Efficiency (energy)

Energy conversion efficiency is the ratio between the useful output of an energy conversion machine and the input, in energy terms. The useful output may be electric power, mechanical work, or heat.

Efficient

To produce work without wasting time and energy.

Effort

A force or action that tries to achieve something.

EFI

Electronic fuel injection using sensors, an electronic control unit and fuel injectors to spray fuel into a central throttle body or the inlet ports. Provides very close control of fuel mixture under all operating conditions.

EGO

Exhaust Gas Oxygen Sensor. Also HEGO - Heated Exhaust Gas Oxygen Sensor, EOS Exhaust Oxygen Sensor and Lambda sensor. Provides information to the fuel system ECU on the oxygen content in the exhaust gas.

EGR

Exhaust gas recirculation. An emission control system that uses an exhaust gas feed into the intake air stream to reduce the mass of oxygen in the air charge and limit the formation of harmful oxides.

EGRPS

EGR Valve Position Sensor

EGRT

EGR Temperature

EI

Electronic Ignition

Elastic Limit

Amount of deflection in a spring that can be tolerated before permanent deformation occurs.
