The catalytic converter is a device placed in the exhaust pipe, which converts hydrocarbons, carbon monoxide, and NO x into less harmful gases by using a combination of platinum, palladium and rhodium as catalysts. [16] There are two types of catalytic converter, a two-way and a three-way converter.
During engine idle, brief but periodic negative pressure pulses in the exhaust system draw air through the aspirator valve and into the exhaust stream at the catalytic converter. This system, marketed as Pulse Air, was used by American Motors, Chrysler, and other manufacturers beginning in the 1970s. The aspirator provided advantages in cost ...
