AI Technical Summary

Technical Problem

Existing exhaust gas sensors in internal combustion engines face accuracy and reliability issues due to positioning and flow disturbances, which affect the efficiency of downstream engine after-treatment systems, making it difficult to comply with emissions legislation.

Method used

A sensor mounting module that increases the pressure differential between the inlet and outlet to enhance the velocity of the exhaust gas flow through the sensor passage, improving accuracy and reliability by ensuring the gas flows through a defined path and preventing bypasses.

Benefits of technology

The increased velocity of the exhaust gas flow enhances the accuracy and reliability of the sensor measurements, ensuring compliance with emissions legislation by effectively quantifying exhaust gas properties.
