The effect of CVS test parameters other than temperature on exhaust emissions was determined. Dynamometer inertia weight, road load horsepower, vehicle engine tune adjustments and smoothing the emission test driving schedule parameters were evaluated. Actual vehicle road load horsepower was measured by coast-down time and engine manifold vacuum. Tests were performed on 50 1968 through 1975 model year vehicles. 1975 and Modified 1972 Federal Test Procedures were used. Observed differences in exhaust emission and fuel economy test results were tested for statistical significance.
