Clean Diesel Technologies announced that the California Air Resources Board has issued an executive order allowing CDTi to advertise, sell and install its Purifilter EGR diesel particulate filter
while CDTi is waiting for a full and final verification from CARB.

Accordingly, CDTi is now taking orders for this technology.

Purifilter EGR, a passively regenerating DPF, provides exceptional filtration and regeneration efficiency for the removal of particulate matter, claims the company.

The product addresses a number of exhaust-gas-recirculation-equipped heavy-duty trucks currently subject to the California Truck and Bus Regulation, which requires diesel trucks and buses that operate in California to be upgraded to reduce emissions by various deadlines.

With a full verification process currently under way by both CARB and the Environmental Protection Agency, receipt of this order enables CDTi to begin selling Purifilter EGR to fleet operators while final verification is pending. CDTi is offering the Purifilter EGR under the CARB After-Market Add-On Parts Exemption covered by the executive order.
