What about the engine power shortage of FAW-Volkswagen Bora?

After the car engine produces carbon deposit, there will be problems such as insufficient power, slow acceleration and high fuel consumption. People usually set the shift mode of the vehicle to manual at high speed, and speed up from low gear to high gear to more than 3000 rpm in turn, and each gear lasts for at least 5 minutes, which can effectively remove the carbon deposit from the engine! But what about those die-hards who deposit carbon?

Let's talk about why car engines produce carbon deposits after a long time.

Mainly because of incomplete combustion of gasoline or nonflammable paraffin colloid, residues are formed in spark plugs, oil pipes, nozzles and other parts. Under the action of high temperature, carbon deposits are formed over time.

The first cleaning method is "hanging bottle". In this way, if the engine with light carbon deposition is serious, it is easy to cause blockage and damage of the three-way catalytic system. In fact, the bottle is filled with cleaning agents that have been pressurized and atomized. These cleaning agents are put into the valve, nozzle, air inlet and other parts, and the carbon deposits are dissolved through chemical reaction, and the carbon deposits are discharged by the high-speed operation of the engine.

The second cleaning method is relatively simple. Just clean the valve and air inlet, just spray the valve and air inlet with cleaning agent, or even clean it directly without disassembling the valve. This method has certain effect, but it is not thorough. It's best to make a hanging bottle. Sometimes the garage will make it for you conveniently.

Third, the cleaning agent is sprayed into the combustion chamber through high pressure, and then the liquid is pumped out through the chemical reaction between the cleaning agent and the carbon deposit. This method also has disadvantages. If the carbon deposit is serious, the large carbon deposit will also damage the combustion chamber if it cannot be pumped out.

The last one is disassembly and washing, which is to thoroughly clean the engine with serious carbon deposition. The cleaning effect is ideal, but it is more troublesome and expensive. This method will not be used until the end.

Engine carbon deposition is inevitable and can only be cleaned up frequently and simply. Avoid driving at low speed for a long time and hot cars in the same place during daily driving. These conditions will accelerate the formation of carbon deposits. Also, when refueling, be sure to add cleaner fuel.
