Clean Diesel Technologies Inc. (CDTi) has received an expanded verification from the California Air Resources Board (CARB) for its Purifilter exhaust gas recirculation (EGR) emission reduction system.
CDTi says the verification presents additional market opportunity attributable to a greater range of vehicle applications, such as those operating with lighter loads and lower exhaust temperatures.
The Purifilter EGR, featuring the company's proprietary MPC technology, is a passively regenerating diesel particulate filter that provides filtration and regeneration efficiency for the removal of particulate matter from EGR-equipped heavy-duty diesel on-road engines.
Ian MacDonald, vice president of sales and marketing, says that with the expanded verification, the company “can assist fleet managers to more broadly retrofit their vehicles to reduce harmful emissions.” He adds that the system “covers the bulk of 2004-2006 engines, which are expected to comprise a large portion of the retrofit engines subject to CARB's Truck and Bus Regulation.”
The system is already verified by both the U.S. Environmental Protection Agency (EPA) and CARB for on-road vehicle applications.
