Hug Filtersystems announced that the California Air Resources Board has verified its mobiclean R diesel particulate filter for use with most non EGR on-road diesel vehicles from 1991 to 2006.

The mobiclean R system provides emission reductions of diesel particulate matter by at least 85%, according to the company, and is designated as a California Level 3 Plus system. It can be applied to diesel engines from 3.4 to 16 liters (100 to 600 horsepower) in any type of on-road applications. Temperature requirements are only 200 degrees Celsius for 15% of the time in a duty cycle, Hug stated.

The Hug Filtersystems mobiclean R filter does not require any filter cleaning due to its self-cleaning capabilities, the company stated. The self-clean regeneration starts at 200 degrees Celsius.

The company said this application works well with vehicles used in stop-and-go city traffic, such as school buses, municipal utility trucks, and waste haulers.
