What are the correct ways to clean up the carbon deposit in the car?

Carbon deposition includes two concepts. One concept is the fuel produced by the fuel produced by the engine at high temperature during its operation. The second concept is carbon deposition in EDM, which should be avoided as much as possible, especially in precision die processing, which is fatal. Provide data near # Pupu Combustion # to support primary carbon cleaning of automobiles.

Here we discuss the first concept, the carbon deposit of the engine.

When the engine piston moves downward, the mixture of gasoline and air is inserted into the cylinder, then the piston moves upward, then the oil and gas are pressed into highly combustible gas, and finally the spark plug is ignited. This powerful explosive force drives the piston, so the engine generates power. The source of power mixture must enter the combustion chamber through the intake valve; A small amount of gasoline will be connected to the intake valve. When it meets the high temperature of the engine, it can't burn the complete hydrocarbons and paraffin in gasoline, and it will be burned into rubber carbon when it collapses. If the injector is inverted, the sprayed gasoline will be uneven, and the gasoline and air will be mixed unevenly, which will increase the amount of gasoline condensed into the intake valve. To make matters worse, rubber charcoal absorbs gasoline, so this charcoal will absorb gasoline, and then burn the absorbed gasoline into thicker charcoal, thicker charcoal, and absorb more gasoline. Such a vicious circle is that there is too much carbon deposited in the intake valve, which makes the engine unable to run.

Unsaturated hydrocarbons and GBSID are the main raw materials of carbon in gasoline. The olefins and aromatics in five kinds of gasoline in China are obviously higher than the international level, so it is more likely to produce carbon. Although the olefin content of five kinds of gasoline in China has decreased from 28% to 24% (the aromatic hydrocarbon standard has not changed), it is still far higher than the international level (especially in the United States). With so many excellent engines, China will have water and soil. The most typical engine is Honda's "Earth Dream" series. When I arrived in China, it was called "coal mining dream", and its owner was born. Second, the innate factors of gasoline engine working mode.

Mainstream gasoline engines are mainly divided into manifold injection and in-cylinder direct injection, and carbon generation is distinguished.
