===''EXHAUST GAS RECIRCULATION (EGR) SYSTEM''===
EGR system reduces oxides of nitrogen (NOX) emissions by recirculating exhaust gases through EGR valve into intake manifold and back to combustion chambers. System is composed of EGR valve, Constant Vacuum Control (CVC) valve and EGR control solenoid valve. EGR control solenoid valve is controlled by ECM, which analyzes input signals from EGR valve lift sensor and various sensors to provide optimum EGR flow. EGR flow is cut when combustion gas temperatures are low (when the engine emits a relatively low NOX emission) to ensure good colddriveability.
When opened, EGR valve circulates exhaust gas through intake manifold and back into combustion chamber to be reburned, resulting in reduced combustion chamber temperature. Lower temperature reduces oxides of nitrogen (NOX) and helps to control spark knock.
When ECM determines it is necessary to recirculate exhaust gases, it grounds EGR control solenoid valve, regulating vacuum controlling EGR valve. By regulating vacuum to EGR valve, EGR flow is adjusted for optimum control of NOX emission.
