2006 Lexus GS300 “How many catalytic converters are in a 2006 Lexus GS300?” you ask? Well, that depends on what year the vehicle was built. Many federal and state laws have been passed to reduce emissions from vehicles. One way manufacturers meet these laws is by installing emission control devices such as catalytic converters. The US Environmental Protection Agency [EPA] has this [catalytic converter article] which discusses emission requirements and explains why so rules exist for OEM equipment.
There are Single three-way catalytic converter that consists of three sections:
-An oxygen storage section, which stores oxygen from the exhaust stream until it can be released in the engine’s combustion process to reduce emissions. This is also known as an air pump or adsorptive converter because it adsorbs and holds the oxygen.
-A reduction section, which uses a reductant such as ammonia to break down (“reduce”) hydrocarbons and carbon monoxide into water vapor and carbon dioxide so they can be released into the atmosphere. The ammonia passes through a catalyst where it is heated up and breaks down these harmful pollutants. The ammonia then goes back to the oxidation chamber where its cycle begins again. However, during this process some of the ammonia gets used up reducing the amount of reductant available to convert pollutants.
– An oxidation section, which oxidizes the carbon monoxide and hydrocarbons into water vapor and carbon dioxide.
