Description

Technical field: [0001] The invention relates to the technical field of automobile electronics, in particular to a method and device for removing carbon deposits in automobile engines. Background technique [0002] As we all know, carbon deposits are a mixture of colloids in fuel oil that are condensed into asphaltene and oil coke after repeated heating. There are two main reasons for its formation: [0003] One is fuel volatilization or oxidation. Current engine fuels, such as gasoline and diesel, are mixtures of complex hydrocarbons. The main components of gasoline are C 4 ~ C 12 hydrocarbons (mainly C5 to C9), and the main components of diesel are C10 ~ C22 hydrocarbons (mainly C15 to C9). Mainly C18), during the storage and transportation of fuel oil, it is easy to oxidize with air to form colloidal substances, or the content of colloids in the fuel itself is very high (poor fuel quality), after these colloids and fuel oil are burned together, Carbon deposits will occu...

Problems solved by technology

[0004] Second, the fuel is not completely burned

[0005] From the above analysis, it can be seen that during the working process of the engine, carbon deposits will inevitably occur.

Carbon deposits will directly affect the power, economy and emissions of the engine, causing difficulty in starting, unstable idling speed, poor acceleration, rapid acceleration and tempering, excessive exhaust gas, increased fuel consumption and other abnormal phenomena, and even damage the engine, so remove carbon deposits is an urgent problem

[0006] Now there are usually two ways to clean carbon deposits: one is the physical method, disassemble each component of the engine one by one, clean and reassemble, this method requires superb technology and the original dust-free working environment, the implementation is difficult and costly high

The second is to use the chemical removal method, by adding chemical additives, but it is difficult to achieve the best mixing ratio between additives and fuel, which will affect the power of the vehicle, and it needs to be added every few thousand kilometers, and the operating cost is high

In addition, the biggest disadvantage of the above two solutions is that neither of them can completely eliminate the re-generation of carbon deposits. After the original carbon deposits are removed by using the existing methods, the fuel is volatile or oxidized to form colloids, and then repeatedly heated to condense into carbon deposits. , with the engine running, the unburned components in the injected fuel are deposited on the surface of the piston and the combustion chamber, which accelerates the formation of carbon deposits
