THREE-WAY CATALYST SYSTEM [6 records]

Record 1 2013-05-24

English

Subject field(s)
  • Ignition Systems (Motor Vehicles)
CONT

There is clear agreement among the manufacturers that the basic emission control approach will be the closed-loop, three-way catalyst system. In addition to the catalyst, the typical system will consist of exhaust gas recirculation(EGR), air injection(pulse air in light vehicles, air pump in heavy vehicles), oxygen sensor, micro-computer, and feed-back carburator or electronic fuel injection.

The SEIA study... provides a "best estimate" of the incremental cost impact to the consumer of $200 where the currently used oxidation catalyst system is upgraded to the American closed-loop three-way reduction catalyst system, and about $400 for upgrading a vehicle with a non-catalyst system to a three-way system.

The CRC results were based on seven 1977-78 model year cars, all of which were calibrated to meet California standards. Advances in sensor technology since then may have alleviated some of the problem. If the sensor prematurely fails on a three-way catalyst system, feed-back control is lost.

THE TECHNOLOGY AND COSTS TO CONTROL AUTOMOTIVE EMISSIONS IN CANADA.... The selection of a three-way catalyst system, or more correctly, a U. S. federal emission control system, is dictated solely by production volume consideration; this system would be selected whenever costs for development, certification, and compliance of a unique Canadian system exceed the costs of a U. S. federal system.

The Technology and Costs to Control Automotive Emissions in Canada.... The authors’ best estimate of the incremental cost impact to the consumer of adopting the proposed standards is about $200 for upgrading the current oxidation catalyst system to a three-way and about $400 for upgrading the current non-catalyst system to a three-way system.
