What are the reasons for the sudden increase in fuel consumption of the Baojun 530?

[StEloise]

Engine carbon deposits, spark plug failure, and abnormal tire pressure can cause this. Specific reasons: Engine carbon deposits: During long-term operation of the vehicle, gasoline inevitably produces carbon deposits and sludge during combustion. If these deposits and sludge are not cleaned in time, they will lead to increased fuel consumption. Spark plug failure: The function of the car's spark plug is to use high voltage to generate sparks to ignite the air-fuel mixture. If damaged, it will reduce ignition energy, causing uneven combustion of the mixture, which will slow down acceleration and increase fuel consumption. Abnormal tire pressure: Incorrect tire pressure can also affect the car's fuel consumption. When the tire pressure is too low or the tread is severely worn, the contact area between the tire and the road surface increases, leading to greater friction, increased rolling resistance, and naturally higher fuel consumption. Solutions: Clean engine carbon deposits, replace or clean spark plugs, and check and replenish tire pressure as needed.
