The only analog sensor in the system was the oxygen sensor. In other respects, it was a typical "feedback" carburetor system of the early-1980s, using a stepper motor to control fuel mixture and a two-stage "Sole-Vac" (which used a solenoid for one stage, and a vacuum motor for the other) to control idle speed.

An onboard refueling vapor recovery system (ORVR) is a vehicle fuel vapor emission control system that captures volatile organic compounds (VOC, potentially harmful vapors) during refueling. [ 1 ] [ page needed ] There are two types of vehicle fuel vapor emission control systems: the ORVR, and the Stage II vapor recovery system. [ 2 ]
Renix Electronique S.A. was established in 1981 as a joint venture by Renault with 51% interest and Bendix with 49% that was headquartered in Toulouse. [1] Renix Corporation of America was the North American subsidiary of Renix Electronique to provide sales, logistics, engineering, and quality support to American Motors.
An engine control unit (ECU), also called an engine control module (ECM), [1] is a device that controls various subsystems of an internal combustion engine. Systems commonly controlled by an ECU include the fuel injection and ignition systems.
Cadillac fuel-injected vehicles are equipped with actual onboard diagnostics, providing trouble codes, actuator tests and sensor data through the new digital Electronic Climate Control display. Holding down 'Off' and 'Warmer' for several seconds activates the diagnostic mode without the need for an external scan tool.
If the electrical part of the control should fail, an EEC will revert to a standard hydromechanical fuel control. Full-authority digital engine control (FADEC): A digital computer which controls a servo-operated fuel valve. In this case the power lever is only electrically connected to the fuel control.
Gas nozzle with vapor recovery Vapor (or vapour ) recovery is the process of collecting the vapors of gasoline and other fuels, so that they do not escape into the atmosphere. This is often done (and sometimes required by law) at filling stations , to reduce noxious and potentially explosive fumes and pollution.
The sending unit usually uses a float connected to a potentiometer, typically printed ink design in a modern automobile. As the tank empties, the float drops and slides a moving contact along the resistor, increasing its resistance. [2] In addition, when the resistance is at a certain point, it will also turn on a "low fuel" light on some ...
