What is a particulate matter (PM) Sensor?

Particulate matter sensors play a crucial role in diesel exhaust systems, especially in the context of controlling emissions and complying with environmental regulations. Here’s how particulate matter sensors are commonly used in diesel exhaust systems:

Particulate Filter Monitoring:

*Particulate matter sensors are employed to monitor the effectiveness of Diesel Particulate filters by measuring the amount of particulate matter before and after the filtration process.

*If the filter becomes clogged or less effective over time, the sensor data can trigger regeneration processes or alert the vehicle operator or control system to take corrective action.

Emission Control Systems:

*Particulate matter sensors are integrated into emission control systems to ensure compliance with environmental standards and regulations.

*Real-time monitoring of particulate matter levels allows for dynamic adjustments to engine parameters or exhaust treatment systems to optimize combustion and reduce emissions.

On-Board Diagnostics (OBD):

*Particulate matter sensors are often part of on-board diagnostics systems in modern vehicles. OBD systems monitor the performance of various vehicle components, including the exhaust system.

*If the sensor detects high levels of particulate matter, it may trigger a fault code, indicating a potential issue with the emissions control system.

Regeneration Control:

*Diesel particulate filters (DPFs) can become clogged with accumulated soot over time. To address this, regeneration processes are used to burn off the collected particulate matter.

*Particulate matter sensors provide data to control systems, helping determine when regeneration is needed. Regeneration can be initiated automatically by the vehicle’s engine control unit based on sensor readings.
