Control System of Diesel Particulate Filter Regeneration Equipment Based on LPG
This paper give a diesel particulate filter (DPF) regeneration equipment based on LPG (Liquefied Petroleum Gas), which the filter bodies of both the DPF were made of winded metal mesh, to fit for the high sulfur diesel. Development of performance external LPG heating regenerative devices can be completed within 20 minutes DPF regeneration. This regenerative device control system using MCU by reading the temperature controller and pressure sensor data, output analog quantity to control the frequency converters, which control blower speed to achieve the control of air flow into the burner, to achieve temperature control. To ensure system security, the use of burner control to achieve the various components of the control scheduling. It is cheap, good durability, a high degree of confidence. Because they do not use the catalyst can be regenerated, so it can be used in high-sulfur diesel.
