What percentage of particulate matter can be reduced by using DOCs?

• A. 10 to 20%
• B. 20 to 50%
• C. 50 to 70%
• D. 70 to 90%

Answer: (B)

Using Diesel Oxidation Catalysts (DOCs) can significantly reduce particulate matter emissions from diesel engines. The reduction percentage attributed to DOCs typically falls within the range of 20 to 50%. These catalysts work by oxidizing carbon monoxide and unburned hydrocarbons, resulting in a decrease in the amount of particulate matter emitted into the atmosphere. While higher efficiency reductions are possible with other technology options or systems, DOCs specifically have been demonstrated to achieve this level of effectiveness, which is why the percentage of 20 to 50% is considered accurate for their performance. This value reflects the capabilities of DOCs in real-world applications, emphasizing their role in emissions control strategies aimed at improving air quality.
