What Are the Hazards of Engine Carbon Deposits?
1 Answers
Engine carbon deposits can cause the following hazards: 1. Reduce engine power and increase fuel consumption. 2. In severe cases, it can cause engine knocking, acceleration noise, damage to pistons and crankshafts, and even lead to engine oil burning, requiring major repairs. 3. It directly affects the vehicle's exhaust emissions, making it unable to pass annual inspection tests. Below are methods to prevent engine carbon deposits: 1. Avoid prolonged idling: Long idling time increases the time needed for the engine to reach normal temperature, slowing the evaporation of gasoline sprayed onto the back of the valves, leading to carbon deposits. Frequent idling also reduces the airflow into the engine, weakening the scouring effect on carbon deposits and promoting their accumulation. 2. Pay attention to the timing of engine shutdown: For vehicles equipped with turbochargers, do not shut down the engine immediately after high-speed driving or climbing. Let the engine idle for 10 minutes before shutting down. Turbocharged vehicles accumulate carbon deposits several times faster than naturally aspirated vehicles. It is recommended to perform a non-disassembly cleaning of the intake system every 20,000 to 40,000 kilometers under normal maintenance conditions, cleaning carbon-prone areas such as the intake tract, valves, and fuel system.
