Why is the car ignition not as crisp as before?

[VanPaige]

There are several reasons why a car's ignition is not as crisp as before: 1. Carbon buildup in the engine; 2. Weak spark plug ignition energy; 3. Insufficient fuel line low pressure; 4. Battery discharge. During engine operation, unsaturated olefins and gums in the fuel produce a coking-like substance under high temperatures, which is carbon buildup. Spark plugs, commonly known as sparkers, function by discharging the pulsed high-voltage electricity sent from the high-voltage wires (sparker 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. The fuel system of a turbocharged engine consists of components like the fuel pump, fuel filter, and fuel injectors to ensure the required fuel flow under various operating conditions. The battery generally refers to all chemical energy storage devices that can be recharged and reused after being discharged to a certain extent.
