| Abstract |
Particulate and sulfuric acid emissions were studied in the exhaust of a production 1970 Chevrolet 350 CID 2-barrel engine; with and without a pelleted and monolithic oxidation catalyst treating the exhaust. Particulates were collected at various points along a specially-constructed exhaust system. Total mass and the sulfuric acid content of the particulates were measured, as well as the percent conversion of fuel sulfur content into emitted sulfuric acid under variations in the following operating conditions: Cyclic and constant engine speeds; catalyst temperatures; fuel sulfur contents; catalyst exhaust flow rates; secondary air flows; and, air-fuel ratios. It was found that the total mass and sulfuric acid content of the particulates, as well as % conversion of fuel sulfur content depend mostly on engine speed, catalyst temperature, and fuel-sulfur content. |
