Egr

EGR spare parts and their function in the exhaust system

In this catalog, we offer components for Exhaust Gas Recirculation systems, essential for the proper operation of industrial vehicles. The EGR valve is a critical component that helps reduce combustion temperatures and lower nitrogen oxide emissions, ensuring that the truck or heavy-duty vehicle complies with current environmental regulations.

This section is aimed at workshop professionals, fleet managers, and owners who require reliable spare parts for repairs or preventive maintenance. Here you will find valves and coolers designed to integrate effectively with the rest of the exhaust line, ensuring optimal engine performance under demanding working conditions.

Key aspects when choosing the right EGR valve

• Identify the original (OEM) reference of the replaced part to ensure mechanical and electronic compatibility.
• Verify the vehicle’s emission standard (Euro 4, Euro 5, or Euro 6), as systems vary significantly depending on this regulation.
• Check the type of actuation of the valve, distinguishing between pneumatic and electric systems.
• Review whether the component includes the cooler or if it is only the valve body.
• Confirm whether the replacement includes the necessary mounting gaskets to ensure proper sealing after installation.

Frequently asked questions

What is the function of the EGR in a heavy-duty vehicle?

Its main function is to reintroduce part of the exhaust gases into the engine intake. This reduces combustion chamber temperature and limits the formation of nitrogen oxides (NOx), which is essential for passing technical inspections and complying with anti-pollution regulations.

What are the symptoms of a faulty EGR valve?

The most common issues include noticeable engine power loss, black smoke from the exhaust, jerking during driving, or the activation of the engine warning light on the vehicle’s dashboard.

Is it better to clean the valve or replace it with a new one?

Cleaning can be effective if the issue is only carbon buildup. However, if there are failures in the electric solenoid, leaks in the cooler, or wear in the opening mechanism, replacement is necessary to ensure long-term system reliability.

How can I ensure compatibility of the replacement part?

The safest way to avoid errors is to search for the replacement using the reference code engraved on the old part. You can also consult the vehicle’s technical sheet to verify the engine code and year of manufacture before selecting the product.
