An evaluation was initiated on an exhaust gas recirculation retrofit device developed by Vor-Air, Inc. This system was basically a simple exhaust gas recirculation device with the addition of an air-bleed system. Exhaust was picked up from the exhaust manifold and piped through a control valve to the PCV line for introduction into the intake manifold. In addition, filtered air from the air cleaner housing was allowed to mix with the EGR flow into the PCV line. Baseline and device tests were performed according to the 1972 Federal emission test procedure, using a 1970 Plymouth Valiant equipped with an automatic transmission and 225 CID six-cylinder engine.
