A catalyst is an emissions control component integrated into the exhaust system of internal combustion equipment. It works by facilitating a chemical reaction that converts harmful exhaust gases into less harmful byproducts before they are released into the atmosphere. When the catalyst degrades or becomes blocked, exhaust backpressure can increase, engine performance may suffer, and the machine may fall out of compliance with emissions regulations — making timely replacement important for both performance and regulatory reasons.
