DELPHI - ES20000 - Oxygen Sensor

Delphi oxygen sensors measure the amount of oxygen in the exhaust and are also known as lambda sensors. Oxygen sensors are one of the most important components of the vehicle that help in maintaining a harmonious balance between air and fuel for reduced emissions. Too much fuel or a rich mixture produces hydrocarbons and carbon monoxide as emissions and too lean mixture or more oxygen emits more nitrogen-oxide pollutants. Delphi Technologies oxygen sensors maintain this air-fuel mixture precisely because they incorporate proven OE technology for fast-acting, long-lasting performance.

The major emissions including hydrocarbons and carbon monoxide are released as the vehicle cold starts. Therefore, a fast-acting oxygen sensor becomes important and our planar sensor element with integrated heater reaches optimum operating temperatures quickly. This allows for a quicker closed-loop activation and reduced cold-start emissions. Delphi Technologies planar oxygen sensors have the fastest activation time and offer three times more planar coverage than their closest competitor.
