Oxygen Sensor: Description and Operation
Fig. 10 Oxygen (Lambda) Sensor
An oxygen (Lambda) sensor, is used to provide more precise control of air/fuel mixtures. This system operates by measuring oxygen content in
exhaust gases, as the amount of oxygen remaining in the exhaust gases is directly proportional to the air/fuel ratio of mixtures entering the engine. The
sensor, mounted in the exhaust stream, reacts to the oxygen remaining in the exhaust gases and produces a variable voltage signal (0-1.0 vdc) depending
upon the oxygen content.
