What Causes High Fuel Consumption in Cars?

[LeAriel]

High fuel consumption is caused by carbon deposits. Below is an introduction to the causes and hazards of carbon deposits: Causes of Carbon Deposits: When a car runs for a long time, carbon deposits in the intake tract, valves, and combustion chamber increase. These deposits absorb fuel when the engine is cold and release fuel when the engine is hot, leading to difficulties in cold starts and higher fuel consumption when the engine is warm. This results in degraded engine performance, manifesting as idle shaking, poor acceleration, increased fuel consumption, and excessive emissions. At this point, it is necessary to clean the carbon deposits in the combustion chamber. Hazards of Carbon Deposits: Severe carbon deposits in the combustion chamber can raise its temperature, causing the air-fuel mixture to self-ignite simultaneously with the spark plug's ignition. The two ignition points create a sudden increase in cylinder pressure, damaging internal engine components and producing a knocking sound similar to hitting the cylinder block. This phenomenon is known as engine knocking.
