What Happens If You Don't Replace the Car Fuel Filter?

[VanEthan]

The consequences of not replacing the car fuel filter are: 1. It will cause a decrease in fuel supply pressure, poor fuel atomization, leading to an imbalance in the air-fuel mixture ratio and incomplete combustion; 2. It will generate a large amount of carbon deposits, aggravating the clogging of the three-way catalytic converter and contaminating the spark plugs and front oxygen sensor; 3. It may result in misfiring symptoms, black smoke from the exhaust, leading to excessive emissions. The fuel filter, also known as the gasoline filter or fuel filter, functions to filter the gasoline from the fuel tank to the engine combustion chamber. Precautions to take when replacing the fuel filter include: 1. Replace it every 20,000 kilometers; 2. Avoid smoking and using open flames during replacement; 3. Replace it when the engine is cold.
