Elky

The Chevrolet El Camino.

Elliot Axle

A solid-bar front axle on which the ends span the steering knuckle.

Elliptical Spring

A term used for leaf spring.

Elongation

The stretching of a material.

Embedability

The ability of a bearing to permit small dirt particles to sink into the bearing surface, thereby avoiding certain crankshaft scratches.

Embossed Gasket

A shim-type head gasket having a raised surface.

Embrittlement

A condition whereby a part becomes hard and brittle due to excessive flexing.

EMC

Electro-magnetic compatibility.

EMCC

Electronically Modulated Converter Clutch (Chrysler ).

Emergency Brake System

A brake system used for stopping a vehicle in the event of a malfunction in the means of operation and control of the service brake system.

Emery Paper

An abrasive-coated paper used for fine finishing. Also called emery cloth.

EMF

Electro-motive force.

EMI

Electro-magnetic interference "NOISE".

Emission

(electrical) The release of free electrons from the surface or a material.

Emission Standards

The federal-government-established emission and pollutant standards for all motor vehicles because of environmental damage in the part.

Emissions

Unwanted, harmful chemicals and chemical compounds that are released into the atmosphere from a vehicle, especially from the tailpipe, crankcase, and fuel tank including unburned hydrocarbons, carbon monoxides of nitrogen, particulates, and sulfur.

Emissions

The exhaust that comes out of a vehicle's tailpipe or tailpipes. Harmful emissions are reduced on most newer vehicles (except diesels) through the use of a catalytic converter. Cats are designed to reduce the amount of hydrocarbons (HC), carbon monoxide (CO) and oxides of nitrogen (NOx) that exit a vehicle and are therefore vented into the atmosphere. Other kinds of pollution-reduction devices have been used on cars and trucks over the years, including a positive crankcase vent valve, a charcoal canister and an air injection reactor pump.

Emissions Control

A term used for emission controls.

Emissions Warranty

A federally mandated 5-year/50,000 mile performance and defect warranty that covers all emissions-related components on all new vehicles built since 1982. In 1995 the emissions warranty was reduced to 2 years/24,000 miles on all emissions-related components except the computer and catalytic converter, which are extended to 8 years/80,000 miles.

Emitter

The semiconductor material in a transistor that emits carriers into the base region when the emitter base junction is forward biased.
