Ford Focus Catalytic Converter

The catalytic converter is an essential component of your Ford Focus emissions system. It filters harmful pollutants from the exhaust gases before they are released into the atmosphere, helping reduce environmental pollution and ensuring your vehicle complies with emission standards.

The catalytic converter operates on a chemical principle. Exhaust gases heat the converter to a specific temperature, where harmful elements are chemically burned and converted into less toxic substances before exiting the exhaust pipe.

• Core made of ceramic monolith with honeycomb structure for gas flow
• Uses platinum, palladium, and rhodium as catalysts
• Includes an elastic intermediate layer and stainless steel shell for durability

This precise design ensures durability and effective pollutant conversion in your vehicle’s exhaust system.

The catalytic converter transforms harmful exhaust gases into safer compounds :

• Hydrocarbons are converted
• Carbon monoxide is converted
• Nitrogen oxides are converted

The end result is cleaner emissions consisting mainly of carbon dioxide, nitrogen, and water vapor.

To work effectively, the catalytic converter must reach an operating temperature of around +200°C. Sensors monitor this temperature and report data to the engine control unit (ECU) to maintain optimal performance.

• Lambda sensors measure oxygen concentration before and after the converter
• Temperature and heating sensors ensure thermal conditions are within the required range
• Typically equipped with two lambda sensors for precise control

This monitoring system ensures your vehicle’s engine runs efficiently and within environmental standards.

The most common model for petrol-powered Ford Focus vehicles is the three-way catalytic converter. This converter simultaneously converts hydrocarbons, carbon monoxide, and nitrogen oxides into less harmful substances.

Signs of a failing catalytic converter include :

• The engine light turning on (Check Engine Light)
• Reduced engine power or performance
• Increased fuel consumption due to altered air-fuel mixture
• Failing emissions tests

If you notice these symptoms, it is important to have your catalytic converter inspected and serviced promptly to avoid further engine issues.

The replacement involves :

• Removing the faulty catalytic converter by welding it out from the exhaust system
• Installing a new catalytic converter that fits the specific vehicle model
• The exhaust pipe and main line remain intact and are not replaced
• ECU may be re flashed to proper standards or fitted with sensor adjustments

This ensures your vehicle remains EPA compliant, runs efficiently, and meets legal emission standards.

Used catalytic converters should be properly recycled to recover precious metals like platinum, palladium, and rhodium, reducing environmental impact and providing resource efficiency.

• Contact authorized recycling or buy-back programs to handle used converters
• Krosfou offers a used DPF/catalytic converter buy-back service for professionals
• Never attempt to dismantle or dispose of converters yourself due to hazardous materials

Proper recycling supports environmental sustainability and aligns with industry standards.
