Many car owners go to the car 4S shop or maintenance plant for maintenance or detection，I 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 injection mouth and other parts，Its formation is multi -faceted。Simply speaking, Seabetwhen the engine work，Unable to burn complete 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 accumulation。When the engine is turned off，The intake valve of some cylinders cannot be completely closed，Unblied fuel is continuously evolved oxidation，Black accumulation of black accumulation in the intake pipe, especially behind the throttle。other，Carbon accumulation also comes from the fuel and gas of the fuel and lubricating rod from the crankshaft box。 The structure of carbon deposits is similar to a sponge，When a fuel injector、valve、Inlet pipes and other components after forming carbon deposits，The needlejet needle 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，resulting in poor engine work，Speed instability、Acceleration bad、 Tail Qi exceeds the standard、Abnormal phenomena such as increased fuel consumption。At the same time，Carbon deposits 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 the sound of knocking cylinder，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 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 the carbon accumulation，Choose a regular and guaranteed gas station to add fuel。
