1, when the carbon adhesion intake and exhaust valves, the intake and exhaust valves closed lax and even leak, the pressure drop in the engine cylinder, the result is a direct result of the activation of engine trouble, idling jitter; affect gas mixture into the combustion chamber cross section, can absorb some of the carbon mixture, thereby reducing engine power.

  2, when the carbon adhesion in the cylinder, the piston crown, it will reduce the volume of the combustion chamber (space) to improve the compression ratio of the cylinder, when the compression ratio is too high, it will cause the engine preignition (solid engine knock), motive power reduced .

  3, when the carbon adhesion spark plugs, spark affect quality; even without flash.

  4, when coke is formed between the piston rings, piston rings will be easy to get stuck, causing the fuel oil and strain the cylinder wall.

  5, when the carbon adhesion oxygen sensor, the oxygen sensor can not properly perceive the exhaust gas condition, air can not be adjusted correctly likelihood ratio, so that the engine exhaust gas exceeded.

  6, when the carbon deposits in the intake manifold is formed inside, the interior becomes more rough, affect the formation and concentration of combustible gas mixture.

  So. Regular cleaning is every car carbon owners must do homework, maintain the quality of the car engine work is done the car to maintain a very important aspect of maintenance. Proper vehicle maintenance will extend the life of the car's safety performance improve not only save money but also save a lot of car troubles, so the car lies "keep."
