Naas headquartered Volvo Truck & Bus Dealership Irish Commercials has introduced a new Diesel Particulate Filter (DPF) cleaning service. Using state-of-the-art equipment to thoroughly and completely clean HGV diesel particulate filters, it reduces vehicle downtime, increases fuel economy and significantly protects against DPF failure.
DPFs are designed to remove particulate matter in the diesel exhaust. However, over time deposits of soot and ash captured in the DPF increase the backpressure on the engine, eventually reducing the fuel efficiency. Most engine manufactures recommend removing the DPF for cleaning from 160,000 kilometres, however research and testing has found that sometimes ash begins hardening in the filter cells as early as 100,000 kilometres. Once ash hardens, it can cause permanent damage and cracking, so, thorough removal of this ash is essential for the operating efficiency of the engine as well as optimising the length of time between service intervals.
Testing is the first stage in the process and is done on the FSX TrapTester, an airflow test bench that measures the amount of resistance the DPF has to airflow through the filter. As a DPF fills up with dust it creates additional resistance to airflow, thus increasing backpressure on the engine. This measurement is the basis for determining the effectiveness of the cleaning engine process.
How it works:
- Stage 1 – Testing/ Inspection. An airflow test bench is carried out to measure the amount of resistance the DPF airflow through the filter. This measurement is the basis for determining the type of cleaning process.
- Stage 2 – Trap Blaster Pneumatic Cleaning. The DPF is subjected to high pressure scanning air jets on both ends of the filter. This process individually targets each of the many cells of the filter to remove as much dust as possible.
- Stage 3 – Trap Burner Oven for Deep Cleanse. The FSX TrapBurner heats the DPF to oxidise any soot trapped in the filter and loosens ash deposits. The thermal cleaning process is not necessary for every filter. Proper employment of the inspection and testing processes will determine when the thermal cleaning process is required.
