Touch the exhaust pipe and say it's getting dark
I also found an interesting news on the Internet. A gas station master, he used this routine. "Wow" went in and "gasped". I didn't expect that the exhaust pipe he inserted was a fake exhaust pipe that was later modified, and it was blocked and did not ventilate.
I was embarrassed to death when the owner found out. I didn't add any gas, so I changed to a gas station.
In fact, the inside of the exhaust pipe is black and completely normal. The top of that gas stove is also black, so it is impossible for gasoline to burn completely 100%. The company found 10 cars downstairs, and 10 cars were all black. That doesn't mean that the engine has a serious carbon deposit.
The fuel tank pressure is high and there is sound.
The second routine tells you that the fuel tank pressure is too high. Listen, listen, this tank is like coke when it is opened.
"Shh" is loud, isn't it? "Shh" is loud, isn't it? Colleagues in our unit have all encountered this situation.
The new car has just been mentioned for less than half a year, and the master ran over and said that the car was old and had carbon deposits. You see, when you open the tank cover, it starts to explode. You need to add 1 bottle of fuel treasure at one time.
If there is pressure in the fuel tank, the exhaust is normal. This is easy to happen, especially when the temperature is high in summer or the model of China 6B is relatively new. In order to protect the environment and save fuel, the design of the whole fuel system is different from the past, and gasoline vapor needs to be completely collected.
So occasionally there is pressure to vent, just like opening a coke, don't worry. Start all kinds of unnecessary pipes normally after refueling. Unless you can't start them, check the carbon canister, which has nothing to do with carbon deposition.
It is said that the tail gas smells bad and burns abnormally.
The third routine. "Tut-tut", the tail gas of your car seems particularly smelly and poisonous. Your engine is not burning properly, so you need to add fuel treasure.
This kind is also quite outrageous. First of all, the tail gas can't smell good.
Scientifically speaking, all kinds of volatile organic compounds in tail gas are irritating and unpleasant.
Usually, three-way catalysis will help us filter out most of the harmful gases, so the smell of tail gas is generally not obvious. If it really stinks, it can't be because of carbon deposition. It is very likely that there is something wrong with the three yuan.
Check whether it was stolen or broken. High fuel consumption and poor power. You can try fuel treasure. After all, gas station employees don't have perspective eyes, so there is no way to know whether the engine has carbon deposits.
The best tester is ourselves. If you go to work normally every day, it used to be around eight o'clock, but now it's 10.
We are the same, why is it that the engine is a bit stupid when you step on the accelerator deeply? This performance seems to be obviously not as good as the new car, which is a bit dull and stupid. In this case, you should consider checking to see if the car really has too much carbon.
What does carbon deposit look like?
If your car is really like this, and you want to solve it but dare not spend more money, then you can click on my homepage. Search for the word "carbon deposit" in the upper right corner. Look at the carbon deposit in the engine. I'll take a video for you, just like doing colonoscopy and gastroscope. Our pipe is plugged into this engine.
