Hazards of carbon deposition to the engine

The effect of engine carbon deposition on the car is significant. First and foremost, it is to reduce engine power, that is, to make power output uneven and gradually attenuate, in other words, to become less and less powerful. Second, increase your fuel consumption and thus your financial burden. Third, it is difficult to start the car from a cold start. Finally, severe carbon deposition in the combustion chamber will cause cylinder knock and noise when accelerating at low speeds, causing damage to the piston and crankshaft and jeopardizing vehicle safety.
Because the structure of carbon deposits is similar to that of a sponge, when a carbon deposit forms on the valve, a portion of the fuel injected into the cylinder is absorbed each time, causing the concentration of the mixture that actually enters the cylinder to become thinner, resulting in poor engine operation, such as difficulties starting, unstable idle speed, poor acceleration, flash fuel backfire, excessive exhaust gas, increased fuel consumption, and other abnormal phenomena. If the problem is severe, the valve will not close tightly, resulting in no cylinder pressure in the cylinder and a failure to function completely, and the valve will not return due to adhesion. At this point, the valve and piston will collide and eventually cause damage.
