What is spark plug

What is a spark plug? Spark plugs are critical to the ignition system of an automobile, which is the starting point for engine work. Therefore, the performance of the spark plug affects the performance and work efficiency of the entire vehicle. What do we need to pay attention to spark plugs? How long is the spark plug replacement cycle? How should we choose spark plugs?

Spark plugs are an important component of the car's ignition system. On gasoline engines, we can see that there are spark plugs on each cylinder. Some cars have high-speed engines. Each high-speed engine has two spark plugs on each cylinder. At present, we often use spark plugs platinum spark plugs, sheet metal spark plugs and resistance spark plugs.

What is the role of the spark plug? The function of the spark plug is to introduce tens of thousands of volts pulse generated by the ignition coil into the cylinder of the engine through the high voltage line, and ionize the air between the electrodes in a specific time to produce strong spark and thermal effect, which is to ignite the engine Necessary conditions for mixing gases in the cylinder.

Under normal circumstances, the common spark plugs on the market have a service life of 30,000 kilometers. If the spark plugs are made of precious metals, like platinum or sheet metal, the life cycle will be extended to 60,000 to 90,000 kilometers. The maintenance cycle recommended by car manufacturers of different models is different, and the specific replacement cycle we need to strictly follow the car manufacturer's requirements. Spark plugs for power engineering vehicles like Xiaobian's friends are replaced once every 30,000 kilometers.

Cautions for using spark plugs:

1, in the use of spark plugs will produce carbon deposition, too much carbon will cause the electrode leakage, etc., so the spark plug should be cleaned frequently.

2. The spark plug will be difficult to discharge after long-term use, affecting the work of the engine. After the spark plug has passed the shelf life, we must replace it in time.

3, do not use the fire method to remove the carbon deposition, the flame temperature is too high will lead to spark plug leakage, remove carbon deposition to use professional equipment.

4, when the car engine to replace the spark plug, choose the right model.

5, in addition to the shape and size of the spark plug is also divided into cold, medium and hot 3, we have to choose according to the car's situation.

6, in the installation of spark plugs, I pay attention to the installation of the force, too tight will cause the spark plug expansion fracture, too loose will lead to the engine does not work properly.

Ignite Status:

Comparing with normal spark plug, the flame od Iridium Spark plug spread more frequently. Iridium Spark plug improve much more the ignitability and fuel economy.

Improve Acceleration:

With the 0.5mm center electrode, the acclerating performance improves obviously. The time difference to speed up would be shortened 0.7 to 1 second.

Improve Engine Starting:

With the powerful ignitability, the Iridium Spark plug can ignite the engine easily and make less cut off even under thin air and adverse environment.
