Clean Diesel Technologies, Inc., Fuel-Borne Catalyst with CleanAir System's Diesel Oxidation Catalyst
This report reviews the performance of the Clean Diesel Technologies platinum/cerium fuelborne catalyst used with CleanAir System’s Diesel Oxidation Catalyst (Model CPD0950). Environmental Technology Verification (ETV) testing of this technology was conducted during a series of tests in July 2003 by Southwest Research Institute (SwRI) under contract with the Air Pollution Control Technology Verification Center (APCTVC). The objective of the APCTVC and the ETV Program is to verify, with high data quality, the performance of air pollution control technologies. Control of air emissions from diesel engines is within the scope of the APCTVC. An APCTVC program area was designed by Research Triangle Institute (RTI) and a technical panel of experts to evaluate the performance of diesel exhaust catalysts, particulate filters, and engine modification control technologies for mobile diesel engines. Based on the activities of this technical panel, the Generic Verification Protocol for Diesel Exhaust Catalysts, Particulate Filters, and Engine Modification Control Technologies for Highway and Nonroad Use Diesel Engines1 was developed. This protocol was chosen as the best guide to verify the immediate performance effects of Clean Diesel Technologies’ technology versus a protocol developed for fuel modifications. The verified technology incorporates both a catalyst added to the fuel and a device (the diesel oxidation catalyst). The specific test/quality assurance plan addendum for the ETV test of the technology submitted by Clean Diesel Technologies, Inc. was developed and approved on June 10, 2003.2 The goal of the test was to measure the emissions control performance of the technology system and its emissions reduction relative to an uncontrolled engine.
