| Abstract |
This project sought to validate an engine dynamometer test schedule for additive effects previously used in Dow and Bu Mines programs. Previous problems with vehicle-to-engine dynamometer comparability were solved by the use of a Clayton power absorption unit and a fixed flywheel as an inertia simulator. Thus, adequate road simulation was achieved. Numerous analytical techniques were developed including analysis for SO2, H2S, COS, methyl and ethyl mercaptan, ammonia, N,N-dimethylnitrosamine, hydrocarbon distribution, and sulfate. No additive-derived products were found in the study of two commercial additive packages with either catalyst or non-catalyst engine configurations. The mileage accumulation schedule used resulted in overly-high rates of accumulation of intake manifold deposits for both additive and base fuels. It is suggested that greater mileage accumulations over a heavier duty cycle will be necessary to detect the effects of additives on catalyst deterioration. |
