The three-way catalytic converter

This course covers the learning outcomes and goals of understanding exhaust pollutants, the three-way catalytic converter, exhaust emission characteristics, chemical reactions for CO, hydrocarbons, and NO removal, the role of CeO2, catalyst deterioration due to thermal effects and poisons like phosphorus and sulfur. The course teaches the composition and performance of the catalyst, along with the chemical reactions involved. The teaching method includes theoretical explanations and summaries. The intended audience for this course includes students and professionals interested in automotive engineering, environmental science, or catalytic converter technology.
