Business car operator association ACFO has issued new advice to its members over diesel particulate filters which trap sooty emissions from vehicles.
The advice warns fleets to ensure that only employees “whose routine driving will allow them regular opportunity to drive at 50mph or more, for 20 minutes or so” have cars with diesel particulate filters.
This has been issued to avoid the possibility of soot traps becoming clogged, which can then potentially damage a car’s engine. Soot traps self-clean by burning, at high temperatures, the particulates generated from diesel engines to create ash. In some cars the higher temperatures are only generated at higher speeds typically seen in motorway driving.
