American ECM Rapid Air Fuel Ratio Analyzer Lambda5220summary:

American ECM Rapid Air Fuel Ratio Analyzer Lambda5220It is a powerful next-generation Lambda/AFR/O2 analyzer, equipped with CAN interface, providing measurement range and accuracy. All sensors are calibrated in the factory, and calibration data is stored in the storage chip of the connector. To provide the best measurement accuracy, the sensor can be quickly recalibrated in ambient air, and the recalibrated data is also stored in the connector storage chip. Optional pressure compensation is used to improve measurement accuracy under non theoretical mixed gas (λ ≠ 1) and non-standard atmospheric pressure conditions (P ≠ 101KPa). For example, a 34KPa increase in pressure will result in an error of 0.58 (λ=3), and pressure compensation is used to eliminate this measurement error.
The Lambda5220 analyzer is compatible with sensors such as BOSCH LSU4.2/4.9, NTK 4mA/6mA, DELPHI OSL, etc. The fuel composition ratios of H: C, O: C, N: C, and H2 can be set.
Lambda5220 outputs Lambda, AFR, Φ,% O2, pressure (options), and other sensor parameters such as pump current, resistance, sensor aging factors, etc.
The Lambda5220 analyzer is suitable for bench and vehicle use, with six analog outputs, CAN, USB, RS232 communication. The Lambda5220 analyzer can be connected to any data acquisition system. The connection cable between the sensor module and the display can be up to 100 meters long.
For the convenience of in car use, the Lambda5220 analyzer can be turned on and off through the car ignition switch signal.
Lambda is the most important parameter that affects exhaust emissions, fuel economy, and engine performance, so it must be accurately measured. For over a decade, ECM Corporation in the United States has provided Lambda measuring instruments for automotive and engine research and development units, and its Lambda5220 analyzer represents the * technology for Lambda/O2 measurement.
