Exhaust Gas RECIRCULATION System: Description

The Exhaust Gas Recirculation System (EGR) recirculates exhaust gases into combustion chamber to reduce combustion temperature. This reduction in temperature acts to reduce Nitrogen Oxide (NOx) emissions produced during the combustion process. This system consists of a balance tube, control valve, solenoid valve, thermo switch, EGR tube, vacuum hose, and a water hose.
