Wideband o2

What’s a Wideband Oxygen Sensor?

A wideband oxygen sensor (generally known as a wideband O2 sensor) is a sensor that measures the ratio of oxygen to gas vapor within the exhaust exiting an engine. The measured ratio is expressed as components of oxygen to gas. If there may be 15 components of oxygen to each one a part of gas, this is able to be expressed as an air/gas ratio of 15 to 1, or 15.0:1.

A wideband oxygen sensor permits the air/gas ratio to be measured over a really broad vary (typically from round 5:1 as much as round 22:1). The inventory oxygen sensor (often a NARROW-BAND sensor) can solely measure the air/gas ratio over a really slim vary (typically from solely round 14.5:1 as much as 15.0:1).

How does the ECU use a narrowband oxygen sensor?

Your manufacturing unit ECU makes use of the output from a narrowband oxygen sensor to regulate gas trim primarily based on engine working circumstances and setting. The ECU makes an attempt to maintain the engine working round 14.7:1 for optimum engine longevity and gas effectivity whereas sustaining low emissions. If the ECU ‘sees’ an air/gas ratio of 14.5:1, it should barely lower injector period to lean out the gas combination to round 14.7:1. If the ECU ‘sees’ an air/gas ratio of 15.0:1, it should enhance injector period to richen the air/gas combination. This works properly on a inventory engine, however for optimum efficiency a perfect air/gas ratio is way richer (typically from 12.0:1 as much as round 13.5:1). The inventory narrowband O2 sensor merely can not distinguish this air/gas ratio and due to this fact can not adequately inform the ECU how a lot gas so as to add or subtract. That is the place the benefit of a wideband O2 sensor shines! A wideband oxygen sensor will permit the ECU to learn a a lot ‘wider’ vary of air/gas values due to this fact permitting the tuner to make the correct changes for optimum efficiency.

What to search for when buying a wideband oxygen sensor:

When utilizing a wideband O2 sensor to learn air/gas ratios and tune an engine, there are a number of qualities to search for.

1. Accuracy is high precedence. If the wideband’s readings are inaccurate, it’s possible you’ll make gas changes in error leading to a lack of energy and even worse, engine injury.

2. Pace. The wideband should be conscious of modifications in air/gas ratio to permit correct gas changes for modifications in engine rpm and cargo.

3. Ease of set up/ Compatibility. The wideband oxygen sensor should be appropriate along with your tuning software program, {hardware}, and set up wants.
