Adaptation Lambda probe
Lambda and Tuning
Oxygen sensors are mainly used in petrol and diesel engines, but they are also used in the exhaust systems of pellet or gas heaters are used. The Lamda probe is favored in gasoline engines in the exhaust manifold or on the rearCollector tube installed. For vehicles /
Engines who want to meet higher emission standards (eg EURO 5), multiple probes are mostly used (see also the concept monitor probe). For motors with V cylinder arrangement usually each a Lamdbasensor per cylinder bank are installed. In art engines, with selective cylinder deactivation, even each have a sensor on each cylinder are installed.
If the emission of nitrogen oxides, hydrocarbon or soot regulated / controlled, then comes mostly a lambda probe used. The oxygen sensor is in catalyzing emission so that the main sensor in the control circuit (regulated catalyst).
Come in tune racing or motor sport exhaust systems are used, then these contain very often a so-called sport catalyst (often with 100 / 200 cells). After installing powerful sports catalysts necessarily a calibration of Lamda control in engine control unit should be. The experts from SKN can provide you with such an adjustment / calibration as part of a chip tuning. So you can be sure that the exhaust gas purifying working again without errors after successful programming and exhaust tray served its purpose.
Functioning of the lambda probe
The operation of a lambda probe (λ probe) is relatively simple. The probe simply compares the residual oxygen content in the exhaust gas with the oxygen content of the current ambient air. From this a so-called air-fuel ratio can be determined and adjusted. The combustion ratio is the ratio of combustion air to fuel. The lambda probe can thus the gasoline-air mixture enriched (more fuel) or lose weight (less fuel).
