Truck and Bus Regulation
On-Road Heavy-Duty Diesel Vehicles (In-Use) Regulation
The regulation requires diesel trucks and buses that operate in California to be upgraded to reduce emissions. Heavier trucks must be retrofitted with PM filters beginning January 1, 2012, and older trucks must be replaced starting January 1, 2015. By January 1, 2023, nearly all trucks and buses will need to have 2010 model year engines or equivalent.
The regulation applies to nearly all privately and federally owned diesel fueled trucks and buses and to privately and publicly owned school buses with a gross vehicle weight rating (GVWR) greater than 14,000 pounds. Small fleets with 3 or fewer diesel trucks can delay compliance for heavier trucks by reporting and there are a number of extensions for low-mileage construction trucks, early PM filter retrofits, adding cleaner vehicles, and other situations. Privately and publicly owned school buses have different requirements.

Rincon Truck Center carries a full line of passive and active diesel particulate filters for your vehicle needs.
Engine Control System has both active and passive systems, engine model years from 1993 to 2010 EGR and non-EGR engines.
Purifilter
- The Purifilter employs a base and precious metal catalyst impregnated onto the silicon carbide DPF surface to passively oxidize accumulated particulate while complying with stringent California Air Resources Board (CARB) limits on NO2 emissions.
- The bottom line is that your investment in Purifilter™ delivers the most effective, durable and quiet solution to your environmental mandate.
Purifilter Plus
Purifilter™ Plus combines the benefits of Combifilter’s active regeneration with Purifilter’s passive operation to provide the combined benefits of both products
Purifilter™ Plus employs a passive Purifilter DPF to allow extended periods of passive operation with periodic active regeneration at a optimal interval determined for your equipment (i.e. weekly, biweekly, every preventative maintenance, etc.) to
- increase Purifilter™ tolerance of duty cycle variations
- provide a proactive fleet management / maintenance tool that insures equipment availability / up-time, low backpressure, fuel economy, and ease of on-board service without DPF removal
- reduces infrastructure investment by allowing regeneration equipment to be used to support a wide number of Purifilter installations.
HUG Filter Systems, just approved by CARB for installation on non-EGR, 1991 to 2006 engnies between 100-600hp (CAT ACERT and non-EGR engines with NOx certification rating <3.0 g/bhp-hr are excluded). The Mobiclean R advanced filter system is a passive regeneration system.
As with all Hug filter systems, mobiclean R advanced uses an enclosed, catalytic coated substrate. Only with this kind of enclosed filter system can an efficiency of soot reduction of 97% be achieved. The substrate’s base material consists of silicon carbide.
In addition to the mobiclean R basic, the mobiclaen R advanced is equipped with a preoxidation catalyst. This allows regeneration starting at a low 210 degrees Celsius.
