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

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.
