Many car owners go to car 4S stores or repair shops for maintenance or inspection，I often hear maintenance consultants say that the car should be cleaned of carbon deposits，Carbon deposits refer to the accumulation on the valves of the engine、Intake duct、Cylinder wall、Piston、Carbon and vinyl substances in fuel injection seabet mynozzles and other parts，Its formation is multifaceted。Simply speaking, when the engine is working，Hydrocarbons in gasoline that cannot be completely burned、Paraffin、Glutinum attached to the valve、On piston and cylinder walls，Over time, more and more wax and colloid accumulate, forming carbon deposits。When the engine stalls，The intake valve of some cylinders cannot be fully closed，Unburned fuel continues to evaporate and oxidize，It will produce black carbon deposits in the intake pipe, especially behind the throttle。In addition，The carbon deposit also comes from the oil vapor in the crankcase ventilation and the oil lubrication rod。 The structure of carbon deposits is similar to a sponge，As a fuel injector、Valve、After carbon deposits form on air intake pipes and other components，The injector needle valve will be stuck or clogged，Part of the fuel injected into the cylinder will also be adsorbed，Thinner the concentration of the mixture that actually enters the cylinder，Resulting in poor engine operation，Unsteady idle speed occurs、Bad acceleration、 Exhaust gas exceeds the standard、Abnormal phenomena such as increased fuel consumption。simultaneously，Carbon deposits in the cylinder will reduce the combustion chamber volume，Increased compression ratio，Easy to cause detonation。In addition，The hardness of carbon deposit is higher，seabet ioIn severe cases, the movement of the valve and piston can cause interference，The impact produces a knocking sound，Even strain the cylinder wall。
The generation of carbon deposits is inevitable，For car owners，You can reduce the generation of carbon deposits by starting from daily driving habits and vehicle maintenance，For example:
1. Reduce driving on congested urban roads，Let the engine run at medium and high speeds as much as possible，Enable full combustion of gasoline，Thus reducing carbon deposits。
2. Add fuel additives appropriately，Its main function is to promote the sulfur in gasoline by relying on the ingredients in the formula and additives、Complete combustion of harmful substances such as colloids，Not only improves engine power，And forms a protective film on the metal surface，Inhibit the generation of carbon deposits。
3. Fill with high-quality gasoline，The composition of gasoline is complex，Poor fuel quality will accelerate the formation of carbon deposits，Choose regular and guaranteed gas stations to refill fuel。
