Most diggers and construction machines discharge unfiltered exhaust fumes into the air. This is because special vehicles are made in small batches, and each requires a different filter geometry.

Modern diesel vehicles of all sizes are equipped with complex aftertreatment systems to reduce exhaust emissions. The diesel particulate filter (DPF) plays an important role in these systems by ...

Truck DPFs are among the hundreds cleaned by Ceramex per week ...

You may recall when the EPA mandated that, starting in 2007, all new on-highway diesel engines must limit the emission of particulate matter. To comply with this regulation, equipment makers ...

Diesel particulate filters trap soot from the exhaust and ash from motor oil. Most soot is burned off in the course of a truck's operations, but ash stays in the filter's honeycomb substrate and is ...

I'm aware that modern diesel engines have particulate filters that can be unsuited to repeated short journeys (require a long run to clean them up, e.g. Mazda 5 diesel). When did manufacturers start ...
