Low calorific value spark plugs are suitable for small horsepower engines with low rpm and low compression ratio
1. Spark plugs are divided into low calorific value spark plugs and high calorific value spark plugs. Different spark plugs are suitable for different engines, so we are careful when choosing. So let's see the circumstances under which low calorific value spark plugs and high calorific value spark plugs are suitable.
2. The temperature of the center electrode of the low calorific value spark plug is easy to change, the temperature is easy to increase, and the power used is small. It is suitable for certain low power engines. suitable for low speeds and low compression ratios. Low calorific value spark plugs clean themselves during use. The matSpark plug material is an insulator, which can easily clean the carbon produced by combustion and prevent carbon accumulation.
3. Unlike low calorific value spark plugs, high calorific value spark plugs are more suitable for high horsepower engines with high speed and high compression ratio. long lasting. It is a very suitable choice for people who need to run at high speeds and long distances for long periods of time due to work demands.
Additional:
When the temperature is lower than 5℃, a spark plug with lower calorific value should be used to ensure the working temperature of the spark plug skirt d 'ignition. For older engines, choosing a spark plug with a lower calorific value can cause oil leaks and contaminate the spark plug due to worn machine parts.
Notes on spark plugs: Do not use them for a long time, otherwise their service life will be damaged. Charcoal should be cleaned regularly to prevent carbon buildup. Do not descale at will. Pay attention to the cleaning method. The correct cleaning method is to pour gasoline into the spark plug and clean it with a brush. Do not use sandpaper, metal sheets, etc.
Different situations require different calorific values of spark plugs, so it is recommended to choose according to the conditions of your car when choosing, and not to install them blindly. Choosing the right one will be a boost for your car. Wrong choice will reduce the operating efficiency of the car, thereby affecting your journey.
In summary, low calorific value spark plugs are suitable for low power, low rpm and high speed engines.low compression ratio.
Why/principle why electromagnets and spark plugs cannot generate electricity
Spark plugs are a important part of automobile ignition system and operate in harsh high temperature conditions. temperature and high pressure, is 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 part intoporcelain towards the hull, 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 evidence of arc ablation requires replacement of the spark plug.
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 due to 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.
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, attractingt or thereby 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.
