Where should the catalytic converter be located?

The catalytic converter should be located close to the engine to ensure it operates efficiently. The primary function of the catalytic converter is to reduce harmful emissions produced during combustion by promoting chemical reactions that convert pollutants into less harmful substances. For these reactions to occur effectively, the catalytic converter needs to reach its optimal operating temperature quickly.

When positioned near the engine, the catalytic converter can utilize the heat generated by the exhaust gases immediately after combustion, allowing it to warm up faster and start performing its emissions-reducing functions. If it were placed farther away from the engine, the time it takes to reach the necessary temperature could be increased, leading to higher emissions during the initial period after starting the vehicle.

In addition, having the catalytic converter close to the engine helps with the overall design and flow of the vehicle's exhaust system, ensuring that exhaust gases pass through the converter efficiently.
