WebLambda is used to express the air ratio between the theoretical air requirement and the actual air flow supplied: λ = supplied air flow : theoretical air flow = 14.7 kg : 14.7 kg = 1. … WebThe Wideband Air/Fuel Sensor The newest generation of oxygen sensors are being called "wideband" lambda sensors or "air/fuel ratio sensors" because that's exactly what they do. They provide a precise indication of the exact air/fuel ratio, and over a much broader range of mixtures - all the way from 0.7 lambda (11:1 air/fuel ratio) to straight air!
Bosch Wideband Oxygen Sensors Precisely Measure Air/Fuel …
WebApr 12, 2024 · The sensor was located downstream of a diesel oxidation catalyst (DOC) and a diesel particulate filter (DPF). A thermocouple and a commercial UEGO sensor (YSZ wide band oxygen sensor acc. to ) were placed next to the sensor position to measure the exhaust temperature T Exhaust and the air-fuel ratio λ. The exhaust mass flow m ˙ was … WebAdvantages of LSU4.9 lambda sensor technology (versus LSU4.2) Improved accuracy and reliability – LSU 4.9 uses pumping current as a reference, while LSU 4.2 uses a reference air cell. Over time this reference air cell becomes contaminated. This shifts sensor readings to the low side. However, LSU4.9 doesn’t use a reference air cell at all ... how to select multiple files on mac to delete
