Types of Catalytic Converters
#1. Diesel Converter
These types of catalytic converters are common in diesel and other compression ignition engines. In most cases, they are efficient and are responsible for reducing s the soot from the exhaust gasses. Further, diesel oxidation catalyst is the most commonly available form of diesel catalytic converters. They utilize oxygen as a catalyst to convert carbon monoxide to less toxic carbon dioxide. As a result, the converter is capable s of eliminating visible carbon particles (soot) as well as diesel odor. However, the catalyst is not active for action on oxides of nitrogen.
#2. Two-Way Converter
Nowadays, two-way converters are mainly in use by diesel engines. Their usage on gas engine was abandoned since 1981 due to inability move oxides of emission from exhaust emissions. The mode of action of theses converters is by use of oxygen to oxidize carbon monoxides to carbon dioxide. Also, oxygen is used toss convert unburned hydrocarbons into carbon dioxide and water. Basically, two-ways converters have two reactions.
#3. Three-way Converters
As the name suggest, these converters undergo a series of three reactions involving reductions and oxidation. They are commonly used in gas powered engines to eliminate harmful gasses. The first reaction involves reduction of oxides of nitrogen into oxygen and nitrogen. The second one is oxidation of carbon monoxide to carbon dioxide while the last one is oxidizing unburned hydrocarbons to carbon dioxide.
