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 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 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 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.
