BOSCH wideband air/fuel ratio sensors utilize a more sophisticated sensing element that enables them to produce a precise output in proportion to the air/fuel ratio. As a result, a wideband A/F sensor measures exhaust gas oxygen accurately from as rich as 9.0:1 to as lean as free air. The use of the wideband A/F sensors is growing rapidly as original equipment in vehicles and in high-performance specialty markets.
- Accurate lambda measurement in a wide air-fuel ratio range
- Continuous (linear) lambda control possible.
- Faster light-off time for faster closed-loop control after cold start to meet tighter emissions standards (UL EV, SUL EV)
- Consistent performance over time.
