Delphi Switching Oxygen Sensors Delphi Switching Oxygen Sensors with planar element technology provide stoichiometric measurement of exhaust gases for gasoline and alternative fuel engine applications to help manufacturers meet current and future emissions standards. Delphi Switching Oxygen Sensors include a pumped air reference feature to prevent air reference contamination. They can be used in the engine-out position and in a post-converter location for more accurate engine control and for better exhaust system diagnostics. Fast light-off time with a low-wattage heater can help reduce system costs, help reduce cold-start emissions, and help eliminate the need for other emissions devices. Pumped air reference prevents air reference contamination. Industry-leading poison-resistant coating helps improve sensor durability. High temperature resistance allows sensor location flexibility and consistent operation across a wide range of temperatures, including high engine temperatures. It also helps provide improved sensor reliability and durability. Low power consumption reduces the vehicle's electrical energy requirements. Robust construction resists thermal shock without cracking. Demonstrated production flex fuel capability. Delphi offers Switching Oxygen Sensors with both "breathable" and "non-breathable" membranes to suit a variety of customer needs. Typical Applications Delphi's Switching Oxygen Sensors can be used for passenger vehicle and commercial vehicle gasoline and alternative fuel applications (including ethanol blends E0 to E100) to help vehicle manufacturers meet current and future emissions regulations. They can also be used for motorcycles and other small engine applications. Performance Advantages Delphi's Switching Oxygen Sensors offer cost and performance advantages versus conventional conical sensors including faster light-off time and a low-wattage heater. They can also help achieve lower cold-start emissions than conical sensors. Compared to other switching sensors, Delphi's Switching Oxygen Sensors offer a pumped air reference and feature an isolated ground. They also feature industry-leading poisonresistant coatings, waterproofing, and a high-temperature internal seal to provide robust reliability versus other switching sensors. www.delphi.com | © Delphi.
