Valeo EGR Exchanger Cooling & Air Management for Passenger car

EGR Exchanger

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. The main benefit is that NOx is reduced at the source by limiting the quantities produced during the combustion process, rather than by post-treating the exhaust gases.
 

What is an EGR Exchanger?

An EGR exchanger, also known as an EGR cooler or EGR heat exchanger, cools exhaust gas prior to it being reintroduced into the engine. The EGR exchanger is installed in the EGR circuit and can be located upstream or downstream of the EGR valve.

By cooling the gas, the combustion temperature is reduced which also reduces the quantity of NOx particles as they are formed at high temperatures.
