The role of spark plugs:

The spark plug is an important part to keep the car engine working. The gasoline engine generates power through the timely combustion of fuel and mixed gas, but the gasoline used as fuel is difficult to spontaneously ignite even in a high temperature environment. It is necessary to use it to make it burn in time. "Fire" to ignite. The role of the spark plug is revealed at this time. It uses a high-voltage discharge to create a high-energy arc that burns engine fuel. The quality of the spark from the spark plug determines the degree of combustion of gasoline in the engine, which in turn affects the performance of the engine.

Structure of spark plug:

The structure is not complicated and the purpose is single. In the ignition system of a gasoline engine, a high-voltage current is introduced into the cylinder to generate an electric spark to ignite the combustible mixture. The spark plug is composed of wiring nut (terminal screw cap), insulator, ceramic resistor, main metal part, center electrode, side electrode and other components, and the side electrode is welded on the shell.

Spark plug life:

Generally speaking, the service life of ordinary spark plugs (nickel alloys) is 20,000 to 30,000 kilometers, while the service life of precious metal spark plugs (platinum, iridium, etc.) can reach 60,000 to 100,000 kilometers. Of course, these replacement cycles are only under normal circumstances. In theory, the specific replacement cycle depends on the use of the vehicle. The owner can judge the use of the spark plug by changing the state of the vehicle.

How to check the status of spark plugs:

Remove the spark plug, check the color of the spark plug, the gap between the electrodes, whether the gap between the porcelain body and the metal shell is leaking, etc. If the vehicle is difficult to start from cold, there is obvious frustration in driving, idling jitter, and the speed-up performance is reduced, it is necessary to consider whether it is time to replace it.

Can expensive spark plugs improve power performance?

A car owner has done such an experiment. When the car owner replaced the original spark plug after driving 20,000 kilometers, he heard from a friend that the iridium spark plug can improve the power performance of the car, so he couldn't resist the temptation and spent "big money" on it. My car was replaced with a set of iridium spark plugs. After replacement and use, the car owner feels that the acceleration performance of the car has not improved. Why? The help of the spark plug to the power performance also depends on the engine itself. If the engine performance does not reach a certain "level", installing a more advanced spark plug will not help the power performance much.

Spark plugs require grease:

The role of grease on spark plugs: anti-sintering, anti-arc fallback.

When the engine is working, the spark plug will generate a high-energy arc to ignite the mixture in the cylinder in a timely manner. The heat of the high-voltage arc and gasoline combustion will be transferred to the ignition coil through the spark plug. Over time, the ignition coil will sinter with the spark plug, causing damage to the ignition coil and damaging the ignition coil. At this time, a high temperature grease is required to prevent the sintering of the spark plug and ignition coil. The high-voltage arc of the spark plug sometimes falls back, and the sealing effect of grease and insulation are required to prevent the fall of the arc.

Fokker spark plug grease:

The application of grease on spark plugs meets customer life test requirements. Grease has good high temperature resistance, does not corrode metals, has good compatibility with rubber, effectively prevents ignition coil sintering, and has excellent electrical insulation properties.
