Six methods to prevent carbon deposition

Six methods to prevent carbon deposition

1, clean the air filter frequently.

Don't often run on dusty roads, and often clean the air grid (air filtration), which can also play a role in reducing carbon deposition. Every 20,000 kilometers, it is best to replace the air cabin and clean the fuel injector and throttle.

2. Idling for a long time and turning off the air conditioner will cause carbon deposition.

Don't let the vehicle idle for a long time, especially don't turn on the air conditioner for a long time. When the water temperature is between 85℃ and 90℃, the engine is in the best working state, otherwise the gasoline will not burn fully and there will be more carbon deposits. From this point of view, if the car is heated for a long time in the morning, the engine temperature will rise slowly, which will also cause carbon deposition. Running the air conditioner at idle speed will bring more load to the engine. If it only takes a few minutes to wait for someone, there is no need to turn off the engine. Because at the moment of restart, not only the fuel consumption is high, but also the engine will wear out.

3. High-speed running can wash away carbon deposits.

High-speed running can really use airflow to scour the airway and wash away some carbon deposits. So, if you happen to have two choices when you go out, you might as well choose to take the expressway once. But if you run the highway specifically to "wash away the carbon deposits", it is unnecessary. Waste time, waste oil, waste high-speed tolls. The effect is not as good as going to a 4S shop for maintenance!

4, improve the shift speed, prevent carbon deposition, and protect the engine.

Low-speed gear shifting, also known as "gear shifting", is easy for cars to knock, and insufficient gasoline combustion leads to carbon deposition. But there is no need to artificially increase the shift speed-this will increase fuel consumption and cause premature wear of clutch friction plates. Therefore, the manual transmission car has a displacement of 1.6 ~ 2.0L, which is more economical and practical, and there is no need to improve it; For automatic cars, be careful not to slam on the accelerator.

5. When the car is parked, can the carbon deposit be washed away like running at high speed by hanging the neutral throttle?

Theoretically, slamming on the accelerator at idle speed will wash away some carbon deposits, but this method is not recommended. The first is to waste gasoline and pollute the environment; Secondly, idle speed is not good for the engine. Especially when the speed reaches more than 4000 rpm, if you don't run on the road, there is no wind blowing in to cool the engine, which will have an impact on the engine. If you really want to wash away the carbon deposits by airflow, get on the expressway!

6. The most effective and convenient way to remove carbon deposits.

Carbon deposition or prevention: don't use fake inferior lubricating oil, but go to a regular repair shop for maintenance. If you use inferior engine oil, you won't see the impact in a short time, but after a year or two, it will lead to serious carbon deposition and even damage to the engine.
