Why is the car lacking power and consuming more fuel?
1 Answers
Possible reasons include filling the car with poor-quality gasoline, issues with spark plugs or ignition coils, aging of the fuel pump, or a clogged air filter. Here are the details: 1. Spark plugs: The function of a spark plug is to discharge the high-voltage pulse electricity sent from the high-voltage wire, breaking down the air between the two electrodes of the spark plug to generate an electric spark, thereby igniting the mixed gas in the cylinder. 2. Fuel pump: The fuel pump is a lightweight and compact pump, mainly categorized into in-line, distributor, and single-unit types. The fuel pump requires a power source to operate; the camshaft at its lower part is driven by the engine crankshaft gear.
