Delphi Wide Range Oxygen Sensor The Delphi Wide Range Oxygen Sensor is an integral component in a gasoline or diesel engine management system, helping provide accurate engine control and system diagnostics. It measures the air⁄fuel ratio of exhaust gases over a wide lambda range. Its fivewire, two-cell design enables higher signal resolution with greater accuracy. An integrated heater and alumina/zirconia element facilitate a fast light-off, allowing earlier closed-loop operation compared to conventional conical oxygen sensors. High signal resolution and low pressure sensitivity help provide precise engine control Integral heater enables faster light-off for earlier closed-loop operation Unique planar element design enhances thermal shock resistance Fast response helps improve fuel economy Industry-leading poison-resistant coating helps achieve better durability and truer reading of exhaust gases Typical OSL Output Curve Delphi's Wide Range Oxygen Sensor with planar element technology helps provide accurate engine control and system diagnostics. Note: The Delphi Wide Range Oxygen Sensor characteristic output is linear to percent oxygen in the exhaust. Typical Applications The Delphi Wide Range Oxygen Sensor is an integral part of diesel and gasoline engine management systems where additional control is desirable. With different shielding options, the sensor can be tailored for specific applications in passenger vehicles, commercial vehicles, motorcycles and other engine applications. www.delphi.com | © Delphi.
