Delphi has been one of the leading suppliers of oxygen (O2) sensor technology since 1978, and our OE and aftermarket engineers collaborated to develop the most innovative oxygen sensors for the aftermarket. Delphi planar technology helps reduce emissions  in fact, we lead the industry in contamination resistance to silicone, phosphorous and other fuel/oil additives, thanks to our patented protective sensor coating. Our planar O2 sensors also feature OE connectors and wire lengths within three inches of OE specifications. This translates into easier installation and resistance to high temperatures, vibration damage and wire corrosion, which protects signal accuracy and longevity. Delphis patented sensor construction and design provides long-lasting, reliable operation during sensor life and the industrys fastest light-off times to reduce cold-start emissions, not to mention improved fuel economy over aging sensors. Our unique sensor coatings protect elements from premature failure and are validated for lifetime operation with E85 and other alcohol-based fuels. And our planar O2 sensors are configured and designed to replace previous conical sensor designs for maximized coverage and inventory management.

 

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 airÔüäfuel ratio of exhaust gases over a wide lambda range. Its five-wire, two-cell design enables higher signal resolution with greater accuracy. An integrated heater and aluminaÔüäzirconia element facilitate a fast light-off, allowing earlier closed-loop operation compared to conventional conical oxygen sensors.

Benefits

  • 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

Note: The Delphi Wide Range Oxygen Sensor characteristic output is linear to percent oxygen in the exhaust. The output curve can be made linear to lambda (AF) if desired.

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.

Availability

In serial production. Samples are available for manufacturers. Contact Delphi for further information.

Performance Advantages

Designed to accommodate a variety of fuel applications, the poison-resistant coating of the Delphi Wide Range Oxygen Sensor helps improve accuracy and durability in harsh exhaust environments, while minimizing deterioration of the sensor characteristics over time. Its uniquely designed planar element technology and integral heater enhance resistance to thermal shock and help the sensor achieve fast light-off to help manufacturers meet current and more stringent future emissions regulations. The sensor’s greater accuracy and a fast transient response time help provide greater engine control, and help improve fuel economy and drivability.

Oxygen Sensor Types, Technologies & Common Failures

Engine Management System: The Basics

The purpose of the engine management system (EMS) is to apply the correct amount of gasoline to the air entering the engine, while igniting the compressed air/fuel mixture at the right time within the cylinder. When an average Stoichiometric ratio of 14.7 lbs. of air to 1 lb. of gasoline is maintained, the EMS provides adequate oxygen for the reduction of harmful pollutants, as well as a rich enough mixture to prevent the catalyst from overheating.

The EMS uses one or more oxygen sensors to monitor combustion by measuring the oxygen content in the exhaust. And, in order for the catalytic converter to perform at its full potential, the EMS uses information from the oxygen sensors mounted before and after the catalytic converter.

Oxygen Sensors: The ‘How’ and ‘Why’

Oxygen sensors have to reach an approximate operating temperature between 600? and 650? F to produce valid data for closed-loop fuel control. In order to enter closed-loop sooner, oxygen sensors are equipped with a heater circuit, which provides power from a fused source and is ground-switched by the EMS processor.

Upstream oxygen sensors (typically located in the exhaust manifolds) are used to maintain control over the air/fuel mixture. Downstream oxygen sensors (located in the exhaust stream after the catalyst), are used by the EMS to monitor catalytic converter efficiency. In some engine management configurations, downstream oxygen sensor activity is used to adjust the air/fuel operation to maintain a favorable ratio to optimize catalyst efficiency.

Common Types of Oxygen Sensors

While all oxygen sensors serve the same purpose  to provide feedback to enable the EMS to maintain a suitable air/fuel ratio  several types of sensors can be found in current production vehicles.

Common oxygen sensor types include:

    1) Zirconia dioxide
    2) Planar
    3) Titania
    4) Wide-band air/fuel ratio.

 

1) Zirconia dioxide oxygen sensors generate a voltage proportionate to the oxygen content of the exhaust. When the oxygen in the exhaust is high (lean mixture), the voltage produced is low.

Conversely, rich mixtures (low oxygen content) are indicated by high voltage. The voltage range is 0 to 1 volt.

2) More stringent exhaust emission requirements in the mid-1990s led to the development of heated planar sensors, which deliver a reading that can be used for accurate fuel control within 12 seconds after an engine is started. First introduced in 1998, planar sensors now account for about 50 percent of oxygen sensors installed in new vehicles in the United States, and that number is growing rapidly.

3) The Titania oxygen sensor is a variable resistor-type sensor. As the oxygen content in the exhaust changes, the resistance of the oxygen sensor changes, too. Depending on the condition (rich or lean), the resistance causes the sensor reference voltage to rise or fall. A lean condition will cause the Titania oxygen sensor to output a high voltage signal. The voltage range is typically 0 to 5 volts.

4) Another type of oxygen sensor is the AF sensor, also called a Lean Air Fuel sensor (LAF). The LAF sensor improves overall efficiency by keeping the fuel control system in closed-loop during a wider range of driving conditions. Subsequently, instead of using preprogrammed, open loop air/fuel ratios in many situations, the ECM/PCM fine-tunes the mixture more closely based on actual oxygen readings.

Common failures and faults

As an oxygen sensor deteriorates, it can cause excessive gasoline consumption and elevated exhaust emissions while accelerating catalytic converter damage.

The deterioration can also lead to engine performance problems such as surging and hesitating. A deteriorated sensor can also contribute to sluggish engine performance caused by a rough idle from too lean a mixture.

Any time vehicle tailpipe emissions exceed 1 times federal limits, the EMS processor is programmed to record fault data. The Malfunction Indicator Lamp will illuminate after two consecutive faulted trips, and the oxygen sensor and its associated circuits are monitored for defects.

Oxygen sensor and/or oxygen sensor circuit faults (including the heater circuits) can prevent the EMS from entering closed-loop. These faults can also set DTCs in memory and prevent some on-board diagnostic tests from running.
