Understanding the MOOCAR PM Sensor in Modern Vehicles A Particulate Matter (PM) sensor is a critical component of modern vehicle emission control systems, particularly in diesel engines and gasoline vehicles equipped with Gasoline Particulate Filters (GPF). Its primary function is to monitor real-time concentrations of soot particles (PM2.5/PM10) in exhaust gases and transmit data to the Engine Control Unit (ECU). This enables optimization of combustion efficiency and ensures compliance with stringent emission standards (e.g., Euro 6, China 6B). MOOCAR PM sensors, renowned for their high-precision detection capabilities, help vehicles maintain a balance between low emissions and high performance under diverse operating conditions. Alongside the PM sensor, other key components in the emission control ecosystem include EGT sensors (Exhaust Gas Temperature Sensors), NOx sensors, oxygen (O2) sensors, and differential pressure sensors, all of which work together to ensure reliable aftertreatment monitoring and system efficiency.
