What are the effects of carbon deposits on a car?
1 Answers
Effects of carbon deposits on a car: Causes poor engine performance, leading to difficulties in starting, unstable idling, poor acceleration, backfiring during rapid acceleration, excessive exhaust emissions, increased fuel consumption, and other abnormal phenomena. Carbon deposits refer to a mixture that accumulates on the engine's valves, combustion chamber, and intake pipes. Carbon deposits are formed when the engine's fuel does not fully burn, resulting in the formation of hydrochloric acid and resin-like gums under high temperature and oxygen catalysis, which adhere to the surface of parts. Further high-temperature action concentrates these into complex mixtures such as asphaltenes and oil coke. Methods to prevent carbon deposits: 1. Use high-quality gasoline: Waxes and gums in gasoline are the main components that form carbon deposits. Gasoline with high cleanliness has a weaker tendency to form carbon deposits. 2. Avoid prolonged idling: Long idling times extend the time it takes for the engine to reach normal temperature, slowing the evaporation of gasoline sprayed onto the back of the valves, leading to carbon deposits.
