Versatile wideband lambda module suits diesel and gasoline engines under test in dynamometers and vehicles
 

Labcell has introduced the ECM LambdaCAN module for in-vehicle and dynamometer testing of diesel and gasoline (petrol) engines where a wide measurement range and fast response are required. Being CAN-compatible means that the lambda (air-fuel ratio) module is easy to integrate within a CAN-based control and monitoring system, and the optional pressure compensation results in dramatic improvements to accuracy when the engine is operating in non-stoichiometric or non-atmospheric conditions.

Designed for use by professional engine designers, developers and tuners, and capable of operating with Bosch or NTK-type next-generation wideband sensors, the LambdaCAN measures from 0.40 to 25 lambda (and AFR from 6.0 to 364, and %O₂from 0 to 25) with an accuracy of +/-0.005 lambda at stoichiometric and with a response time of less than 150ms. One sensor (and one programmable LambdaCAN module) can be used for any fuel, with the sensors being factory calibrated and the calibration data stored in a chip installed within the sensor's connector. Recalibration can be performed in ambient air, with the revised data also stored in the chip. This ease of recalibration helps to overcome the problem of sensor aging that can otherwise be a significant source of error in lambda/AFR/O₂measurements.

Compact, sealed to IP67 and with an operating temperature range of -55 to +125 degrees C, the LambdaCAN module can be readily installed within a vehicle or in a dynamometer cell. Data for lambda, AFR or O₂can be displayed and/or logged via a high-speed CAN network, recorded by an in-vehicle laptop, or the optional ECM dashCAN two-channel display provides users with at-a-glance visualisation of current values. Alternatively, the LambdaCAN module can be connected to the ECM 5220 Lambda Analyser for in-vehicle or dynamometer applications, and up to 16 LambdaCAN modules can be multiplexed when monitoring individual cylinders.

For applications requiring operation at non-stoichiometric conditions, the LambdaCAN module's optional pressure compensation improve accuracy considerably. Pressure compensation also enables the module to be used for applications such as the measurement of percentage oxygen in the inlet manifold.

The wide-band LambdaCAN module is extremely versatile, particularly when equipped with the optional pressure compensation, so one device meets the needs of virtually all lambda/AFR/O₂measurement requirements, whatever the fuel, and whether the testing takes place in a dynamometer or vehicle. Labcell also offers similar modules for measuring NOx, NH₃and operating parameters including temperature, pressure and exhaust gas recirculation.
