Abstract A confirmatory evaluation was conducted on a retrofit system for which previous test data indicated a significant reduction in hydrocarbon and carbon monoxide emissions. The Landrum system employs the replacement of stock idle mixture screws with hollow bleed-type screws which allow gasoline to enter mixing with air. For this test the stock idle screws were removed from a 1971 Ford, 351 CID engine with automatic transmission. The Landrum screws were installed with the associated heating element. Testing of the vehicle both baseline and device equipped was done in accordance with the 1972 and 1975 Federal Test Procedures. Fuel consumption has been calculated from exhaust emissions. The test data indicates that the Landrum system appears to reduce hydrocarbon by 10% and carbon monoxide by 15%. A 7% fuel consumption penalty is associated with the system. While these reductions appear small, this was partially due to careful adjustment of the baseline vehicle to a lean idle setting.
