Is there any harm to the car if there is carbon deposit in the oil circuit of the car?

First, the disadvantages of inferior gasoline and the countermeasures to reduce the harm.

The second is when cars need to clean up carbon deposits.

China's crude oil is generally high wax crude oil, and the wax content in crude oil is basically in the range of 15%-20%. However, the wax content of Iraqi high-quality crude oil can only be determined at -30℃.

In this way, domestic gasoline will inevitably contain more long carbon chain components that are not easy to burn completely. This is what we usually call inferior oil.

What kind of influence will domestic inferior oil products bring to our cars?

The long carbon chain components in (1) gasoline are not easy to burn fully, and it is easier to form various carbon deposits.

The present situation of gasoline in China determines that we must have a more detailed automobile maintenance plan in order to fully eliminate the influence of various carbon deposits on the automobile condition. One of the easiest things to do is to drive at high speed regularly. Make full use of higher speed, higher cylinder pressure and higher ignition temperature to burn the carbon residue left by long-term low-speed driving at the top of the city as much as possible.

Generally speaking, driving at high speed for more than 20 minutes every month is very beneficial to maintaining the condition of the car.

(2) Long carbon chain components in gasoline that are not easy to burn fully-it is easier to hang on the throttle to form gel, thus blocking the throttle.

This, influenced by temperature, will be more intense.

When the temperature is low in winter, the bad long carbon chain components in gasoline are more likely to form knots. It leads to a series of car condition problems, such as difficult ignition, idling jitter, weak acceleration, increased fuel consumption and increased carbon deposition.

Especially for engines with more cylinder top doors, higher compression ratio and higher requirements for intake, exhaust and ignition timing, its influence is greater.

Therefore, the engine of 16V should develop the good habit of cleaning the throttle regularly. Especially before winter, it is better to do a cleaning, which is more beneficial to the maintenance of the car condition.

Many car supports, with some one-sided engine knowledge, maliciously attack sagitar, golf, Bora, 206 and other cars why they are still equipped with eight-valve engines.

In fact, a serious manufacturer has many factors to consider when choosing what kind of engine. Why are millions of kilometers of engines that have not been overhauled in Shenlong Factory maliciously attacked by ignorant motorcycle stalls?

The latest generation Mazda VI also reduced its engine compression ratio to 9.7. It fully reflects the determination of the manufacturers to build a good car that is more suitable for China's national conditions and can make everyone use it with more peace of mind.

(3) The long carbon chain components in gasoline that are not easy to burn fully-make the actual work value of gasoline greatly influenced by temperature.

After testing, the octane number of inferior gasoline in China, which is used to assess the actual work capacity of gasoline, changes as high as 0.4 with temperature.

In other words, the actual working capacity of the No.93 gasoline you added at bad temperature is only equivalent to the No.89 gasoline (even the No.90 gasoline can't reach it).

Now you can begin to know why there are so many strange phenomena in your car when it changes with the weather.

It is not difficult for us to know why those cars with old engines, which are not in the eyes of network "experts" and "masters", can still occupy the top positions in China's automobile sales rankings for a long time.

Ordinary people can ignore your hype data. In a few years, it will naturally depend on whose car is resistant to running.

(4) Oil temperature-one of the abnormal functions of inferior gasoline.

On the first day, the car was in good condition and in high spirits. The next morning, the ignition failed once.

This is the biggest influence of oil temperature on vehicle condition and performance. There has been a special article to discuss it, so I won't go into details.

(5) Oil temperature-the second abnormal influence of inferior gasoline.

Go to work in the morning and the car is in good condition. But in the unit parking lot until noon, the car shook violently after ignition. Is it a car? No, this is also a trick of oil temperature.

(6) Oil temperature-the third abnormal influence of inferior gasoline.

Perhaps, few people come across such a story, but one of our riders did.

Cheyou: Running on the highway that day, the car obviously felt boring at the end.

Me: Is the oil running out?

Cheyou: The fuel gauge light is not on yet.

Me: Just refuel.

Cheyou: I waited for a few minutes to get on the highway after refueling, and I felt that the car was strong again. Why?

Me: Oil temperature.

Let's find out more detailed reasons, which may be more helpful for our own car maintenance.

(a) The gasoline pump in the gasoline tank relies on gasoline to dissipate heat. The less oil there is in the gasoline tank, the heat generated by the gasoline pump is certain, which will inevitably heat the oil temperature higher.

(b) At high speed, the engine will inject more oil per unit time than at low speed. In other words, the gasoline pump must provide more oil per unit time, and the product must be that the gasoline pump generates more heat per unit time. So when driving at high speed, the oil temperature will be higher than usual.

The rider's "oil meter light is not on yet" just shows that he is running out of oil in the tank at high speed, so the oil temperature must be very high.

(c) Engine fuel injection is injected by volume.

Thermal expansion and cold contraction. It will inevitably lead to the same volume of gasoline. When the oil temperature is high, it contains fewer molecules. That is, the lower the total combustion value. Natural cars feel boring.

However, the oil in the gas tank of the gas station is cold. After adding cold oil, the natural car feeling is strong.

In fact, careful TX will have such an experience: the car that just finished refueling obviously feels more energetic, which is the influence of oil temperature.

Of course, there is a more careful TX, and the car at night is better than during the day. This all involves the know-how of oil temperature.

(7) Long carbon chain components that can't be completely burned in gasoline-refueling story:

The proportion of long carbon chain components is greater than that of short carbon chain components. Therefore, if gasoline is stored in the fuel tank of a gas station for a long time, the long carbon chain will precipitate.

This is what we often say: no priming.

Because the concentration of long carbon chain components in those gasoline is much higher than that in ordinary gasoline.

There is also: the gas station just finished filling up and can't add gasoline.

Because, when refueling, the impact will turn up the bottom oil that has been deposited at the bottom of the fuel tank for a long time, and then refuel after these bottom oils have sunk.

Therefore, choosing a more suitable time to refuel is not only of great benefit to the car condition, but also the light gasoline on the fuel tank is easier to burn fully, which will greatly improve the fuel consumption per 100 kilometers.

So when should we refuel?

Generally, most gas stations are filled with oil at night 10 to 12. In this way, after a night of precipitation, the oil in the early morning of the next day is the best.

Of course, as for the gas station in front of your house, you can only study it carefully by yourself. You can try it in the morning, noon and night. Try a few more times and you can try out the best time to refuel.

I had a strange oil temperature experience.

When there are two tanks left in the high-speed fuel tank, enter the rest area to refuel.

I just walked less than ten meters after refueling. My uncle wanted to buy something to drink and put it in the car, so he turned off the engine, got out of the car, went into the supermarket and bought water.

There was an ignition when getting on the bus, and the car was idling.

Turn off the engine immediately. After passing the self-inspection, step on the brakes with both feet, then ignite, and the jitter disappears.

Because the oil in the oil pipe is still hot just after filling, the ignition oil temperature is consistent with the memory of the EFI engine. After moving ten meters, the engine stopped and then ignited. At this time, the cold oil in the fuel tank came up, and the EFI engine remembered the state of hot oil, which led to the engine idling jitter.

Therefore, when buying a car and driving in China, we should keep in mind sixteen words-learn oil products, understand oil products, adapt to oil products and cooperate with oil products.

The second is when cars need to clean up carbon deposits. Let's talk about the process of carbon deposition first: the engine of a car is a four-stroke internal combustion engine, which needs air intake when working. When the air enters the intake manifold, it will mix with the atomized gasoline sprayed by the injector. During the mixing process, both air and gasoline will contain other impurities, which will be deposited in the intake manifold, especially in the throttle body. As long as you drive for a certain time or kilometers, carbon deposition will occur. Generally speaking, when the vehicle travels about 20,000 kilometers, the carbon deposit must be cleaned up once. If the carbon deposit is not cleaned up in time, it will accumulate thicker and thicker, and finally the engine will be in poor condition, such as engine weakness, trembling, difficulty in starting, and even shorten the engine life.

If you love your car, it is recommended that friends who have a car clean it every once in a while. It must be good and harmless! Excessive carbon deposition will block the oil circuit and hinder the normal oil supply; It can also lead to organic carbon impurities in lubricating oil. When lubricating the piston, impurities in the lubricating oil will rub the piston, thus damaging the piston of the cylinder. The engine will damage the heart and piston of the car, so how can it work normally? Hmm. How interesting
