MoTeC Lambda Sensor

Производитель: MoTeC

Wideband Lambda sensors are designed to give an exact reading of Lambda. This is particularly useful when the precise mixture needs to be known in order to tune the engine for optimum power. The measuring range can span from 0.7 to 32 Lambda for a 5 wire sensor type.
Wideband Lambda sensors use sophisticated controls, as the temperature change needs to be taken into account to be accurate.
There are two concepts for measuring wideband Lambda:

4 Wire Wideband Lambda Sensor
This technology takes advantage of the fact that the sensors voltage output is based on not only the oxygen differential between the exhaust pipe and atmosphere, but also on the temperature of the sensor itself. Sensor impedance varies with temperature, so not only the sensor voltage, but also the sensor impedance needs to be measured. Systems which do not use at least four wires typically have errors in displayed Lambda as high as 8 percent!

5 Wire Wideband Lambda Sensor
This newer technology determines the air fuel ratio of an engine by measuring Lambda sensor voltage output and the current required to hold the sensor voltage output constant. This method offers increased speed and accuracy over the older 4 wire sensor technology.

Tuning with Lambda
The tuning objective dictates the target Lambda. Typical gasoline/petrol engines produce

peak power at Lambda between 0.84 and 0.90
best economy at Lambda equal to 1.05
optimal emissions at Lambda slightly lower than 1

MoTeC ECUs allow for a Lambda goal table based on load and RPM.

Referencing the measured Lambda, the Quick Lambda function in the software adjusts the values in the fuel control table at the specified load and RPM site to achieve the goal Lambda.

Similarly, the Lambda Was function adjusts the values in the fuel control table using recorded Lambda measurements from a data log.
