Does the quality of spark plugs affect fuel consumption? How often do spark plugs need to be replaced?

Does the quality of spark plugs affect fuel consumption? Nature has an impact and possesses key hazards. The engine has a major impact on fuel consumption, and the spark plug is the ignition system of the engine, which determines whether the gasoline can be burned adequately. The more sufficient the combustion, the stronger the driving force, the greater the efficiency, and the natural fuel savings. Below, I will briefly talk about spark plugs and fuel consumption for your reference. Generally, we all know that the engine is the "cardiovascular" of the car, and the spark plug is the "pacemaker" of the engine, which continuously ignites the engine, allows the gasoline to burn and work, and promotes the operation of the car. At a glance, it seems to be somewhat the same as the rectifier of a gas stove.

The gas stove only needs to be ignited once, but the spark plug needs to be interrupted pulse ignition (that is, continuous intermittent ignition). A normal four-cylinder engine requires four spark plugs because each cylinder performs the steps of intake-contraction-ignition-expansion-exhaust pipe independently. Each step requires a spark plug to ignite the fire, and the cycle repeats endlessly.

The level of the flame each time the spark plug fires will directly depend on whether the combustion is good, whether the time of each firing is appropriate, and whether the time period of the combustion is Effective, and the conclusion of combustion will directly affect the driving force and fuel consumption of the engine. The spark plug is responsible for causing fire. The fuel consumption of an engine depends on its efficiency, and its efficiency depends on whether the cylinder pressure reaches the standard, whether the proportion of flammable gas mixture is the best, whether the flame intensity generated by the spark plug is sufficient, and whether the ignition is correct. The timing is accurate and other major factors, so the spark plug not only has an impact on the engine's fuel consumption, but also has a relatively large impact.

At the end of the engine's compression stroke, the spark plug ignites. Later, the engine will enter the power stroke. The ignition time of the spark plug and the ignition kinetic energy are directly related to fuel consumption. If the ignition time and ignition energy are not up to standard, it will cause insufficient engine combustion, which will directly lead to an increase in engine fuel consumption and a decrease in power response. After the spark plug is used for a period of time, it will be damaged. If the electrical gap is too large, it will particularly affect the ignition quality. Therefore, most automobile manufacturers have clear instructions on the spark plug replacement cycle for their products.
