Diesel continues to be a hot topic in the news and the recent changes to the MOT test has brought the subject of vehicle emissions back into sharp focus, plus the growing need for DPF cleaning.

A Diesel Particulate Filter (DPF) reduces soot emissions from a vehicle’s exhaust systems by up to 80%. Euro 5 emissions legislation saw DPFs become mandatory for all new diesels from January 2013 and a check for a DPF in the inspection of the exhaust system has been part of the MOT test for over four years.
 
DPFs work by trapping bits of soot from incomplete combustion in the exhaust system.  The DPF is structured like a series of honeycomb filters that prevent the soot passing all the way through the filter into the atmosphere, thereby reducing emissions.
 
However, as sales of diesels grew exponentially from 2000, DPF blockages became commonplace, especially in vehicles used in low mileage, urban driving cycles. DPFs are designed to effectively self-clean in a process called ‘regeneration’, where the soot is burnt off the filter at a high temperature, typically when a vehicle is travelling consistently at moderate to high engine speed.  However, if a vehicle is frequently used to travel short distances, the vehicle is unlikely to produce the exhaust temperatures required to enable regeneration to take place, resulting in excessive soot build up and a drastic reduction in vehicle performance.
 
In addition to its market leading range of remanufactured engines and major units, Ivor Searle now provides a professional, off-vehicle Diesel Particulate Filter (DPF) cleaning service for cars and vans.
 
Utilising patented Flash Cleaning technology, the environmentally-friendly process delivers as new levels of cleanliness by removing all soot deposits, including PM10 particles, cerium oxide deposits and oil residues from the DPF. Unlike chemical-based DPF cleaning processes, which only remove soot, Flash Cleaning eliminates both soot AND ash deposits, to return a DPF back to OE levels of performance at a much lower cost than purchasing a new unit. Because it’s a chemical free process, this means the DPF sensors can remain in the filter, as they are unaffected.
 
Ivor Searle’s fast turnaround professional DPF cleaning service gives factors and fleet operators a competitive advantage, by offering a lower cost alternative to component replacement. 
 
David Eszenyi, Ivor Searle’s Commercial Director, said: “Having built up a reputation for excellence in our remanufactured products, we’re pleased that our new DPF cleaning service is gaining momentum across the aftermarket. As awareness of this additional service builds, we expect capacity to grow significantly this year. Now that we have the equipment in-house, it will make DPF cleaning even more cost-effective for customers.“
 
To guarantee peace of mind, all Ivor Searle cleaned DPFs are provided with certified pre- and post-cleaning back pressure and flow reports, as well as the reassurance of a no quibble 12-month unlimited mileage warranty.  To find out more please call the Ivor Searle sales team on 01353 720531.
