What kind of harm does car carbon deposition cause to vehicles?

Hazards of carbon deposits:

One is to reduce the engine power, causing the car to become more and more weak.

The second is to increase fuel consumption and increase the economic burden.

Third, it is difficult to start cold, and it is not easy to get on the car.

Fourth, serious carbon deposition in the combustion chamber will also cause cylinder detonation, causing damage to the piston and crankshaft.

Fifth, the emission exceeds the standard, which is difficult to pass the annual inspection, which directly aggravates environmental pollution.

How carbon deposits are formed.

Why is carbon deposited generated? This is because the fuel itself contains gum, impurities, dust, moisture, etc., which accumulate over time to form sludge and other deposits in the fuel tank, oil inlet pipe, etc.; Secondly, due to the oxidation and polymerization reaction of unstable components such as olefins in gasoline at high temperatures, colloidal and resinous viscous substances are formed, which stay in the fuel injector, air intake valve and other parts, and the deposits will become hard carbon deposits when burned.

In addition, traffic congestion, cars are often at low speed and idling, which can aggravate the formation and exacerbation of carbon deposits and sediments. If the carbon deposit is not cleaned in time, the carbon deposit and sediment will block the injector needle valve and valve hole, resulting in the intake valve not being closed tightly, the cylinder pressure dropping or even tempering, resulting in unstable engine idling, increased fuel consumption and deterioration of exhaust emissions. Carbon deposits on the piston top and cylinder head can easily cause local overheating of the combustion chamber and gasoline preheating, resulting in engine knocking and other failures.

These failures can shorten the life of the engine.

How to judge the organic carbon of a car? When the car has the following conditions, it can be judged that the carbon deposition of the car is more serious:

1. It is not easy to start when the cold car is ignited many times, and it is normal when the car is hot;

2. The engine idle speed is unstable, and the speed is high and low;

3. The driving feeling is weak and stuffy, especially when overtaking, and the speed response is slow, which is very different from the new car;

4. The exhaust of the car is pungent and the emission exceeds the standard;

5. The fuel consumption of the car has increased a lot compared with before.

How to clean up the best way to clean up carbon deposits in automobiles.

Generally, the commonly used methods are: dismantling and washing, hanging bottle cleaning, and fuel additives.

1. Dismantle and wash. This method is very direct and rude, but it is generally sent to the 4S store for disassembly, the disassembly of the engine is more complicated, no matter what parts will affect its performance more or less every time it is disassembled, you need to ask a professional master to disassemble. The carbon deposits in the engine can be seen directly when dismantled and washed, and the cleaning will be relatively clean.

However, the cost will be relatively high, and it will also require technology.

2. Hanging bottle cleaning.

This method is also relatively common, the hanging bottle is to discharge the cleaning agent into the air intake, dilute and soften the carbon deposit to turn it into a slurry, and then burn it from the cylinder to discharge. Generally, the cleaning objects include the intake tract, throttle, intake valve, fuel injector, cylinder inside, etc., but the effect is not as direct and obvious as dismantling and washing.

3. Fuel additives.

The main function of additives is to drill into the pores of carbon deposits with the help of strong surface activity, destroy their structure, and gradually dissolve these carbon particles from the metal surface, and then discharge them through exhaust gas after burning with fuel at high temperatures. Effective fuel additives such as PNF stock solution are non-corrosive, will not clog ternary, and have a relatively high level of safety.

will make the engine power decrease. Increased fuel consumption. He will emit black smoke.

Carbon deposition can be divided into two types: valve, combustion chamber carbon deposition and intake pipe carbon deposition.

1. Carbon deposition in the valve and combustion chamber.

Determined by the control characteristics of the electric injection engine, the cylinder is first injected and then ignited every time it works, when we extinguish the engine at the moment of ignition is cut off immediately, but the gasoline sprayed out by this work cycle can not be **, can only be attached to the intake valve and combustion chamber wall, gasoline is easy to volatilize, but the wax and gum in the gasoline are left, and the wax and gum in the gasoline accumulate more and more thickly, and the carbon deposit is formed after repeated heating and hardening. If the engine burns oil, or if the gasoline is of inferior quality and has more impurities, then the valve carbon deposits are more severe and form faster. Because the structure of carbon deposition is similar to that of a sponge, when the valve forms carbon deposition, a part of the fuel injected into the cylinder will be adsorbed, which makes the concentration of the mixture that really enters the cylinder thinner, resulting in poor engine work, and abnormal phenomena such as difficult starting, unstable idling, poor acceleration, urgent refueling and tempering, excessive exhaust gas, and increased fuel consumption.

If it is serious, it will cause the valve to be closed loosely, so that a cylinder will not work completely due to no cylinder pressure, and even adhere to the valve to prevent it from returning. At this point, the valve and piston will interfere with the movement, which will eventually damage the engine.

Second, carbon deposition in the intake pipe.

Because the work of each piston of the whole engine is not synchronized, when the engine is extinguished, the intake valves of some cylinders cannot be completely closed, and some unburned fuel continues to evaporate and oxidize, which will produce some soft black carbon deposits in the intake pipe, especially behind the throttle. On the one hand, these carbon deposits will make the wall of the intake pipe rough, and the intake air will produce vortices in these rough places, affecting the intake effect and the quality of the mixture. On the other hand, these carbon deposits will also block the idle channel and make the idle control device stuck or out of its adjustment range, which will cause low idle speed, idle shivering, the speed of various auxiliary devices are out of order, oil collection and vehicle extinguishing, exhaust gas exceeding the standard, fuel consumption and other phenomena.

[Hazards of carbon deposition] - the increase of carbon deposition in the fuel system is easy to reduce the engine performance, and in serious cases, it will lead to engine failure, shorten the engine life, and it is very important to regularly clean and maintain the fuel system.

1.It causes a series of failures such as engine trembling, driving weakness, poor acceleration, cold start difficulties, increased gasoline fuel consumption, and increased oil consumption;

2.Shorten the service life of three-way catalytic converters, oxygen sensors, spark plugs and other parts;

3.In serious cases, it will cause valve ablation, sticky valves, premature ignition, deflagration, cylinder knocking, cylinder pulling, and damage to the engine block, which needs to be overhauled or even scrapped;

4.Waste your valuable time and repair costs.

Let's talk about buying a car, using a car, maintaining a car, and repairing a car.

There are a lot of hazards, such as increased fuel consumption, idle jitter, and poor performance, it is best to use a good cleaning agent for regular maintenance, I generally use Billiton's LA112, and the cost performance is OK.

Shenzhen's Mosheng Technology, its products are more than other auto repair centers have a repair function, it can repair worn metal parts, and has super protection ability, improve the power of the car, reduce fuel consumption, reduce noise, improve exhaust emissions, and extend the service life. It is recommended to use Mosheng.

Serious carbon deposition in the engine cylinder will cause cylinder wear!

It should be caused by low speed and high gear, caused by insufficient combustion, manual transmission car gear retreat should be in accordance with the tachometer, high speed 3000-3500 conversion gear is better, speed 50km h directly hang five gears strongly do not despise, the final result is increased fuel consumption. The 5th gear of the high-speed car should be around 4000 rpm, and the speed of 140km h is acceptable, but the 2nd gear is 3500 rpm, but you can't accept it. If you think about it yourself, it's not difficult to understand.

It mainly has an impact on power and fuel consumption, and if the carbon deposit is more serious, it will also aggravate the wear of the parts.

The hazards of carbon deposits to the engine can be divided into two aspects: structural damage and performance degradation

1) Structural damage:

The various structures in the cylinder that make up the combustion chamber are the main parts where carbon deposition occurs, including the top of the piston, the spark plug, the injector in the cylinder, the intake and exhaust valves, and the cylinder inlet of the intake pipe.

2) Leads to a decrease in engine performance.

The main reasons for the power decline --- serious carbon deposition are: spark plug carbon deposition weakens the ignition ability or causes ignition failure, and the pressure drop caused by cylinder leakage (valve and piston), etc., which is more obvious at high load or low speed.

An increase in fuel consumption --- a decrease in power is accompanied by a certain increase in fuel consumption, as greater throttle opening and increased fuel supply are required to obtain the same power as before the effects of carbon deposits. Therefore, if there is an unexplained increase in fuel consumption, it is necessary to check for the presence of carbon deposits in the cylinder.

Emissions of pollutants from the exhaust gas increase--- and it is usually not noticed until the annual inspection of the car that the pollutant emissions in the exhaust gas are increased. At present, only carbon monoxide, hydrocarbons and nitrogen oxides are detected, and all three indicators can rise or exceed the standard when carbon is deposited, which may occur earlier than the decrease in power and the increase in fuel consumption.

Other changes--- there may also be difficulties in cold start, abnormal noise during acceleration, etc.; When the piston carbon deposit is severe, it may cause the piston ring to be stuck and scratch the cylinder wall, resulting in serious air leakage (cylinder pulling).

Ways to reduce, prevent, and remove carbon deposits:

First: refill with high-quality gasoline.

Impurities such as wax and gum in gasoline are the main components of carbon deposits, so gasoline with high cleanliness has a weaker tendency to form carbon deposits. Unfortunately, at present, the quality of gasoline in China is still low compared with developed countries, and it can only be simplified because of ugliness. It should be noted that high grade does not equal high quality, that is to say, the oil of No. 97 is not necessarily less impurities than that of No. 93, and the label only represents the octane number of the oil, not the quality and cleanliness.

In order to ensure the cleanliness of gasoline, some car owners will adopt the practice of adding gasoline detergent to gasoline. This can effectively prevent the formation of carbon deposits on the metal surface, and can gradually activate the original carbon deposits and slowly remove them, so as to protect the engine from damage. However, the addition of gasoline detergent must be cautious, if you add shoddy products, you will get the opposite effect.

Second: Don't idle for long periods of time.

The longer the idle time, the longer the engine reaches normal temperature, and the slower the rate of evaporation of gasoline when it is injected into the back of the valve, which creates carbon deposits. At the same time, if you are driving at idle speed, the air flow into the engine will be small, so the scouring effect on carbon deposits will also be weak, which will promote the deposition of carbon deposits.

Third: run more high-speed and try to increase the shift speed of the hand-stop car.

The purpose of running more high-speed is to use the scouring effect of the air flow on the intake tract to prevent carbon deposits. In addition, increasing the speed of shifting gears is also similar to running at high speed, turning the original gear shift at 2000 into 2500 conversion, which can not only effectively prevent the generation of carbon deposits, but also improve the dynamics of the car, and also avoid the detonation caused by too low shift speed and protect the engine.

Fourth: the use of car Bell carbon invincible.

**Search directly for Che Bell Carbon Invincible, on the line, or go to the Che Bell official website to buy! However, this can only remove carbon deposits from the fuel system, valves, fuel injectors, ternaries, and combustion chambers, and other parts of the car need to be cleaned separately.

Fifth: dismantle the machine for cleaning.

I won't go into detail about this, you know.

Gasoline carbon deposits are mainly caused by inadequate combustion of the engine. In this state, a viscous substance is produced that accumulates in various parts of the engine and has an oil-absorbing effect. In the long run, the incomplete combustion of gasoline will turn into carbon deposits again, leading to a vicious cycle of frequent engine failures.

1.Carbon deposits can get stuck in the exhaust valve, resulting in a series of failures such as poor closure of the exhaust valve, insufficient pressure in the engine cylinder, difficulty in starting the engine, and reduced engine power.

2.When carbon deposits form in the intake pipe, it can lead to roughness in the pipe, which can affect the formation and concentration of the combustible gas mixture.

3.Carbon deposits on the piston can cause the piston to seize, which can lead to oil combustion and cylinder wall strain.

4.When carbon deposits adhere to the spark plug, the mass of the spark decreases and even ignites suddenly.

How do I clean up carbon deposits?

1. The car hits the bottle.

Hang a bottle tool on the engine so that it can be filled with detergent, which can then travel along the tube to the inside of the engine, thus cleaning the carbon deposits. (Note that this method is only suitable for mild carbon deposition, and in severe cases, it will cause damage to the three-way catalytic system).

2.Machine cleaning.

The cleaning agent is poured into the machine, and the cleaning agent inside is allowed to contact the combustion chamber through the pressure of the machine, so that the cleaning agent reacts with the carbon deposit. After the cleaning agent dissolves the carbon deposit, the waste oil is pumped out to achieve the cleaning effect. This method has a better cleaning effect for cars with serious carbon deposits, and does not need to be disassembled and cleaned, which has development momentum.

What are the dangers of carbon deposits in automobiles.

If the carbon deposit in the engine cylinder is severe, it will cause spark plug blockage and valve blockage, which will directly cause the car to shake when idling. In this case, clean the fuel injector, throttle, oil circuit and intake pipe one by one, or replace it with Kunlun Tianrun KR9-T fully synthetic engine oil.

There are many hazards caused by carbon deposits, such as fuel consumption, engine power attenuation, and wear and tear of parts, which affects the safety of automobiles. The most obvious manifestations are weak acceleration, increased fuel consumption, and engine shaking. In severe cases, the vehicle may also have difficulty starting.
