Many car owners go to the car 4S shop or repair plant for maintenance or detection，I will often hear the maintenance consultant and say that the car should be cleaned and accumulated，Carbon accumulation refers to the valve accumulated in the engine、Inlet pipe、cylinder wall、Pistons、Carbon and vinyl substances in the fuel jet mouth and other parts，Its formation seabet loginis multi -faceted。Simply speaking, when the engine work，Unable to burn completely hydrocarbons in gasoline、paraffin、Globe is attached to the valve、Pistons and cylinder walls，In the long period of time, the more wax and glue, the more accumulated the accumulation of carbon。When the engine is turned off，The valve of some cylinders cannot be completely closed，Unblied fuel is continuously evolved oxidation，It will produce black accumulation in the intake pipe, especially behind the throw door。other，Carbon accumulation also comes from the fuel and gas of the groaning of the crankshaft box and the oil。 The structure of carbon deposits is similar to a sponge，When a fuel injector、valve、Pipeline pipes and other components after forming carbon deposits，The pneeling valve will be stuck or blocked，The fuel sprayed into the cylinder will also be adsorbed，Make the mixed gas concentration that really enters the cylinder，Lead the engine's poor work，Saying instability、Acceleration bad、 Tail Qi exceeds the standard、Increased fuel consumption and other abnormal phenomena。At the same time，The accumulation of carbon in the cylinder will reduce the volume of the combustion room，Increased compression ratio，It is easy to cause explosive shock。other，High hardness of carbon deposits，In severe cases, the valve and piston seabet mymovement can cause interference，The impact generates a knock tank sound，or even strain the cylinder wall。
The production of carbon deposits is unavoidable，For the owner，You can keep your hands from daily driving habits and vehicles to reduce the production of carbon deposits，For example:
1. Reduce driving in urban congested roads，Make the engine as much as possible as possible to operate at medium and high speed，Makes gasoline fully burn，to reduce carbon deposits。
2. Properly add fuel additives，Its main function is to promote sulfur in gasoline in the formula and the ingredients in the additive、Plastic substances and other harmful substances are completely burned，Not only improves the engine power，and form a protective film on the metal surface，Inhibit the production of carbon deposits。
3. Inject high -quality gasoline，The composition of gasoline is complicated，If the quality of fuel is not good, it will speed up carbon accumulation，Select a regular and guaranteed gas station to add fuel。
