Effect of Ethanol-Gasoline Blends on MPFI Engine Performance, Emission and Lubricating oil Properties

K B Siddegowda, J Venkatesh

Experimental investigation has been carried out on MPFI engine to study the effects of gasoline-ethanol blends on lubricating properties. For any four stroke engine the function of engine lubricants play an important role since the lubricants does not burn along with fuel in the combustion chamber as two stroke engine. The lubricant will circulate around inside the engine and its quality decreased time b y time. Basically the functions of engine lubricants are prevent wear from friction and keep the engine cool. The performance of engine lubricants is to reduce friction, oxidation, minimize deposit formation and prevent corrosion and wear. In this experimental study of gasoline and gasoline-ethanol blends like 10, 20, 30, by volume compared with results gasoline and gasoline ethanol blends. The lubricating properties examined in the assessment work lubricating capacity, viscosity, stability of oxidation, foaming charactes, carbon residue and flash point , kinematic viscosity and iron content are lower than gasoline run engine can be effectively used with E20. The lubricating properties are examined by AAS and IS standards.
