There is too much carbon deposit. What's wrong with the car?
The following are the effects of more carbon deposits in cars: 1, and the acceleration of cars is poor. Carbon deposition reduces intake passage, cylinder pressure increase caused by inflation coefficient and engine power reduction caused by ignition time delay. 2. The vehicle is difficult to start. Carbon deposition falling into the intake valve seat passage will lead to insufficient cylinder pressure. When starting, the injected fuel is adsorbed by carbon deposits, which leads to the engine with lean mixture in the cylinder unable to start normally. 3. Engine idling is unstable. When carbon deposits are attached to the intake valve and throttle valve, the engine cannot accurately control the amount of gasoline and air sent into the combustion chamber, resulting in unstable engine speed. 4. Increased fuel consumption. When carbon deposits accumulate in the combustion chamber, it is easy to cause knocking, which delays the ignition time of the engine, reduces power and increases fuel consumption by 4~5%. 5. Exhaust emission exceeds the standard. Carbon deposition leads to an imbalance in the mixing ratio of gasoline and air, which leads to insufficient combustion of gasoline, an increase in the contents of CO and HC in tail gas, and the emission is not up to standard. 6. Engine failure. When carbon deposits are attached to the intake valve stem, it will cause hairpin bend between the valve stem and the guide pipe, which will cause the piston to hit the valve engine and cause damage to the intake valve and piston.
