Without disassembling the engine, how can we know whether the car is seriously carbon-deposited?

How to know whether there is serious carbon deposit in the car without disassembling the car engine can be carried out from two aspects. The first is to look at the tail of the car exhaust pipe. If there is a black substance at the tail, it means that the car engine has serious carbon deposition. On the other hand, you can look at the accelerator of the car. If you turn on the throttle and find that there is more black matter in it, it means that the engine has a lot of carbon deposits.

First, you can check the exhaust pipe of the car.

Exhaust system is a very important accessory of automobile. Because the exhaust pipe of the exhaust system is connected with the engine, the harmful gas generated by the engine will be transported to the exhaust pipe after three-way catalytic filtration. The owner touched the exhaust pipe mouth with his hand and found that there were many black substances on his hand, which proved that the engine had serious carbon deposition, because after the engine produced carbon deposition, the gas produced by carbon deposition would be transmitted to the exhaust pipe, which directly proved that there was a lot of carbon deposition inside the engine. Second, you can look at it from the throttle.

The automobile throttle is installed at the air inlet of the automobile. Cars are generally located on the right side of the engine and connected to the air filter element. When the owner opens and removes the throttle, he can use the heat source for inspection. If there is a lot of black matter in the middle of the throttle, it means that there is still a lot of carbon deposit inside the engine. After all, this position belongs to the air intake, and a large amount of carbon deposits in the engine will attach to it. Third, summary.

Generally speaking, if you don't disassemble the engine, you can determine whether the carbon deposition inside the engine is serious by looking at the exhaust pipe and throttle of the car. When the carbon deposit in the car is serious, it will affect the power and fuel consumption of the car, so the owner must go to a professional car repair shop for inspection and maintenance in time to ensure the working state of the engine. If the engine carbon deposits accumulate over time, it will inevitably shorten the service life of the automobile engine and greatly increase the cost of the owner's car.
