Abstract

This report reviews the performance of the 201350N precious metal diesel oxidation catalyst (DOC) and closed crankcase ventilation (CCV) system, consisting of the Cummins coalescer breather CV5061200 and crankcase depression regulator (CDR) valve 395587500, submitted for testing by Cummins Emission Solutions & Cummins Filtration (Cummins). Environmental technology verification (ETV) testing of this technology was conducted January 10-12, 2007, during a series of tests by Southwest Research Institute (SwRI), under contract with the Air Pollution Control Technology Verification Center (APCT Center). The APCT Center is operated by RTI International (RTI)† in partnership with the U.S. Environmental Protection Agency’s (EPA) ETV program. The objective of the APCT Center and the ETV program is to verify, with high-quality data, the performance of air pollution control technologies, including those designed to control air emissions from diesel engines. With the assistance of a technical panel of experts assembled for the purpose, RTI has established the APCT Center program area specifically 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 the Cummins DOC+CCV technology. To determine these effects, emissions results from a heavy-duty highway diesel engine were compared to emissions results obtained operating the same engine with the same fuel, but with the DOC+CCV technology installed. The specific test/quality assurance (QA) plan addendum for the ETV test of the technology submitted by Cummins was developed and approved in November 2006.2 The goal of the test was to measure the emissions control performance of the DOC+CCV technology and its emissions reduction relative to an uncontrolled engine.
