• Reasons for high carbon accumulation in automobiles

Why does the car engine generate carbon accumulation?

1. The main reasons are as follows. The condition of the spark plug is not good. For example, the "spark" is too weak, and the mixed steam is not easy to burn, producing "carbon accumulation". 2) Ignition is not "timing". The action of each "cylinder" of the engine completes 4 strokes according to the "law" cycle.

2. The main reason for the formation of carbon accumulation is insufficient combustion, which is related to driving habits, road conditions and fuel quality. Carbon accumulation will be formed on the valve, combustion chamber, piston, fuel injector and spark plug parts.

3. Carbon accumulation is mainly caused by incomplete combustion of fuel in the engine, or incomplete combustion of paraffin colloids in gasoline, remaining in fuel nozzles, throttle valves, oil pipes, spark plugs and other parts, and converted into carbon accumulation under the action of high temperature.

What is carbon accumulation and how to deal with carbon accumulation in automobiles

Carbon accumulation is the rubber carbon accumulated on engine components such as engine valves, intake branches and fuel injectors. When the engine is working, some components in gasoline will condense into glue carbon, and the condensed glue carbon will continue to accumulate, thus affecting the normal operation of the precision engine management system. The way to slow down the formation of carbon accumulation: use high-quality fuel oil.

Carbon accumulation is in engine oil and fuel during engine operation.The residue produced by incomplete combustion of unsaturated olefins and colloids at high temperatures, with the timely discharge of the exhaust gas, these residues do not accumulate in various positions of the system, thus forming a black coke substance called "carbon accumulation".

Use high-quality fuel. Because the main components of carbon accumulation are wax and colloidal deposition in the fuel, the lower the colloidal content in the fuel, the better. But we can't change the quality of fuel, but we can choose not to add cheap fuel of unknown origin. Avoid driving at low speed for a long time. If necessary, you can pull the highway regularly.

These things can't be burned cleanly. After burning, there are residues, and these residues accumulate to form carbon. There are generally two reasons for the formation of carbon accumulation. The first is that there is a problem with the oil. The "three giants of domestic automobiles" - PetroChina, CNOOC and Sinopec - cannot avoid adding some olefins and other substances.

Pulling the high speed, theoretically achieves the cleaning effect of the carbon accumulation on the surface through high speed and combustion, but it cannot achieve fundamental cleaning; boom the accelerator, you try to see how much oil you can burn.

The performance of automobile carbon accumulation

1. The performance of automobile carbon accumulation is as follows: the power of the automobile has weakened. When the car has difficulty in starting or going uphill, or has symptoms of refueling, it means that the carbon is blocked. It is difficult to start a car. A large part of the reason why cars can't start continuously is car carbon accumulation. Abnormally turned off.

2. The engine is not working well, and there are abnormal phenomena such as difficulty in starting, unstable idle speed, poor acceleration, urgent refueling and refueling, exhaust gas exceeding the standard, and increased fuel consumption.

3. The engine is unstable, and the speed is high and low.The driving feeling is dull, especially when overtaking, and the acceleration response is slow, which is very different from the new car. The exhaust of the car came to the nose, and the emissions exceeded the standard. The fuel consumption of cars has increased a lot compared with before. There is a way to judge the accumulation of carbon on cars.

4. When the carbon accumulates attached to the intake and exhaust valve, the inlet and exhaust valve is not closed tightly to the point of air leakage, and the pressure in the engine cylinder drops. The direct result is that the engine is difficult to activate and jitter under idling conditions; at the same time, it affects the cross-section of the mixed gas entering the combustion chamber, and the carbon can adsorb a certain amount of mixed gas. So as to reduce the engine power.

How to deal with automobile carbon accumulation

1. Car carbon accumulation treatment method At present, there are only two ways to remove carbon accumulation in the repair factory. One is to use the disassembly-free cleaning method that the carbon accumulation is not serious, and by adding a special cleaning liquid to clean it. Wash.Second, if the carbon accumulation is serious, the method of removing the cylinder head to clean the valve and cylinder block should be adopted.

2. The method of carbon treatment is as follows: the car hangs the bottle. Hang a bottle-shaped tool above the engine, then pour the detergent into the bottled tool and introduce it into the engine through the condit to achieve the purpose of cleaning the carbon. The price is about 1,000 yuan.

3. How to clean up the carbon accumulation of the car engine? The treatment methods are as follows: Add high-standard gasoline to rinse, because the high-label gasoline added is relatively high-standard gasoline with a relatively high octane, and the combustion is complete and clean, and the possibility of forming carbon accumulation is relatively much lower. Through high-standard gasoline can Effectively rinse the residual carbon.

How to prevent and reduce the formation of carbon accumulation in cars

The purpose of running more at high speed is to use the washing effect of airflow on the intake duct to prevent carbon accumulation.

Be sure to fill up high-quality gasoline. Impurity such as wax and glue in gasoline is the culprit of carbon accumulation, so the tendency of high-clean gasoline to form carbon accumulation is weaker.

Run more at high speed and try to increase the gearshift speed of the manual transmission car. The purpose of running more at high speed is to use the washing effect of the airflow on the intake channel to prevent carbon accumulation.

Love the car at ordinary times and maintain good driving habits, which can indeed play a preventive role. Six ways to prevent carbon accumulation for riders' reference. Clean the empty air filter frequently. Do not often drive on dusty roads, and often clean the empty air grille (empty air filter), which can also reduce carbon accumulation.

Avoid idling for a long time and turning on the air conditioner at idling. When idling, the engine has less air intake and cannot effectively blow out the carbon in the engine. Moreover, idling is not conducive to engine heating. When the engine temperature is low, gasoline evaporates slowly, which will accelerate the formation of carbon accumulation.

The way to reduce carbon formation: use high-quality fuel. Because the main components of carbon accumulation are wax and colloidal deposition in the fuel, the lower the colloidal content in the fuel, the better.But we can't change the quality of fuel, but we can choose not to add cheap fuel of unknown origin. Avoid driving at low speed for a long time.

Reasons for high carbon accumulation in automobiles

1. The failure of the car itself leads to excessive fuel injection and incomplete carbon accumulation generated by combustion. These are the reasons for the formation of carbon in automobiles. However, within 100,000 kilometers, it will not affect the car.

2. What is the cause of carbon accumulation? Bad driving habits caused by drivers' long-term bad driving habits. Many drivers are reluctant to step on the accelerator when driving in order to save fuel and cherish the car. In this way, driving will not only not save fuel but also increase engine carbon accumulation.

3. Why does the engine have carbon accumulation? Is there any way to prevent and clean it up?Content overview: the causes of carbon accumulation, the wrong way to clean up carbon accumulation. [Engine carbon accumulation] is an eternal topic of fuel-powered cars. The reason is that carbon accumulation will be generated as long as the car is used normally, and most users do not know the correct driving method to prevent carbon accumulation.

4. Road conditions lead to: We will find a principle that in cities and countrysides with smooth traffic, vehicles rarely have serious carbon accumulation, which leads to insufficient combustion and carbon accumulation due to insufficient combustion on the road.

5. Reasons for the different severity of carbon accumulation in vehicles: the quality of fuel. The oil with high standards has high purity and is easier to fully burn, but the price is expensive, and the fuel at small gas stations is different. The same label has a much different price, so many car owners choose to go to small gas stations to refuel, thinking that the label The same fuel is the same.

6. The carbon accumulation in the top of the piston and the cylinder head is easy to cause the combustion chamber to overheat and the gasoline preheat, causing engine explosion and other faults. These failures will shorten the service life of the engine.
