Exhaust Gas Recirculating Valve
This system is used on 1972-73 Type I with automatic stick shift or 1972-73 Type III with automatic transmission only. System is designed to reduce NOx emissions. Exhaust gas which has been cleaned and cooled (in cyclone filter) is recirculated into intake system, during partial load operation.
NOTE:
System does not operate during periods of idle, wide open throttle, third gear operation, or when intake air temperature is below 65°F.
Components of system are: An air intake distributor, exhaust gas recirculating valve, cyclone filter and container, throttle valve switch, and thermo switch, and transmission oil pressure switch.
