What is EGR?
Exhaust Gas Recirculation (EGR) is an efficient, cost-effective system for reducing nitrogen oxide (NOx). The high-pressure EGR loop collects exhaust gases at the cylinder head outlet and re-injects them into the engine air intake. NOx is reduced at the source by limiting the quantity produced during the combustion process, rather than by post-treating the exhaust gases.
The EGR system emerged due to the increase of High-Pressure Direct Injection (HDI) applications and new European regulations on pollutant emissions. Today, almost all European diesel engines are equipped with an EGR system.
