How Does Exhaust Temperature Affect Catalyst Performance?
The performance of a catalyst is heavily influenced by exhaust temperature. Catalysts typically have an optimal temperature window, known as the light-off temperature, where their activity begins to effectively convert pollutants. If the exhaust temperature is too low, the catalyst may not reach its optimal operating condition, leading to inefficient conversion. Conversely, excessively high temperatures can result in catalyst degradation or sintering, reducing its effectiveness and lifespan.
