Abstract |
Data submitted to the Environmental Protection Agency Motor Vehicle Emission Laboratory indicated that an air-bleed device known as the Landrum Mini-Carb could cause a reduction in exhaust emissions and improve fuel economy. Consequently, an EPA confirmatory test program was set up to investigate the effects of the Landrum Mini-Carbs on exhaust emissions and fuel economy. The Mini-Carbs appreciably reduced carbon monoxide emissions from the test vehicle. A small decrease in unburned hydrocarbon emissions and a small increase in oxide of nitrogen emissions also occurred. The effect of the Mini-Carbs on fuel economy was not significant. Ingestion of poorly filtered air through the Mini-Carbs may have an adverse effect on the engine and carburetor durability. |
