Car not speeding up when pressing the gas? Smell sulfur?

It might be time to check your catalytic converter. Damaged or clogged catalytic converters are dangerous and may cause your engine to fail.

Catalytic converters prevent the exhaust system of a vehicle from releasing dangerous gases like carbon monoxide, hydrocarbons and nitrogen oxide into the atmosphere. A damaged oxygen sensor can lead to the catalytic converter operating less efficiently and reducing its lifespan. If there is not enough oxygen, the harmful gases will fail to dissipate, while too much oxygen can cause the converter to overheat and fail. The technicians at West End Auto will make sure your catalytic converter is functioning as it should be.

Catalytic Converter Basics

Positioned on the underside of your vehicle, the catalytic converter helps clean up vehicle emissions before expelling them into the environment. Catalytic converters contain honeycomb-like
structures coated with platinum and palladium that help minimize the harmful effects of carbon monoxide, hydrocarbons, and nitrogen oxide produced by your vehicle’s engine.

These harmful gases pass through two stages: the reduction catalyst stage and the oxidation catalyst stage. During the reduction catalyst stage, nitrogen oxide is converted into oxygen and nitrogen gases while carbon monoxide and hydrocarbon is oxidized in the oxidation catalyst stage.

The catalytic converter also relies on the oxygen sensor to detect the correct level of oxygen introduced in the oxidation catalyst stage. Routine exhaust system maintenance can help ensure your catalytic converter is always working optimally and reduce the likelihood of it releasing harmful and often deadly chemicals into the environment, or into the cabin of your vehicle.
