Rypos
The
ARB has
verified Rypos, Inc.
Active Diesel Particulate Filter (ADPF) diesel particulate filter for
1996 to 2008 diesel engines certified to Tier 1, 2, or 3 PM emission
rate used in stationary emergency standby applications. On December 18,
2008, ARB verified that
this system complies with the January 1, 2009 NO2 limit; the
system is
therefore verified as a Level 2 Plus diesel emission control
device. For complete information please view the Executive Order
and Engine
Family List below.
Engines must meet the following operating criteria:
| Parameter | Value |
| Application | Emergency Standby Stationary Power Generation |
| Engine Type | Diesel, with or without turbocharger, certified off-road engines meeting 0.4 g/bhp-hr or less based on certification or in-use emissions testing |
| Minimum Exhaust Temperature for Filter Regeneration | NA. Active System |
| Maximum Consecutive Minutes at Idle | NA. Active system. |
| Number of Cold Start and 30 Minute Idle Sessions Before Regeneration Required | NA. Active system. |
| Number of Hours of Operation Before Cleaning of Filter Required | NA. Active system with a flow through mesh filter. Should not require cleaning. |
| Fuel | California diesel fuel with less than or equal to 15 ppm sulfur or a biodiesel blend provided that the biodiesel portion of the blend complies with ASTM D6751, the diesel portion of the blend complies with Title 13 (CCR), sections 2281 and 2282 and the blend contains no more than 20 percent biodiesel by volume. |
| Verification Level | Level 2 Plus Verification: At least 50% reduction of PM and meets January 2009 NO2 limit. |
