2. Oxygen sensor - Wikipedia

   en.wikipedia.org/wiki/Oxygen_sensor

   Using the O2 sensor signal, the ECU can operate the engine with an air–fuel ratio very close to 14.7:1, which is the ideal operating mixture for a three way catalyst to be effective. [3] Robert Bosch GmbH introduced the first automotive lambda sensor in 1976, [ 2 ] and it was first used by Volvo and Saab in that year.

4. Air–fuel ratio - Wikipedia

   en.wikipedia.org/wiki/Air–fuel_ratio

   Also called air–fuel ratio gauge, air–fuel meter, or air–fuel gauge, it reads the voltage output of an oxygen sensor, sometimes also called AFR sensor or lambda sensor. The original narrow-band oxygen sensors became factory installed standard in the late 1970s and early 1980s. In recent years a newer and much more accurate wide-band ...

6. Lean-burn - Wikipedia

   en.wikipedia.org/wiki/Lean-burn

   The heart of the Mitsubishi's MVV system is the linear air–fuel ratio exhaust gas oxygen sensor. Compared with standard oxygen sensors, which essentially are on-off switches set to a single air/fuel ratio, the lean oxygen sensor is more of a measurement device covering the air/fuel ratio range from about 15:1 to 26:1.
