Where is the EGR located on an engine?
The EGR is usually located on the inlet manifold of the engine, although sometimes it can be located lower down near the exhaust manifold. It operates by recirculating exhaust gas back into the engine through the intake. This gas is cooler than the combustion temperature inside the cylinder, which reduces the production of oxides of nitrogen.
