Volvo Truck has announced details of its particulate filter that it will be fitting to vehicles produced at the upgraded US facility in Hagerstown, Michigan.

The plant is to be given a $150 million facelift in order to prepare it for the production of both Mack trucks and North American Volvos, with the facility to deliver the latest in clean emissions technology.

One of the key facets of the new production line will be the particulate filter designed to meet stringent 2007 US federal standards.

The particulate filter is coated in platinum to enhance the catalytic reaction, and is also self-cleaning according to reports on e-trucker.

When idling or running unencumbered by a heavy load, the engine is able to clean the filter using a fuel injector in the exhaust system.

This ten-minute process can take place between every four and 16 hours of usage, maximising the capacity of the particulate filter.
