What are the symptoms of excessive carbon deposits?

Symptoms of excessive carbon deposits: It will alter the original structural parameters of the engine, reduce engine power, increase fuel consumption, and in severe cases, it can also cause engine knocking, abnormal acceleration noise, damage to pistons and crankshafts, and even lead to engine oil burning, requiring major repairs. Methods to reduce carbon deposit formation in cars: 1. Use high-quality fuel, as the main components of carbon deposits are wax and gum deposits from the fuel, so the lower the gum content in the fuel, the better; 2. Avoid driving at low speeds for extended periods. If necessary, you can periodically drive at high speeds. The principle of high-speed driving to eliminate carbon deposits is to accelerate gas flow, which can remove a small portion of carbon deposits that are not firmly attached, and increase combustion temperature, allowing some carbon deposits in the cylinder to be burned.
I know exactly how carbon buildup feels. Last year after my car hit 50,000 kilometers, the problems started: severe engine shaking during startup that made the whole car tremble like an earthquake; noticeably weaker acceleration where pressing the gas pedal felt like stepping on cotton, with speed struggling to climb – overtaking became exhausting when it used to be effortless; fuel consumption skyrocketed from 8L/100km in the city to nearly 10L, hurting my wallet at every fill-up; unstable idle RPM with the needle bouncing around, sounding awful at red lights; and black exhaust smoke with a pungent plastic-burning smell that friends complained about. Prolonged carbon deposits don't just affect driving – they can wear engine components. I now do cylinder cleaning every two years and regularly drive at highway speeds, which helped significantly. Don't ignore these symptoms – early inspection saves major repair costs.
