What's the difference between your car before and after cleaning up carbon deposits?

First of all, it is necessary to understand that carbon deposition is garbage produced after engine combustion, and cleaning up garbage is definitely beneficial. But according to the severity, the reaction effect after cleaning is different. If it is not too serious, you may not feel the effect after cleaning.

I'm glad to help you with your answer. We will answer from four aspects: how the carbon deposit is formed, the influence of excessive carbon deposit on the engine, the ways and means of cleaning the carbon deposit and the benefits after cleaning the carbon deposit.

Carbon deposit formed by colloid residue caused by insufficient combustion of combustible mixture during engine operation. There are many factors that affect the formation of carbon deposits, such as driving habits leading to engine overload and carbon deposits, mislabeling of engine oil and fuel, and driving conditions. These are the reasons for carbon deposition in the engine.

The formed carbon deposits are attached around the cylinder and spark plug, which affects the normal operation of the cylinder, reduces engine power, increases fuel consumption, and even produces abnormal noise when ensuring engine acceleration. Piston and crankshaft are damaged.

Obviously, we refer to the above 2 words, after cleaning up the carbon deposit, it will play a great role in the normal work of our engine, and it is the most intuitive and obvious to improve fuel economy and engine power. When my car has too much carbon, it feels boring to step on the accelerator. After cleaning up the carbon deposit, I feel that the throttle is light and the acceleration is more powerful. This is an intuitive performance.

The best way is physical cleaning. Remove the air inlet and brush it with a small brush, and the effect is obvious. It has little effect on removing carbon and softening bottles. If you run off the highway, the effect may be better. Of course, there are more advanced walnut sand cleaning equipment now, and the effect is also very good.

Ford Focus drove nearly 80,000 kilometers, and found that the fuel consumption was high, the power was weak, and the exhaust gas was not up to standard. After eliminating the hardware problem, a friend first made a "fuel-saving cleaning package", which was to clean the carbon deposit on the engine on site, and then installed a long-term "carbon removal and fuel-saving power riser". After 30 minutes, a lot of carbon deposits were washed out through the exhaust pipe. Coupled with fuel-saving assistance, the power is improved obviously after going on the road, saving fuel by about 20% (in the past, a box of oil could only run more than 550 kilometers, but now it can run more than 650 kilometers), and the idle speed is stable, and the engine sound is basically not heard. The effect is really good, and it is really obvious to exchange old cars for new ones.

First of all, it is necessary to find out where there will be carbon deposition and how it is produced.

Engine carbon deposit mainly exists in three places, namely, lubricating oil channel, intake channel and combustion chamber (cylinder).

Lubricating oil passage is the passage of engine lubricating oil (engine oil) and the gap between parts that need oil lubrication. The carbon deposit in these places is formed after the aging and deterioration of engine oil, which will seriously block the oil circuit, cause poor lubrication and damage the engine. In this regard, prevention should be given priority to, rather than waiting for carbon deposition to be cleaned up. If these carbon deposits are cleaned up, the cleaned carbon deposits may block the lubricating oil passage, resulting in serious consequences. Therefore, it is necessary to change the oil regularly at ordinary times, and it is not allowed to change the oil after deterioration, and it is also necessary to put an end to fake oil.

The intake passage refers to the intake passage from the air cleaner to the intake valve of the engine, with a throttle assembly in the middle, which is also commonly known as the throttle. The throttle assembly includes an idle speed control mechanism. The carbon deposition in these places is mainly caused by the combination of oil and gas brought by the introduction of engine ventilation pipe into the air inlet and dust in the air. Excessive carbon deposition in the air inlet will cause unstable idle speed or even no idle speed. Therefore, when the idle speed is unstable, it is necessary to clean up the carbon deposit at the air inlet, mainly the throttle assembly.

In general, there is little carbon deposit in the combustion chamber (cylinder), so it is unnecessary to clean it. The combustion chamber is in a high temperature and high pressure environment, and the carbonaceous material is burned into ashes and discharged from the exhaust pipe. The so-called idea of cleaning up the carbon deposit in the combustion chamber is all layman's words or deceptive for some purpose. The majority of riders should not be fooled. Speaking of this, some people may say that there is a lot of carbon deposition in the cylinder through the endoscope, and some even remove the cylinder head, which can obviously see a lot of carbon deposition in the cylinder. This is true, but it is caused by oil combustion, that is, the wear of piston ring and cylinder wall, so to solve the problem of carbon deposition in cylinder, we must first solve the problem of oil combustion. Otherwise, even if the carbon deposits are cleaned up, there will be carbon deposits soon. So if the engine doesn't burn oil, don't listen to any "good words" about cleaning the cylinder.

The intake valve and injector also have carbon deposits. The carbon deposit on the intake valve is closely related to the valve oil seal. If the valve oil seal is not good, too much oil will accumulate at the root of the valve guide rod, which will aggravate the generation of carbon deposit at high temperature. If the valve oil seal is normal, the carbon deposit on the intake valve actually doesn't matter, and it won't be serious. Some so-called professionals will say that carbon deposition in the intake valve will affect the intake volume, leading to a decline in power. The question is who drives a private car and will step on the accelerator to the end? Let the engine output at maximum power. Although the carbon deposit in the intake valve will increase the intake resistance, thus reducing the intake air volume, it seems to reduce the power. However, the throttle is at your own feet, so you can increase the throttle appropriately to make the throttle open properly, and the intake resistance can be made up. The engine computer controls the fuel injection quantity according to the air intake, so there is no problem of reducing power or increasing fuel consumption.

Strictly speaking, the carbon deposit on the fuel nozzle is not carbon deposit, but the glue in the fuel adheres to the fuel nozzle, which reduces or even blocks the fuel nozzle. This will lead to a reduction in fuel injection or even no fuel injection, and the driving experience is a power drop or even cylinder jitter. However, such failures are rare. With the improvement of fuel quality and the short mileage of most family cars, this kind of fault is not common, even if the nozzle is cleaned or replaced. If you want to prevent this kind of failure, you can add a fuel treasure to clean it up100000 km.

To sum up, in fact, carbon deposition is related to engine oil, such as carbon deposition in cylinders and intake valves. The first thing to be solved is the problem of burning engine oil, which can not be solved simply by cleaning up carbon deposits. If the engine does not burn engine oil, carbon deposition will not be very serious, and there will be no adverse effects, which can be completely ignored.

Carbon deposition in the oil gallery should be mainly prevented. As long as the oil is changed regularly and inferior oil is not used, there will be no carbon deposit.

Carbon deposition in intake air is inevitable, but it is not necessary to clean it frequently, and it is not too late to clean it when the idle speed is unstable. My car ran nearly100000 kilometers without doing any work to clean up the carbon deposit.

Now some so-called professionals with ulterior motives often say that carbon is discolored. In fact, carbon deposition is not so terrible. Under normal engine conditions, there is absolutely no need to clean this and that. Is there any other way to improve the speed of removing carbon deposits? It's a fallacy and heresy. It's totally unnecessary.

I'm glad to answer your question. Actually, it's a matter of personal feeling. Some people will feel that the sound throttle of the same car is much lighter after cleaning, while others will feel that it has not changed. Just like those of us who don't know music, dozens of headphones and thousands of headphones sound the same, haha. But the cleaning of carbon deposits should be done, just like we have something dirty in our throat, so we should take some medicine or drink water. Cleaning up the carbon deposit will really be good for the engine. The sound is lower, the throttle response is faster, the idle speed is stable, and the acceleration is easier. Therefore, whether you feel it or not, and whether others feel it or not, cleaning up carbon deposits is an essential link for your car.

Assuming it can be cleaned up! After cleaning, the compression ratio returns to the original value. When the car is cold, the engine jitter disappears and is relatively reduced or changed.
