Electrolyte
Any solution that conducts an electrical current, such as a mixture
of sulfuric acid and distilled water found in automotive batteries.
Electronic Fuel Injection
System
A system that injects fuel into the engine and includes an electronic
control unit to time and meter the fuel flow.
Electronic Ignition
System
An ignition system that uses transistors and other semiconductor
devices as an electronic switch to turn the primary current on and
off.
EPA Fuel Economy Rating
Comparative mileage figures generated from laboratory fuel-economy
tests administered by the federal Environmental Protection Agency
(EPA) using simulated weight and drag to approximate real driving
conditions.
Exhaust-Gas Recirculation
(EGR)
An exhaust-emission control system in which a portion of the exhaust
gas is picked up from the exhaust manifold and sent back to the
intake manifold t be reburned in the engine. Mixing exhaust gases
with the fresh air/fuel mixture lowers the combustion temperature
and reduces the formation of oxides of nitrogen in the exhaust.
Exhaust Manifold
The network of passages that gathers the exhaust gases from the
various exhaust ports and routes them toward the catalyst, the muffler
and the exhaust system.
