There is a bit of carbon around the throttle, and there is no need to clean the engine

In the process of driving the car, over time, carbon deposits will inevitably appear on the engine, which is also a normal phenomenon that is often encountered in daily life. The consequences of such a phenomenon can be large or small, so it should not be taken lightly. Once the car has too much carbon deposit, it will not only increase the fuel consumption of the car but also affect the exhaust emissions, which will have a great impact on the environment, and in serious cases, the car will not be able to pass the annual inspection.

Since carbon deposition in automobiles is an unavoidable normal phenomenon, there is no need to worry too much about carbon deposition when it is not serious, but when there is too much carbon deposition, then it is worth paying attention to. It is obviously not advisable to blindly choose a cleaning item that has little effect for the car, and sometimes it will cause damage to the car parts. Therefore, how to do the correct and effective removal of carbon deposits in automobiles, the following tips can help you:

1.Cleaning the throttle valve can be said to be a maintenance item that many 4S stores generally recommend to do. In fact, a project that costs 100 yuan can be solved at a cost of only 10 yuan.

The method is as follows: after removing the throttle and engine trim cover, clean it with carburetor cleaner, and then dry it with a cotton cloth, the procedure is quite simple. 2.

Cleaning the carbon deposits inside the engineThe carbon deposits inside the engine can be effectively and thoroughly cleaned, which can not only reduce the pollution of the ambient air, but more importantly, prolong the service life of the engine. Then, the method is: after opening the oil cap, pour a bottle of engine internal cleaner into the oil port, then turn off the ignition for about 10 minutes, and finally replace the engine with new oil and filter.

The most important thing is that the cleaning cost will not be very high, far lower than the maintenance project cost in the 4S shop, which saves a lot of money for the car owner. 3.Cleaning oil circuit carbon deposition is not a complicated job for cleaning oil circuit carbon deposition, and the effect of thorough cleaning can be achieved without disassembling any car parts.

The method is: before refueling, the owner only needs to pour a special cleaning fuel additive into the fuel tank of the car, and the oil circuit of the car can be thoroughly cleaned. It is worth noting that when you buy a cleaning agent, you must pay attention to it and never choose the wrong one.

At the same time, car owners should also carry out regular maintenance and inspection of their cars, reduce the number of visits to 4S stores, and save a lot of money for their wallets.

Carbon deposits in the engine are normal and there is no need to clean the engine.

It's not the same thing. To clean up the carbon deposits, you should clean the combustion chamber in the cylinder. Generally, it is to clean the fuel injector, valve, spark plug, piston ring in the cylinder, piston skirt and other pulsation foci. The throttle valve is a part of the cleaning, but it is only a part of the cleaning of the engine's carbon deposits.

The combustion chamber is prone to carbon deposition, which will lead to difficulty in starting, and the carbon deposition of the injector will also lead to the blockage of the oil circuit, the gasoline injection will be deformed, the atomization is not good, and the fuel consumption will naturally increase. There are many reasons for the formation of sludge at the throttle, some of which are the formation of carbon deposits at the throttle by the exhaust gas of fuel combustion; That is, no impurities filtered by the air filter remain on the throttle. If there is too much oil, the intake air will create air resistance, resulting in increased fuel consumption.

Normally, there are two ways to clean the throttle valve, dismantling and non-dismantling cleaning. The former is to remove the entire throttle assembly, and then thoroughly clean it with a special cleaning agent before restoring it. Although this method is troublesome, it is better than a complete cleaning.

In the latter case, scrubbing the throttle by spraying the throttle cleaner directly on the wiping cloth is relatively simple and convenient. There is no strict limit on the frequency of cleaning the throttle, which has a lot to do with the car habits and environment. Phenomenally, when the idle speed is unstable, cleaning should be considered.

Removing carbon deposits is more than just cleaning the throttle. Removing and washing the engine is the most effective way to remove carbon deposits, not only from the cylinders, but also from the valves and pistons. But the cost is too high and it takes a long time.

When the spark plug is used for a certain period of time, the carbon deposit in the engine will increase, and the ablation of the electrode will also lead to the increase of the electrode gap, which will cause insufficient combustion, engine power attenuation, and fuel consumption increase. In particular, the sulphur content of domestic fuel is generally too large, which puts a heavier burden on the spark plugs, so it is very wise to replace the spark plugs regularly.

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 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.

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 non-corrosive, will not clog ternary, and have a relatively high level of safety.

There are a lot of car maintenance items, if the correct maintenance of their car, is also what every car owner wants to do, then cleaning the throttle and cleaning up carbon deposits is the same thing?

Cleaning the throttle is not the same thing as cleaning the carbon deposit, cleaning the throttle is only a part of cleaning the carbon deposit of the engine, and cleaning the carbon deposit is the cleaning of many parts of the combustion of the engine cylinder, including the throttle. In addition to this, cleaning engine carbon deposits will also clean fuel injectors, spark plugs, valves, piston rings, piston skirts, etc.

There are two ways to clean the throttle, you can remove the throttle for cleaning, or use a rag dipped in cleaning agent to wipe the throttle, usually the former is more thorough and the effect is better. There is no strict requirement for how often the throttle of the car should be cleaned, and if the car is unstable at idle, the throttle needs to be cleaned. The vehicle can clean the throttle separately or at the same time as the engine carbon deposits.

OK. The main purpose of cleaning the throttle is to remove the carbon deposits on it, and the user can use a special throttle cleaning solution or chemical detergent. The cleaning principle of this type of cleaning agent is to dissolve carbon deposits, and its composition is more harmful to the human body, so it is best to wear gloves and masks when cleaning.

Spray the cleaner onto the throttle where there is a lot of carbon deposit, and wait for it to dissolve for about 5-10 minutes.

Using a brush will speed up the removal of carbon deposits. Once you see that the stain on the throttle has completely dissolved, you can use a clean towel to wipe off the detergent inside the throttle.
