Why does the car tremble more after cleaning the carbon deposits?

Hello, it was washed the throttle. Is it so?

The car ran 100,000 kilometers and needed to be cleaned upCarbon depositsOtherwise, it is easy to affect the service life of the car. The reason why the idle shake can't be checked may be because you check it incorrectly, and it's best to check the engine.

Nowadays, automobiles have become an essential means of transportation for a large number of people in their daily lives.

But if you can't take good care of yourself, it is easy to cause problems with the car. When driving a car for a certain distance, it is necessary to carry out a maintenance work, otherwise it is easy to cause traffic accidents.

Cars clean up carbon deposits.

Under normal circumstances, we recommend that the carbon deposits need to be cleaned up after driving the car for 50,000 kilometers normally, otherwise it is easy to damage the engine and affect the normal service life of the car. Generally, we can send the car to the 4S shop for inspection and maintenance, in addition, we can also buy a carbon deposit bag online to clean up by ourselves, although it is not possible to clean it completely, but to a certain extent, it can also maintain our spike car engine.

Causes of idle jitter.

When the car idles and shakes, a large part of the reason is that there is too much carbon inside the engine, and the carbon deposit can be cleaned up at this time. In addition, it may also be because of the ignition system of the car and the unstable oil pressure of the fuel system, especially when the cylinder pressure of the engine is insufficient, it is particularly easy to cause problems when the car is working, and there may be shaking when the car is idling, so it must be checked and repaired in time.

What should I do if I can't check the cause of the idle jitter?

If the car idles and shakes but cannot check the cause, it must be sent to a regular 4S shop for inspection and maintenance. Usually, guess that the engine will be disassembled under the orange bureau, check whether there is a problem with the parts, and do not check and repair yourself, it is easy to cause traffic accidents because of your own negligence. Remind all riders to carry out regular maintenance after driving the vehicle for a certain mileage.

Effects of excessive carbon deposition in the combustion chamber:

1. The engine combustion chamber is the worst place in the working environment of the car, which is under high temperature and high pressure for a long time. Inevitably, carbon deposits also occur here, mainly from the pyrolysis of incompletely burned fuel. The carbon particles here are hard and pot-shaped, and in severe cases, they are honeycomb and have a certain thickness;

2. The carbon deposition here will affect the intake vortex, hinder the rate of flame propagation, and lead to a decrease in power, which will lead to engine knocking (commonly known as cylinder knocking), and even excessive pressure leading to combustion chamber breakdown;

3. Slight carbon deposition does not matter much, but carbon deposition in the combustion chamber is an accumulation process from slow to fast, so daily cleaning is very important.

4. It is difficult to start the vehicle in winter, and the engine shakes after starting, and even causes the engine not to start; There will be a lack of acceleration of the vehicle; Idle shaking of hot cars; The phenomenon of blind increase in the oil consumption segment; Every carbon deposit inside the engine will have a bad impact on the normal operation of the engine, and in severe cases, it will cause irreversible damage to the engine piston.

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 with poor combustion width can be seen directly when dismantled and cleaned, 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, soften the carbon deposition and 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.

One of the causes of carbon deposition is that the fuel burns insufficiently, which adheres to various parts of the engine and forms carbon deposits over time. 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 not corrosive, can clean the whole oil circuit, fuel tank impurities, fuel tank moisture, high-pressure oil pump, built-in gasoline filter, fuel injector, piston top, intake valve, exhaust valve, will not clog ternary, and the safety is relatively high.

Of course, you need to clean up the carbon deposits, because after driving 100,000 kilometers, there may be a lot of carbon deposits in the engine. It is normal for the idle shake to not be able to find out the original cover because of the cherry skin, because the carbon deposits in the engine will not make the car shake. Spinal stuffiness.

Of course, the carbon deposits should be cleaned up, in fact, the carbon deposits should be cleaned up after about 10,000 kilometers. It is normal that the cause of the idle jitter of the pin combustion cannot be detected, because the carbon deposit will not cause the engine to imitate abnormal noise.

Of course, the carbon deposits should be cleaned up, because the carbon deposits of 100,000 kilometers are still more rotten than others, which will affect the life of the engine. Carbon deposits will not affect the shake of the engine, so the idle speed cannot be detected.

Cars have carbon deposits.

, fuel consumption will increase, power will decrease, so carbon deposits should be cleaned regularly. Many car owners reported that fuel consumption not only did not decrease after the carbon cleansing, but increased or jittered more severely. Isn't it washed well?

Still not cleaned? After washing the carbon deposits, the shaking of the car is even worse, what is going on?

Originally, there was a lot of carbon accumulation, and it is normal for fuel consumption to increase in the short term after the cleaning is over. Because the car computer has the function of automatic adjustment and automatic adaptation. Suppose there is a lot of carbon deposits in the original nozzle, and the milk powder worker is partially blocked by the carbon deposits, the amount of milk powder will be reduced at the same time, and the engine computer will adjust the milk powder time, so that the vehicle can continue to run smoothly, prolong the milk powder time, the flow rate will increase, and the engine will work normally.

However, the width of the computer adjustment is limited, and it cannot be adjusted after adjusting to the maximum width. In this case, if the carbon deposit continues to increase, various symptoms will appear and must be cleaned up. At this time, if the carbon is deposited by flushing, the gap between the nozzles will become larger, but the engine computer is a gradual long-term adjustment process, and the reaction is not so fast.

The injection time is already as long as when carbon is deposited, and the injection volume will increase.

The mixture is always in a relatively concentrated state, and some fuels are discharged without complete combustion, and fuel consumption may increase. After using it for a while, running about a few hundred kilometers will return to normal. This time period has to wait. Unable to use decoder.

Initialize the nozzle. Frequent cleaning is also piled on the throttle.

If the pores are clogged by carbon deposits, the throttle will automatically increase the openness to ensure idling.

inflow. There is also an adjustment limit that cannot be adjusted after the upper limit is reached. At this time, symptoms appear, the idle speed is unstable and severe, and the engine fault light is on.

After cleaning, the air hole will also become larger, the air intake will also increase, the idle speed will become higher, and you can also carry out serious 2000-3000 rpm, and you can't use a normal car, so you can't wait for self-study on the computer.

The reason is that the carbon deposits in the intake valve are not cleaned, the carbon deposits are in a hard state, and the intake valve cannot be closed normally and cannot be boarded. In other words, the surface of the intake valve is uneven, and it can be closed smoothly and firmly when there is carbon deposit. Half of the carbon is washed, the other half is on top, and the half of the wash has holes and cannot be closed.

So sometimes after washing the carbon deposits, the car seems to be more shaky than before. It seems to be caused by not washing it clean. Pull up the speed immediately and the airflow will improve significantly.

This is because a lot of the carbon deposits that have not been washed have become soft and can be washed away by high-velocity air currents.

Troubleshoot the reason for the accessory.

Specific solutions to idle jitter:

1. The engine has serious carbon deposits. The most common cause of idle judder is excessive carbon build-up on the throttle or injector. When there is too much carbon deposit inside the engine, the gasoline sprayed by the fuel injector during cold start will be absorbed by the carbon deposit, resulting in a mixture that is too thin and making it difficult to start.

After landing, the gasoline adsorbed on the carbon deposits will be sucked into the cylinder by the engine and burned, which will thicken the mixture. The mixture is sometimes dilute and sometimes thick, which will cause idle jitter after cold start. The lower the temperature, the greater the amount of oil required for cold starts, and the more the presence of carbon deposits affects cold starts.

The solution is to clean the carbon deposits at the throttle and injector.

2. Poor ignition system and poor ignition of spark plugs will also lead to engine idling and shaking. If there is a problem, check if the ignition system is faulty and if there is too much carbon deposited in the spark plug.

3. The oil pressure is unstable. If you have cleaned the engine carbon deposits, cleaned the throttle valve or replaced the spark plug, and there is still the problem of body shaking when idling, it is recommended to go to the 4S shop to check whether the fuel supply pressure and intake pressure sensor are normal. If the oil pump supply pressure is not normal or the intake pressure sensor is incorrect, it can also cause the body to shake when idling.

The best way is to clean the oil circuit, clean it regularly, there is no specific experience in the research and development parameters of the clean engine from the new car, coupled with the continuous improvement of emission standards, can not adapt to the change of fuel, all manufacturers of the engine are unable to solve this jitter problem in the short term, plus the fuel quality is not very good or the initial fuel of the new car factory is stored for too long, resulting in a rapid increase in the colloidal composition of the oil circuit, which will continue to pollute the fresh fuel and cause no good fuel to participate in combustion in the later stage. The occurrence of excessive carbon deposits is especially common for China VI vehicles. We can only gradually alleviate most of the problems by maintaining clean oil circuits. The use of PNF dope fuel additives can solve the problems caused by carbon deposition.

That's not because of the area of carbon in the engine, it's because of the engine's wiring problem, because the contact is poor or the wiring is broken, so there is no way to connect with it.

Because this is because it is not completely cleaned, there is still residual carbon in the engine, so it still shakes.

It's probably because you didn't clean up the carbon deposits when you cleaned them up, so this happens.

Engine shake after cleaning carbon deposition Causes of car shake after cleaning carbon deposition: 1. When carbon deposition adheres to the intake and exhaust valves, the intake and exhaust valves are not closed tightly and the air leaks, and the pressure in the engine cylinder drops, and the direct result is that the engine is difficult to activate, and there is shaking under idle conditions; At the same time, it affects the section of the mixture entering the combustion chamber, and the carbon deposition can adsorb a certain amount of mixture, thereby reducing the engine power; 2. When the carbon deposit adheres to the cylinder and piston top, it will reduce the volume (space) of the combustion chamber and improve the cylinder compression ratio, and when the compression ratio is too high, it will cause the engine to burn prematurely (solid engine knocking) and reduce the power generation; 3. When the carbon deposits adhere to the spark plug, it affects the quality of the spark; Not even jumping fire; 4. When carbon deposits are formed between the piston rings, it will easily jam the piston rings, causing fuel oil and straining the cylinder. @2019

Too much carbon deposition in the engine is easy to block the oil channel, the oil channel is blocked in the engine and there is a lack of lubrication, the friction between the piston and the cylinder block can not be effectively lubricated in the driving, the car will shake and weaken, affecting the normal driving, then it is necessary to overhaul the engine to solve the problem! Carbon deposition may indeed cause engine shaking, but this needs to reach a certain level, not a little carbon deposition will appear shaking, many engines are burned oil overhaul and there is no shaking, so there is no need to worry about the sky, <>

The main accessories of the ignition system are the spark plug and the ignition coil (of course, the high-voltage wire connected to the ignition coil is also counted). When starting cold, the temperature of fuel and various lubricants is also low due to the low temperature inside the engine. It may lead to vehicle shaking, and vehicles using fuel engines will inevitably produce carbon deposits, which will not affect the normal operation of the engine when the carbon deposits are light, and will lead to a series of problems such as a decrease in engine power, an increase in fuel consumption and an increase in exhaust pollutant emissions.

The main reasons for the formation of motive carbon deposition are as follows: First, the use of oil products with purity and quality that do not meet the requirements. The second is long-term idle operation and low-speed driving.

Third, due to the ignition time, spark plug and poor sealing of the cylinder block and other technologies or components are not operating properly. Carbon deposits to a certain extent can indeed cause the vehicle to shake. Any car will have carbon deposits after a period of use, and a slight carbon deposit will not affect the performance of the car.

The impact of carbon deposition on automobile engines is still quite large, and the main reasons for carbon deposition are poor oil products, congested road surfaces, stop-and-go, etc.

Therefore, it is necessary to run at high speed on a regular basis, or increase the engine speed in neutral gear, and add some regular fuel cleaning agent. When we start the car in the morning, the carbon deposits will absorb the gasoline we have just injected into the engine cylinder, so the car with serious carbon deposits is very prone to start difficulties when starting in the morning, which is due to the fuel just injected into the engine is sucked by the carbon deposits.
