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.

Rypos is known for innovating the future of clean air through intelligent emissions reduction built on the company’s patented electrically self-regenerating filters. With over 13,000 DPF’s sold, the Rypos DPF ULETRU has been engineered to work seamlessly with both Thermo King® and Carrier® refrigeration units without the need for any operator interaction. Rypos should be the 1st choice for any TRU operator or fleet entering California where they must comply with the CARB TRU ATCM.

Fine Particulate Matter

Wrapping up an investigation begun four years ago, the California Air Resources Board announced July 1 it fined brewing company Anheuser-Busch $500,000 for medium- and heavy-duty trucks that violated the state’s air pollution laws.

CARB launched its investigation in March 2015 and discovered that the St. Louis-based brewing company had failed to properly self-inspect 19 diesel trucks, as required by the state’s Periodic Smoke Inspection Program, to ensure they met state smoke emission standards.

In addition, CARB staff discovered that Anheuser-Busch was not in compliance with the state’s Truck and Bus Regulation because they failed to meet required compliance deadlines. A total of 86 trucks were noncompliant with the applicable in-use performance standards, according to the Sacramento, Calif.-based agency.

A CARB spokeswoman told Transport Topics the investigation of the Class 6 through 8 trucks was begun following an anonymous tip. The company’s fleet headquarters is in San Diego.

Anheuser-Busch did not immediately respond to a request for comment.

“California has some of the country’s poorest air quality and because of this, our laws are tough to protect public health. All businesses must do their part to ensure their fleets are fully compliant with California’s anti-pollution regulations that are designed to clean our air and protect our children,” CARB Enforcement Division Chief Todd Sax said in a release.

Owners of older cars and light trucks in California have long known that smog certification is required every other year as a condition of vehicle registration. No certification, no registration. It’s been that way since 1984. Big rigs, unlike passenger vehicles, don’t have to pass state smog checks. Diesel trucks spew the major portion of oxides of nitrogen and diesel particulate matter into California’s air.
