What is the purpose of the EGR Tube,EGR Vacuum Solenoid and EGR Valve in automotive engines?

The EGR system is used in automotive engines to reduce NOx emissions and works by diluting the air/fuel charge with exhaust gas, lowering the combustion temperature. The amount of EGR needed depends on engine geometry and conditions, determined through testing. Too much or too little EGR flow can cause engine issues. The EGR valve and pipe can be removed and installed following procedures, and the control solenoid can be replaced.

Cadillac Eldorado EGR Valve

The EGR Valve in Cadillac Eldorado cars helps in regulating the re-circulation of the exhaust back into the chamber, thus, lowering air pollution. One of these is the techniques of using water injection and exhaust gas recirculation which is common in the petrol and diesel engines to reduce the peak temperatures that result in the formation of NOx. Subsequently, EGR technology developed from initial orifice jets placing near the exhaust manifold to high quality valves regulated by engine conditions. In modern systems the flow of EGR is regulated by the load of an engine, which enhances the emissions standards. The EGR valve is located in Eldorado vehicles with intake gases of 5-15% to optimize efficiency while controlling emissions of gases; however, carbon deposit clogs the valve hence needs maintenance.

Each OEM Cadillac Eldorado EGR Valve we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
