Walker Oxygen Sensors are precision made for outstanding performance and manufactured to meet and exceed all original equipment specification and test requirements.
Located in the exhaust system, the oxygen sensor produces a voltage proportional to the amount of oxygen in the exhaust versus the air (<150 mV lean & >750 mV rich). This data is used to control the air-fuel mixture through PORT or TFI injectors and carburetors. Sensors are monitored or checked anywhere from 4 to 100 times per second. The air-fuel mixture is thus always moving from rich to lean averaging very close to stoichiometric (ideal) ratios.
The oxygen sensor, often referred to as the O2 sensor, plays a crucial role in monitoring the oxygen content in the exhaust gas. As you mentioned, it generates a voltage signal that is proportional to the oxygen concentration. This information is utilized by the engine control unit (ECU) to continuously adjust and maintain the air-fuel mixture at an optimal level for combustion efficiency.
The voltage signal from the oxygen sensor indicates whether the mixture is rich (high voltage) or lean (low voltage). Based on this feedback, the ECU adjusts the fuel injection or carburation to achieve a balance close to the stoichiometric ratio, the ideal proportion of air to fuel for complete combustion.
The frequency at which these adjustments occur is quite rapid, with sensors being checked multiple times per second. This constant monitoring and fine-tuning help ensure that the engine operates as efficiently as possible, minimizing emissions while optimizing performance and fuel economy.
