air/fuel ratio (lambda)
lambda (excess air ratio)
The lambda sensor works out the correct ratio by determining how much oxygen is still in the exhaust gas and then passes this information on to engine control so that the fuel quantity can be adapted.
To optimise hydrocarbon conversion, the lambda sensor uses a saw-tooth profile for rich/lean peaks.
With the new condensation test stand, engine mechanics now have a tool they can use to precisely determine the
release time for lambda sensing.
A solid ion-conducting ceramic
material, yttrium-doped zirconium dioxide,
also used in lambda oxygen sensors in automotive
applications, is used as the electrolyte in solid electrolyte
fuel cells (SOFC).
