Introduction: Taiyuan automobile repair which good "analysis of the causes of the engine flameout automobile"

   Asphaltene in the above 300 ℃, differentiate into substance of coke and gas, so the asphaltenes in soluble pectin into the combustion chamber and gasoline combustion together, will be in the inlet valve, piston, piston ring groove, the combustion chamber, the spark plug and other parts constitute a lot of solid carbon.

   No soluble oil gum also known as deposit, it and fuel to vehicle fuel tank, will adhere to the fuel filter, infarction filter media.

   And according to the relevant part of the computation, glial, asphaltene content in petroleum, China's first oil, containing 10 percent to 40 of resin and asphaltene.

   The engine itself is the problem, because the fuel in the engine is capable of incomplete combustion, the engine, fuel or into the oil chamber can not be one hundred percent combustion, local oil unburned in the catalytic effect of Gaoping and oxygen to form colloidal hydrochloric acid and resin shaped, adhesion in part on the surface, followed by high temperature effect is further condensed into inclusion of asphaltene and oil quality coke and other complex, the so-called carbon.

   And every time when the engine stopped, because the combustion chamber temperature decreased sharply, residual fuel injector orifice droplet cannot completely evaporated, will be on the air entering the cylinder in the miscellaneous grains occurs adsorption, causing formation of carbon deposit on the orifice.

  The engine will also present the gas channeling phenomenon, namely combustion pressure in the air chamber after inclusion crack channeling between piston ring and cylinder wall into the crankcase.

  Blowby gas crankcase on the one hand the oil formation erosion make its transformation, all kinds of impurity carried on the other hand, the gas in the oil increased constitute "sludge", "oil" will accumulate, attached to the smooth road oil, oil pump screen, an oil flow congestion; the accumulation in the piston ring groove carbon deposits in the combustion chamber, a high temperature effect.
