How do wide band lambda sensors work
WebThe pre-cat sensor is fitted into the exhaust pipe before the catalytic converter, and cars using the new EOBD2 also have a post-cat lambda sensor. The sensors have a varying number of electrical connections, up … WebJul 10, 2013 · When you think in lambda, it's always the same, 1. Except that ALL widebands measure lambda, they don't measure AFR. The controller converts from lambda to AFR by multiplying by whatever stoich you tell it, usually 14.7. So logging lambda vs logging AFR and dividing by 14.7 will give you identical results.

WebOct 1, 2008 · Lambda is the Greek symbol used to represent the air/fuel ratio. At stoichiometric, lambda equals 1. Lean mixtures have a lambda value greater than 1, while rich mixtures have a lambda value less than one. The lambda PID reading can be converted to a numeric air/fuel ratio for air and gasoline by multiplying the Lambda value times 14.7. WebDec 28, 2015 · Lambda sensors work at elevated temperatures, around 300 °C (600 °F); many lambda sensors contain a resistive heater element to help get them up to temperature quickly. Narrowband These qualitatively detect whether the exhaust gases are rich or lean.
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 ... WebThe wide-band O 2 sensor is composed of two inner layers called the reference cell and the pump cell. The ECM's AFR sensor circuitry always tries to keep a perfect air/fuel ratio …
