages, balance of payment crisis and some sort of politic...
متن کاملGlobal Fuel Economy Initiative
The critical distinction between the technical potential to improve fuel economy and how much of that technical potential is realized .. Summary The Global Fuel Economy Initiative was launched in early 2009. It set a target of improving the average fuel economy (in litre/100km terms) for the global vehicle light-duty vehicle fleet by at least 50% by 2050 (50by50). In terms of miles per gallon t...
