Their principle is to carry out their functions through electrical principles. An electromagnet is a device that uses the magnetic field produced when an electric current passes through a coil to attract or repel iron or other magnetic materials. By passing electricity through the coil inside the electromagnet, a magnetic field can be generated around it, thereby attracting or repelling iron or other magnetic substances; a high-voltage arc forms between the two electrodes of the spark plug, causing combustion in the fuel; and a mixture of air, thus generating energy. Therefore, electromagnets and spark plugs do not generate electricity; they work by converting electrical energy into other forms of energy to perform specific functions.
Spark plugs are an important part of the automobile ignition system. They workin harsh conditions of high temperature and pressure and are one of the wearing parts of gasoline engines. So, what are the symptoms of a broken spark plug? When the vehicle is driven for a period of time, sediment builds up on top of the spark plug insulator and electrode, preventing the engine from operating properly. If the electrode is melted or removed, the spark plug must be replaced. Due to problems in the spark plug manufacturing process, the spark plug broke. The high-voltage electricity did not pass through the center electrode of the spark plug, but was directly discharged from outside the porcelain part to the shell, causing flashover. the surface of the porcelain part of the spark plug. There were obvious axial signs on the surface of the porcelain piece. Any trace of arc ablation requires replacement of the alloy spark plugmage.
If the car exhibits the following symptoms with a broken spark plug;
When the engine exhibits obvious abnormal vibrations during light acceleration, it is likely that the spark plug ignition is damaged. ?
While waiting for a red light, the car will feel obvious vibrations. If the engine vibrates significantly at idle, there may be a problem with the spark plug. It can also be caused by excessive carbon deposition.
If the engine is difficult to start, excluding common phenomena caused by seasonality or poor engine maintenance, then you can determine if there is a problem with the spark plug. But if the automatic shutdown occurs, it means that there is probably a problem with the spark plug of several cylinders.
The performance of spark plugs is linked to the working conditions and the efficiency of the entire vehicle.It is necessary to maintain and replace spark plugs in a timely manner. Be sure to choose the right model and pay attention to the choice of fuel for daily use. Poor quality oil will also affect the spark plugs and cause engine damage.
