What are the consequences of poor-quality gasoline?
1 Answers
Poor-quality gasoline can lead to a loss of vehicle power in mild cases, while in severe cases, it may cause engine knocking, cylinder scoring, and ultimately engine failure. Gasoline is produced by refining various components such as straight-run gasoline, catalytic cracking gasoline, and catalytic reforming gasoline derived from petroleum refining, which are then blended with high-octane components. It is primarily used as fuel for spark-ignition internal combustion engines in automobiles. At room temperature, gasoline is a colorless to light-yellow, highly mobile liquid that is difficult to dissolve in water and highly flammable. The octane rating of gasoline measures its resistance to knocking in specific gasoline mixtures. Based on different octane ratings, gasoline is classified into several grades. Chemical additives are often mixed into gasoline to enhance chemical stability and other performance characteristics, control corrosiveness, and maintain the cleanliness of the fuel system.
