EGR System: Description
The exhaust gas recirculation system is designed to control formation of NOx emissions. This is done by introducing some of the exhaust gas back into the combustion chamber. The exhaust gases are lower in temperature than the combustion flame. By reducing combustion chamber temperatures, NOx formation is reduced.
The Fuego and Sportwagon non-turbo systems include thermo valve, vacuum reservoir, differential pressure switch, EGR valve solenoid and EGR valve. See Figure .
The Fuego Turbo system includes an EGR valve, solenoid valve, 5th gear transmission switch, coolant temperature switch, pressure surge valve and vacuum reservoir. See Figure .
