What are the reasons for increased fuel consumption after replacing spark plugs?
1 Answers
The reasons for increased fuel consumption after replacing spark plugs are: 1. Incorrect spark plug model; 2. Spark plugs were not tightened properly during installation. The function of automotive spark plugs is to discharge the pulsed high voltage electricity delivered by the high-voltage wires, breaking down the air between the two electrodes of the spark plug to generate an electric spark, thereby igniting the air-fuel mixture in the cylinder. Precautions for using spark plugs: 1. Clean carbon deposits promptly; 2. Avoid prolonged use; 3. Avoid random descaling; 4. Avoid using fire to remove carbon deposits and oil stains from the spark plug electrodes and skirt; 5. Avoid using the wrong heat range of spark plugs; 6. Avoid over-tightening during installation.
