Q1: What is the carbon deposit in the engine?
Carbon deposits in automobile engines are mainly caused by the fact that part of the fuel is not fully burned when the engine is working after driving. The colloids and hydrocarbons in the fuel become carbon deposits and attach to the cylinder. A lot of carbon deposits.
Q2: What causes the engine carbon deposit?
For example, when we were cooking in the countryside with firewood, when we burned firewood at home, we would leave a layer of ash at the bottom of the furnace. Engine combustion is the same as its principle, in simple terms, the result of insufficient combustion of the combustion materials.
Prolonged low speed, idle running or sudden acceleration of the accelerator will cause carbon deposits.
In general, the worse the quality of the oil, the easier it is for the engine to deposit carbon.
Q3: What are the hazards of engine carbon deposits?
- Carbon deposition in the engine will make the wall of the intake pipe rough, which will affect the intake effect and the quality of the mixed gas.
- It is also possible to change the size of the throttle channel, block the idle channel, cause the idle control device to stagnate or exceed its adjustment range, and cause unstable idle speed, flameout, excessive emissions, and increased fuel consumption.
[ Summary ] Because the internal structure of carbon deposits is similar to sponge-like, after the formation of carbon deposits in the valves, a part of the fuel injected into the cylinder will be adsorbed. The concentration of the mixed gas entering the cylinder becomes thinner, causing the engine to malfunction and start. Difficulties, engine overheating, knocking combustion, unstable idle speed, poor acceleration, rapid refueling and tempering, excessive emissions, increased fuel consumption and other abnormal phenomena.
Q4: How to prevent and clean up the engine carbon deposits?
- Don’t rush out after a long time driving. After stopping the car, let the engine run at idle for about 30 seconds and then turn off the engine can effectively reduce the carbon deposit of the engine.
- Cleaning the throttle is a practical little trick to deal with engine carbon deposits and is easy to operate.
- If you open the manual gear, pulling the high speed with no time has a great effect on the carbon deposition of the engine.
- The professional car maintenance industry uses two methods: one is to disassemble the engine and clean it with engine oil; the other is to apply high pressure to flush out the internal carbon deposits. However, cleaning the engine is expensive.
