E.G.R. (Exhaust Gas Recirculation) Valve Engine Parts

System to reduce automotive emission of nitrogen oxides (NOx). It routes exhaust gases into the intake manifold where they dilute the air/fuel mixture and reduce peak combustion temperatures, thereby reducing the tendency for NOx to form.

Elastohydrodynamic Lubrication (EHD or EHL) Properties

Lubrication characterized by high unit loads and high speeds in rolling elements where the mating parts deform elastically due to the incompressibility of the lubricant film under very high pressure.

Elastomer Chemicals

A rubbery type of material.

EMA Industry Associations

Engine Manufacturers Association

Emissions Engine Performance

Term used generically to refer to the various components of the engines exhaust.

Emulsifier Chemicals

Substance used to promote or aid the formation of a stable mixture, or emulsion of oil & water.

Emulsion Chemicals

Mixture of two liquids, which are not soluble with each other, such as oil and water.

Engine Deposits Engine Performance

Hard or persistent accumulation of sludge, varnish and carbonaceous residues due to blow-by of unburned and partially burned fuel, or the partial breakdown of the crankcase lubricant. Water from the condensation of combustion products, glycol, carbon, res

Entrainment Properties

Describing a state of an immiscible fluid component. Minute quantities of a fluid (typically water) can be dissolved or absorbed into the oil, but excess quantities can be most harmful to equipment due to the entrainment leaving gaps in the lubricated are

EP (Extreme Pressure) Lubricants Chemicals

Lubricants that impart to rubbing surfaces the ability of carrying greater loads than would be possible with ordinary lubricants without excessive wear or damage.

EP additive Chemicals

A lubricant additive that prevents sliding metal surfaces from seizing under conditions of extreme pressure (EP). At the high local temperatures associated with metal-to-metal contact, an EP additive combines chemically with the metal to form a surface fi

Erosion Properties

The wearing away of a surface by an impinging fluid or solid

Ester Chemicals

An organic compound formed by the reaction of an acid (organic or inorganic) with an alcohol.

Ethanol Chemicals

Ethyl alcohol mainly formed through fermentation. (Alcoholic drinks, component in gasohol)

Ethylene Glycol Chemicals

A colourless, syrupy liquid, used as an antifreeze in cooling and heating systems.

Evaporation Loss Properties

The loss of a portion of a lubricant due to volatization.
