Dacia Logan Catalytic Converter

The catalytic converter in a Dacia Logan is a vital component of the exhaust system that transforms toxic gases into carbon dioxide and water through a redox chemical reaction. It operates with two main chemical processes: a reduction catalysis using rhodium or platinum to reduce nitrogen oxides (NOx), and an oxidation catalysis using platinum and palladium to reduce unburned hydrocarbons and carbon monoxide. The ideal operating temperature is around 420°C, which is why the catalytic converter is positioned close to the engine for efficiency.

There are two main types of catalytic converters for the Dacia Logan:

• Two-way catalytic converters, mainly used for older diesel engines.
• Three-way catalytic converters, designed for petrol engines.

The complete exhaust system also includes the front silencer, rear silencer, and the Diesel Particulate Filter (DPF) for diesel vehicles.

Signs indicating a problem with your Dacia Logan catalytic converter include:

• The "Check Engine" warning light appearing on your dashboard.
• Reduced engine power, lower top speed and slower acceleration.
• Increased fuel consumption.
• Difficulty starting the engine.
• Unusual noises coming from the catalytic converter during heavy engine use.

If these symptoms occur, it is recommended to diagnose the catalytic converter promptly.

Common replacement solutions include:

• Flame arrester replacement : A common fix involves cutting and removing the malfunctioning catalytic converter and installing a flame arrester as a replacement, secured with special clamps.
• Universal catalytic converter : A universal catalytic converter can be installed but is not recommended as it may cause noise during intensive engine operation.

Always ensure replacements meet environmental and legal standards.

The price of a Dacia Logan catalytic converter varies depending on the model. For example, the cost for a Logan MCV II 1.2 ranges between 326 and 800 CHF. Prices can differ based on the specific engine and year model.

Yes. The catalytic converter is essential to limit emissions and comply with Euro 4 and Euro 5 standards. Removing or tampering with the catalytic converter can have legal consequences and negatively affect the vehicle's durability and environmental protection.

Maintaining a functional catalytic converter ensures your vehicle meets required emission regulations.

There are illustrated manuals and step-by-step video tutorials available on automotive maintenance platforms. These provide guidance on checking and replacing the catalytic converter as well as controlling the exhaust system health.

For expert advice or professional parts, consider accessing authorized suppliers offering quality components that meet technical standards and offer warranties.

For optimal comfort, protection of your vehicle, and to save money in the long term, choose certified high-quality catalytic converters that meet or exceed manufacturer specifications and European regulations.

• Look for products made of stainless steel with high-grade monolith structures treated with rare metals.
• Prefer parts with valid warranty and solid delivery and after-sale service options.
• Ensure compatibility with your Dacia Logan's engine displacement and fuel type.

Choosing quality items helps ensure better performance, compliance, and vehicle longevity.
