Radio-Frequency (RF) Technology for Filter Microwave Regeneration System * 2000-01-2845

A new diesel exhaust particulate trap system was developed to control diesel particulate emissions from buses in large cities in China. This system was equipped with a microwave heater for the purpose of filter regeneration. To achieve effective and efficient filter regeneration, a radio-frequency (RF) technology was employed. The RF technology measured the amount of particulate trapped in filter, and it controlled filter regeneration using microwave signal. In this paper, the on-line diesel particulate measurement system was described, and experimental study of this measurement system was reported. The experimental results proved the effectiveness of the RF technology in the application of this diesel particulate trap system.
