Effects of oxygenated fuel containing methanol or methyl tertiary-butyl ether (MTBE) on the sludge formation were examined by using a laboratory-scale sludge simulator. The sludge formation is found to decrease with the concentration of oxygenated compounds in gasoline. Gas chromatograph analysis shows that the sludge formation is closely related with composition of hydrocarbon is pyrolysis products. And chemical interaction between oxygenated compounds and hydrocarbons is discussed.
