The Exhaust Gas Recirculation (EGR) is an efficient, cost-effective system for reducing NOx.The high-pressure EGR loop collects part of the exhaust gases at the cylinder head outlets and re-injects them into the engine air intake. The main benefit is that NOx is reduced at the source by limiting their quantities produced during the combustion process, rather than by post-treating the exhaust gases. The EGR system emerged with the increase of HDI applications and a new European regulation to reduce pollutant emissions.
As a leader in this field, Valeo has a complete range of competitive solutions based on high and low pressure architectures for petrol and diesel engines.
