Description:Transportation sources remain the primary source of man- made hydrocarbon (HC) and carbon monoxide (CO) emis- sions. Most of the remaining HC and CO exhaust emissions from new automobiles occurs shortly after starting, before the exhaust has warmed the catalytic converter to lightoff temperature. Precision Combustion, Inc. is developing a low cost, fast lightoff, electrically heated metal monolith catalytic converter directed towards eliminating this gap in emissions control while improving conversion effectiveness and long term durability.
Phase I laboratory configuration testing showed that a low power sufficiently rapid heat-up can be achieved for full conversion immediately after engine start-up. CO and ad- justed non-methane hydrocarbon conversions were in excess of 99%. Preliminary automotive and durability testing was successful.
Phase II will be directed towards system development, involving design, construction and testing of one or more commercially feasible prototypes, and culminating in Fed- eral Test Procedure (FTP) tests of an automotive prototype by the New York State Automotive Emissions Laboratory.
