2. Problems with the fuel itself
Because fuel is being stored and transported, the gums may be oxidized by heat. glia is a very viscous fluid or a semi-solid gel, the gum itself is soluble in fuel, but when the colloid is oxidized by heat, it will turn into asphaltenes, become Insoluble fuel of Oleoresin.
When asphaltenes are above 300 ℃, they will decompose into coke-like substances and gases, so asphaltenes burn with gasoline after they enter the combustion chamber, they will form a lot of hard carbon deposits on the intake valve, piston top, piston ring groove, combustion chamber, spark plug, etc.
Insoluble oil glue also is known as sediment, after it is added to the fuel tank of the car with the fuel, it will stick to the fuel filter, Clogged filter media.
