- Emergency:
- A sudden,
unexpected occurrence, such as a breakdown or the failure of some part, which may be dangerous
and demands immediate action.
- Emergency brake:
- A
braking system which is independent of the main
hydraulic system. It can be used to slow or stop the vehicle
if the primary brakes fail, or to hold the vehicle stationary though the
brake pedal is not depressed. It usually consists of a foot

cables and linkages. It is also called the "
parking brake" or E-brake.

- An aerosol can which inflates a punctured tire and injects sealing compound to
provide at least a temporary repair
- Emergency
transmitter:

windshield:
- A sheet of clear plastic fitted in place of a broken windshield
- Emery cloth:
- A cloth coated in
emery crystals like fine sandpaper for use as an abrasive on metals
- EMF:
- Acronym for "electromotive force"See:
voltage.
- Emily:
- An affectionate name for the
RollsRoyce radiator mascot, the "Spirit of Ecstasy"

- Emission control:
- A
system for restricting the amount of noxious emissions. There are two standards for emission
controls: level E for Europe and the more stringent level U for the United States.

- Emitter:

- Employment:
- Total
employment in each manufacturing facility, including total manufacturing employees, total
support staff, and total engineering/R&D staff. Average number of workers employed by an
establishment during the year. Production workers relate to the average number actually engaged
in the manufacturing process. Administrative and non-manufacturing includes employees at head
offices and sales offices.
- Employee
benefits:
- The provision of direct (salary, bonuses, etc.) indirect (vacation leave, medical
and dental plans, etc.) and deferred employee compensation (pensions, etc.).
- EMS:
- Acronym for Engine Management System
- Emulsification:
- The
process of making an emulsion
- Emulsion:
- A mixture of two liquids
which do not fully mix, such as oil and water, or specifically of gasoline and air in a carburetor
before it is discharged and fully atomized
- Emulsion tube:
- Part of a
fixed jet carburetor, in which air is introduced into the mixture through holes to help atomize it
and correct excessive richness at higher engine speeds. A perforated tube which extends from an
air bleed in the top of the air horn down into the main well. Admits air from the air bleed into the
main well to emulsify the fuel in the main well. Improves idle response and stability when the
engine is hot and prevents fuel percolation and general hot-starting problems. Also improves
response in the main metering circuit during part throttle conditions. Also called
main-well tube
