The Monocar hydrocarbon device was evaluated. This Monocar system is an air bleed device combined with distributor modifications which partially eliminate vacuum advance. The vehicle used to evaluate the Monocar system was a 1971 Ford Galaxie powered by a 351 CID engine with a two barrel carburetor and an automatic transmission. This vehicle was converted to the configuration manufactured and sold in Mexico. This involved replacing the intake manifold and carburetor with a four barrel induction system, changing the distributor and changing the spark plugs. Additional baseline tests were run to compare the control effectiveness of the Monocar system on an uncontrolled system to the control effectiveness of the Ford motor low emission engine calibration. The 1975-76 Federal Test Procedure was used to determine emission levels. Results indicate that the Monocar HC system is an effective control method for lowering exhaust emissions from uncontrolled vehicles with minor fuel consumption penalty. It is not however as effective as the recalibrated carburetors and ignition system developed by the auto manufacturers.
