Emission tests were run on the Frantz Vapor Injector retrofit system. This device was a vapor injector system which added a mixture of air and a vaporized chemical to the positive crankcase ventilation line with the amount of vapor-air mixture dependent on the manifold vacuum. The device was tested on a 1968 Ford Falcon equipped with a 200 cu. in. six-cylinder engine and manual transmission. The vehicle was tested under three differing conditions, using two different test procedures. The first four tests were conducted with the vapor injector as installed by Frantz; two using the 1972 Federal emission test procedure (LA4), and two using the 1971 Federal emission test procedure (7-mode). One 7-mode and one LA4 were run after removing the vapor injector.
