The essence that distinguishes humans from other living beings is the ability to freely control one of nature's greatest powers, fire.
With fire, human civilization can be said to have progressed rapidly, and gradually, human control of fire has shifted from using fire externally to using fire internally, such as the internal combustion engine.
The invention of the internal combustion engine has led to the rapid development of automobiles, which bring us convenience and speed, but at the same time consume a large amount of non-renewable precious energy.
However, a car engine that uses combustion as a way to do its work, like the fuel it uses, will gradually go from its peak state to weaken, and in the process,The biggest injury to the engine is not its own wear and tear, but carbon deposits.
In other words, it is the decline in motivation caused by carbon deposits.
Carbon deposition is a phenomenon in which residues from the combustion process of an engine accumulate inside the engine or in the exhaust system。These residues can be deposits in solid, liquid, or gaseous form.
Let's take an example of carbon depositsImagine the engine of a car, when burning gasoline or diesel, the fuel mixes with air and ignites, creating the ability to propel the piston motion and thus drive the vehicle forward.
However, during combustion, some fuels cannot be burned fully due to incomplete combustion and are left in the form of particulate matter. These residues are emitted into the atmosphere through the exhaust exhaust system, and some of them are deposited on various components inside the engine.
These carbon deposits may include:Carbon black, oxides, oil stainsWait.
They are deposited on engine components such as cylinder walls, piston rings, valves, and intake tracts, forming a layerBlack or brown depositsCarbon deposits can gradually increase over time and can adversely affect engine performance.
1. Engine combustion chamber
Engine combustion chamber. The carbon deposits in the combustion chamber are mainly distributed on the top of the piston, the spark plug, and the wall of the combustion chamber. Since the combustion is a direct occurrence, there will be a little more carbon deposit.
This is similar to the earthen stove burned in our countryside, where there is a little more black soot in the stove cavity.
Moreover, the causes of carbon deposits in the combustion chamber are relatively complex.
For example, gasoline itself has something called "aromatics", which is present as long as it participates in combustion.
And then the oil is also possible. It is also possible that when steam escapes in, and when the combustion conditions are not good enough, it may lead to the generation of carbon deposits.
2. Air intake system
Carbon deposits may occur in the intake system, such as throttle valves and intake manifolds.
As mentioned above, a part of the oil mist in the engine will enter the throttle valve, and after being volatilized by high temperature, its wax and gum will be retained, which will adhere to the soot from the combustion chamber, thus forming carbon deposits.
The throttle is to control the size of the air intake, and too much carbon deposition may affect the opening of the throttle, resulting in insufficient air intake.
What is this kind of like?It's like: we have a cold, and we have a blocked nose, so we don't breathe very well, and we don't run very fast, which means the same.
3. Carbon deposits in the cylinder
Carbon deposition in the cylinder refers to the carbon deposition at the top of the piston, which is produced by the gasoline problem, and the gum in the gasoline cannot be burned, and is gradually deposited at the top of the piston, and hardened by high-temperature cauterizationThe presence of carbon deposits here will reduce the combustion chamber area, resulting in a decrease in power, and will cause deflagration and detonation, which will have a greater impact on the engine.
1. If there is more carbon deposition, the increase in fuel consumption will be more obvious
The essence of carbon deposition is that the impurities produced are not removed in time due to insufficient combustion of gasoline, and they will be attachedEngine, fuel injector, three-way catalytic converterand other places.
When there is too much carbon deposit, the oil is even more unable to burn sufficiently, so you need to press the throttle more often, so that the amount of fuel injected will increase. In contrast, fuel consumption will increase, and carbon deposits will also accumulate, and there will be a vicious circle between carbon deposits and fuel consumption.
Therefore, when the fuel consumption becomes abnormal, it must be checked and eliminated in time to see if there is too much carbon deposit.
2. There is black powder in the engine
Car owners can check if there is a condition inside the engineBlack carbonized powderIf there is, it is an abnormal phenomenon, which means that it needs to be cleaned up in time to avoid greater engine failure.
3. The smell of car exhaust is very strong
If you smell the gas coming out of your car's exhaust pipe outside the car smelling very strong and pungent, it may also be a problem with carbon deposits, because:Carbon deposits in the engine may be attached to the three-way catalytic converter along the exhaust duct, an unpleasant odor appears.
At this time, it will also affect the work of the three-way catalytic converter, that is, the phenomenon of emission not meeting the standard, so during the annual inspection of the car, the car emission is not up to standard, which is likely to be caused by carbon deposition.
The sales of turbo cars in the market are increasing year by year, and many people are choosing to buy this model.
This is mainly because turbocharging technology can improve the performance of automobiles in many aspects, such as power, fuel economy and environmental protection, and has been widely recognized by consumers.
However, even with the advancement of times and technology, it is true that turbo cars are still more prone to carbon deposits and are a little more delicate than naturally aspirated cars for two reasons:
1. Turbine vehicles are prone to dehydrogenation
First, the engine intake of a turbo vehicle is pressurized, and the temperature is higher, which is prone to dehydrogenation after combustion with gasoline.
In layman's terms, the hydrogen and oxygen in gasoline are burned first, and after burning, the oxygen is insufficient, so the carbon-containing impurities are easy to stay, forming carbon deposits.
2. The fuel supply method of turbine vehicles is more likely to lead to carbon deposits
The second reason is that the way turbine vehicles are supplied with fuel is more likely to lead to carbon deposits.
The fuel supply method of naturally aspirated cars is basically manifold injection, but turbo vehicles mainly use in-cylinder direct injection technology.
To put it mildly, the fuel injector is moved from the outside of the cylinder to the inside of the cylinder, so that the gasoline is injected directly into the combustion chamber. This has the advantage of saving fuel and improving combustion efficiency.
Advantages and disadvantages generally coexist, and most things do.
The injector head is exposed to high temperature and high pressure combustion gas, which will increase the formation tendency of carbon deposition in the injector, and not only the fuel injector, but also the intake valve, exhaust valve, combustion chamber and other parts will also cause carbon deposition to occur more easily than the naturally aspirated engine because of the direct injection technology in the cylinder.
1.Long-term idling - an eternal pain in the heart of every driver in the city
Driving on the road, half an hour's journey can be driven for two hours, whether it is an elevated or ordinary road, traffic jams are desolate. If you find that you can't move in a short time, let's take the initiative to turn off the ignition and wait.
Friendly reminder: If your car has an automatic start-stop function, it can not only effectively prevent carbon deposits from the engine from long-term idling, but also effectively reduce fuel consumption.
2.Frequent short drives – the norm for people with metro bus phobia
In order to avoid the crowded buses and subways, some car owners and friends also drive two or three kilometers away. However, often driving short distances, the engine is unable to reach optimal operating temperatures, resulting in insufficient fuel combustion and carbon deposits. Therefore, it is recommended that you travel low-carbon, ride a shared bicycle for two or three kilometers, and exercise by the way.
3.Gasoline is of poor quality - greedy for small and cheap suffers big losses
Poor quality gasoline has a lot of impurities and cannot be fully combusted, resulting in carbon deposits inside the engine. Therefore, please be sure to choose a regular gas station to add high-quality gasoline to your car, and don't be greedy for a small bargain.
When we notice the following conditions in our car while driving, we should pay attention, which means that the carbon deposition of the vehicle has been very serious.
1.It will reduce the power of the engine, which will lead to uneven and gradual attenuation of power output, and to put it bluntly, you will feel that you are powerless to drive.
2.Fuel consumption increases, increasing the economic burden.
3.It is difficult to start cold, that is, it does not catch fire, especially in winter.
4.Excessive carbon deposition in the combustion chamber will also cause cylinder knocking, and there will be noise when accelerating at low speeds, which will damage the piston and crankshaft, and seriously affect the safety of the car.
5.If the discharge exceeds the standard, it will not only fail to pass the annual review, but also directly increase the harm of environmental pollution.
Because the structure of carbon deposition is similar to that of a sponge, all the fuel cooked into the cylinder will be adsorbed every time there is carbon deposition in the valve, resulting in a smaller concentration of the mixture that actually enters the cylinder, resulting in poor engine work, difficult starting, unstable idling, poor acceleration, urgent refueling and tempering, excessive exhaust emissions, and increased fuel consumption.
In more severe cases, it can also lead to poor valve closure, resulting in no cylinder pressure in the cylinder and then a strike, and it will also cause the valve to stick and not respond. At this point, the valves and pistons are interfered with movement, which eventually damages the engine.
So for the safety of our cars, we must do a good job of cleaning up carbon deposits!
For this answer,It can't be said that it can't be cleaned at all, but the effect is very limited.
Pulling the speed is to increase the speed, so that the intake and exhaust pressure increases, and some of the carbon deposits attached to the engine will be washed away, but this is only for those who do not form a solid state, once a solid state is formed, then this method will not work.
The so-called pulling speed mainly refers to pulling the engine speed up, not how fast the car drives. Let the engine continue to operate at high speed, maintain a relatively high intake and exhaust pressure, the speed is high, the inhalation should be more inhaled, and the exhaust should be discharged more. In this way, the carbon deposits that are not completely attached to the surface of the cylinder can be washed away.
On the other hand, due to the high load operation, the electrode of the spark plug can basically produce a high temperature of about 500 degrees, and the area of carbon on the spark plug can be burned directly. It was scorched before, and if it was burned to ashes at a higher temperature, it would blow out.
Therefore, pulling the high speed can indeed remove some of the carbon deposits, especially the kind of carbon deposits that are not completely solidified, or can really be removed like oil sludge. But if it is the kind that has been burnt and clings to the wall, it must be cleaned in an effective way.
