Exhaust gas recirculation cooler for Volv o Cooling parts EGR cooler 36003021​

Product Description:

 
EGR cooler assembly
OE NO.:  36003021

Applicable vehicle type: For VO LVO

The automotive EGR cooler (Exhaust Gas Recirculation Cooler) is a core component of the exhaust gas recirculation system, positioned between the engine exhaust manifold and the intake manifold. Its function is to cool and reduce the temperature of the exhaust gases recirculated back into the cylinders, thereby lowering combustion temperatures within the cylinders and reducing the formation of nitrogen oxides (NOₓ). It is a key device enabling vehicles to meet emission regulations such as China IV, China V, China VI, Euro IV, and Euro V, and is widely used in diesel engines and certain large-displacement petrol engine models.

Core Functions:

• Exhaust Gas Temperature Reduction: Cools high-temperature exhaust gases (approximately 500-600°C) introduced from the exhaust pipe to 150-250°C. This prevents excessive combustion temperatures caused by direct high-temperature exhaust entry into cylinders and protects the intake manifold from thermal damage.
• Optimising combustion efficiency: The cooled exhaust entering the cylinder dilutes the air-fuel mixture concentration and slows combustion speed. This reduces nitrogen oxide emissions, minimises engine knock risks, and enhances fuel economy.
• Meeting emission regulations: By precisely controlling exhaust gas recirculation temperature and ratio, it helps engines achieve stringent emission limits, serving as an essential safeguard for vehicles to pass annual inspections and ensure compliant sales.
• Protecting engine components: Prevents thermal shock damage to intake valves, pistons, cylinder heads and other components from high-temperature exhaust gases, thereby extending engine service life.
