Development of a Bench Procedure for Evaluating the Effectiveness of Dispersant -- Detergent Gasoline Additives. Phase I.
Abstract
The report covers work undertaken to develop a laboratory bench procedure for the evaluation of dispersant-detergent gasoline additive effectiveness in controlling and/or inhibiting engine intake systems deposition. A full-size evaluation procedure was selected for use as a baseline tool and a generator of deposits and deposit-causing precursors. This procedure accelerates carburetor throat and intake system deposits by recycling the crankcase off-gases back into the intake system via the main carburetor air stream. The studies to date have shown that: inorganic acids in the off-gas react with the fuel to form carburetor throat deposits, and inorganic acid precursors can be easily generated in the laboratory, eliminating the need for the engine-combustion process.
