Glossary “electrostatic shield” Definition:
Shielding that protects a device or circuit from electrostatic energy, but not necessarily from electromagnetic energy.
e
electrostatic spray gun
Glossary “electrostatic spray gun” Definition:
Electrically charges the paint particles at the gun to attact them to the vehicle body.
element
Glossary “element” Definition:
Substance that cannot be further divided; the smallest partials of pure matter.
electronic refrigerant leak detector
Glossary “electronic refrigerant leak detector” Definition:
Provides a safe and accurate method of locating refrigerant leaks. It can be adjusted to compensate for background refrigerant contamination. It emits a clicking/beeping tone which increases in speed as the detector senses concentrated refrigerant leakage.
electronic spark control (ESC)
Glossary “electronic spark control (ESC)” Definition:
System that controls and governs the vacuum signal to the distributor to assure proper distributor retard/advance under various engine load conditions.
electronic spark timing (EST)
Glossary “electronic spark timing (EST)” Definition:
Electronic system that, based on input signals, provides the correct spark timing for a given engine condition.
electronic vibration analyzer (EVA)
Glossary “electronic vibration analyzer (EVA)” Definition:
Electronic tool that senses and displays vibration frequencies and amplitudes.
electroplating
Glossary “electroplating” Definition:
A process for depositing metal on a conductive surface that is made by the cathode in an electrolytic bath containing dissolved salts of the metal being deposited.
electrostatic
Glossary “electrostatic” Definition:
A kind of electricity where the charges are not moving.
electronic leak detector
Glossary “electronic leak detector” Definition:
AC or DC powered leak detector that emits an audible and/or visual signal when its sensor is passed near a refrigerant leak.
electronic level control (ELC)
Glossary “electronic level control (ELC)” Definition:
Device that automatically regulates the ride height of a vehicle under various load conditions.
electronic distributorless ignition system (EDIS)
Glossary “electronic distributorless ignition system (EDIS)” Definition:
Electronic ignition system that relies on a computer to time and route the electrical spark to the proper spark plug at the proper interval. Now known as electronic ignition (EI) system.
electronic engine control (EEC)
Glossary “electronic engine control (EEC)” Definition:
System that regulates the engine management functions.
electronic feedback carburetor (EFC)
Glossary “electronic feedback carburetor (EFC)” Definition:
Carburetor that controls the air/fuel mixture according to commands from the engine control computer.
electronic fuel control (EFC)
Glossary “electronic fuel control (EFC)” Definition:
Fuel system that used electronic devices to monitor engine functions to ensure that the proper air/fuel ratio reaches the combustion chamber for optimum engine performance under any operating condition.
electronic fuel-injection system
Glossary “electronic fuel-injection system” Definition:
Fuel injection system that injects gasoline into a spark-ignition engine that includes an electronic control to time and meter the fuel flow.
electronic ignition (EI)
Glossary “electronic ignition (EI)” Definition:
An ignition system where a solid state device has replaced mechanical breaker points.
Electronic Ignition System
Glossary “Electronic Ignition System” Definition:
1). Ignition system that is controlled electronically rather than by mechanical methods. 2). An ignition system controlled by the use of sensors and or signals. 3). J-1930 acronym that indicates that all ignition systems that do not use a distributor are called electronic ignition (EI) systems, while those with distributers will be called distributor ignition (DI) systems whether they have electronic components or points.
electronic control unit (ECU)
Glossary “electronic control unit (ECU)” Definition:
Digital computer that controls engine and transmission functions based on data that it receives from sensors, relative to engine rpm and temperature, air temperature, intake manifold vacuum, exhaust oxygen content and throttle position.
electronic controlled ignition (ECI)
Glossary “electronic controlled ignition (ECI)” Definition:
Term that often applies to an EI system.
