Ultimate Guide to Understanding Catalytic Converters

AMJ Auto Repair • July 1, 2023

Catalytic converters are an essential component of modern vehicles. These devices have improved air quality. If you are experiencing issues with your catalytic converter, knowing what is happening is crucial.

What is a catalytic converter?

The catalytic converter is a metal canister installed in the vehicle’s exhaust system. Its purpose is to convert toxic gases emitted by the engine into less harmful gases before they are released into the environment. The converter is designed to last the life of your vehicle, but factors such as driving conditions, maintenance, and defective components can cause their lifespan to be reduced. Faulty catalytic converters can cause harm to the environment and also lead to reduced performance and efficiency of your engine. Thus, keeping them in good shape and checking their condition is crucial.

Why does a catalytic converter fail?

Catalytic converters fail due to internal clogging, overheating, or general wear and tear. Clogging can occur when unburned fuel or engine coolant accumulates, blocking the channels and allowing exhaust gases to pass through. Overheating can happen when a misfiring engine causes unburned fuel to enter the converter, and excess fuel causes the converter to overheat. Time and use can cause catalytic converters to degrade and stop functioning correctly.

Catalytic converters reduce emissions, improve air quality, and keep your car running smoothly. Understanding how these devices work and how to maintain them can prevent costly repairs and ensure optimal vehicle performance. Contact a qualified mechanic or auto repair shop to identify and fix issues before they become more significant.
