EGR Venturi Vacuum Amplifier
EGR VENTURI VACUUM AMPLIFIER - Device which uses relatively weak venturi vacuum to control a manifold vacuum signal to operate the EGR
valve. Contains a check valve and relief valve which open whenever venturi vacuum signal is equal to or greater than manifold vacuum.
ELECTRONIC CONTROL ASSEMBLY (ECA) - A vehicle computer consisting of a calibration assembly containing the computer memory and thus its
control program and processor assembly, which is the computer hardware. The calibration assembly plugs into the processor. The processor plugs into
the vehicle harness. The ECA receives data from a number of sensors and other electronic components. Based on input data information programmed
into the ECA's memory, the ECA generates output signals to control various engine functions.
ELECTRONIC DISTRIBUTOR MODULATOR (EDM) - A distributor modulator which is electronically controlled and provides input to an ECA.
Electronic Engine Control
ELECTRONIC ENGINE CONTROL (EEC) - A computer directed system of engine control. EECI - control of engine timing. EEC-II - control of engine
timing and fuel (with FBC system). EECIII - FBC descendent of EEC-II. EEC-III - CFI control of engine timing and fuel (with EFI
system). EEC-IV is a descendent of the EEC-III with an FBC CFI and EFT control system.
ELECTRONIC SPARK CONTROL SYSTEM (ESC) - An electronic distributor vacuum control system aiding in more complete combustion through
controlled spark retard under certain temperature and speed conditions.
Engine Coolant Temperature Sensor
ENGINE COOLANT TEMPERATURE SENSOR (ECT) - Refers to thermistor sensor or its signal line. Sensor is immersed in engine coolant. Provides
engine coolant temperature information to ECU which is used to alter spark advance and EGR flow during warm-up or overheat conditions. (Replaces
cooling and EGR PVS.)
ENGINE RUNNING TEST - A section of the EEC-IV Self-Test that tests the inputs and controlled functions under actual operating conditions. The
actuators are exercised and checked for corresponding results.
EVAPORATIVE EMISSION CONTROLS (EEC) - Emission control system responsible for preventing fuel vapors from entering the atmosphere,
primarily from the fuel tank and carburetor.
