Key Points

This system integrates a radiofrequency (RF) plasma reactor operating at 915 MHz (200–800 W) with a FeCoNiCrMn-coated high-entropy alloy (HEA) catalyst on a 400 CPSI cordierite substrate. Enhanced by IoT sensors and CAN FD data transmission, it achieves real-time emission monitoring and control, delivering an 80% NOx reduction and 95% PM removal at 600 W, compliant with Euro 6 and EPA Tier 4 standards.
