Rypos Gains CARB DPF/ULETRU Verification for New Engines

Posted by Rypos on Aug 18, 2020 10:30:00 PM


The California Air Resources Board (CARB) has modified the RYPOS DPF/ULETRU Diesel Particulate Filter System verification with a new parts list and updated engine family lists to include new off-road diesel engines rated at up to 50 horsepower.

The Rypos DPF/ULETRU is a Level 3+ diesel emission control strategy (DECS), capable of reducing emissions of particulate matter (PM) by 85 percent or more without increasing nitrogen dioxide emissions to more than 20 percent of total nitrogen oxides.  The RYPOS system consists of a diesel oxidation catalyst (DOC), an active exhaust filter and an automatic filter regeneration system.  Specific engine models and families that may qualify are listed in the Engine Family List at CARB's Verification Procedure Website for the original Rypos DPF/ULETRU and Rypos DPF/ULETRU for Thermo King multi-temperature TRUs.
