Abstract
An evaluation was initiated of a modified emission control system. The Berg System performs two functions. The primary effect is that of bleeding additional air to the intake manifold, thus leaning combustion. The second function is to supply fuel vapors from the gasoline tank to the intake manifold. The test vehicle was a 1963 Galaxie. Three different configurations of the Berg System were evaluated. Baseline or stock vehicle testing was conducted before, during, and after the device testing. All tests were performed according to the 1972 Federal Emission Test Procedure. The Berg System is a simple air bleed device. Depending on the quantity of bleed air, the system reduces hydrocarbon and carbon monoxide levels. Maximum reductions of 29% and 64% were obtained during the evaluation. Further investigation is needed to determine the proportion of in-use vehicles which would be adversely affected by this system.
