Adaptation Lambda probe

Lambda and Tuning

Lambda probes are mainly used in gasoline and diesel engines, but they are also used to regulate the exhaust gas in pellet heating systems or gas boilers. The lambda probe is favored in gasoline engines in the exhaust manifold or just behind the Collector 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).

Motorsport catalysts

If exhaust systems are used for tuning racing or motorsport, these very often contain a so-called sports catalytic converter (often with 100/200 cells). After installing powerful sports catalytic converters, it is essential to calibrate the lambda control in the engine control unit. The experts at SKN can provide you with such an adjustment / calibration as part of a chip tuning. So you can be absolutely sure that after successful programming, the exhaust gas cleaning will work again without errors and that your exhaust gas disposal will serve 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).
