Regular replacement can ensure more complete ignition, allowing the mixture to burn more completely, thus saving fuel if the mixture can be completely burned, the operating efficiency of the engine; will be high and the exhaust indicators are better.
There is also emphasis on how often a new car's spark plugs should be replaced. Generally speaking, each car manufacturer brand has its own recommended replacement cycle. The manufacturer of Guangqi Honda recommends not changing the replacement cycle before the launch of the new car. Spark plugs should be replaced every 100,000 miles and inspected during every major service.
Precautions for automobile spark plugs
In addition to different shapes and sizes, spark plugs are also divided into three types: fr typeoid, the medium type and the hot type. Generally, high compression ratio, high rpm engines should use cold spark plugs; Low-compression, low-rpm engines must use hot spark plugs, and there are mid-sized spark plugs in between.
In addition, the selection of spark plugs for new or overhauled engines and old engines may be different depending on actual conditions. For example, when the engine is newer, the spark plug should tend to be hot; In an old engine that has been used for a long time due to performance degradation, the spark plug is prone to excessive carbon deposits and oil contamination. The spark plug should be medium or cold to improve the quality of the spark plug.
How many kilometers should you replace the spark plugs ? What effects will replacing spark plugs have on the car?
How to install spark plugs in Senjiu generators:
1. Open the engine cover and remove the engine panel. You can see the cylinder lines. does a motor have? Yes, just a few more cylinder lines.
2. Pull out the steel wire directly by hand, but be sure to note that one cylinder wire corresponds to one spark plug, and remember the order of pulling the cylinder wires.
3. Use an extension socket to unscrew the spark plug.
4. Just install the new spark plug, but the spark plug gap is very large. If the gap is too small, it will burn easily. If the gap is large, the ignition will become. weak or even misfires. The general deviation is 0.7-0.9mm.
Morijiu generators are produced by Morijiu (Chongqing) Machinery Co., Ltd. The company was established on June 20, 2019, with a registered capital of 5 million yuan, and its legal representative is Li Kai. Its address is located at No. 21-22, Building 4, No. 5, Torch Avenue, Jiulongpo District. , Chongqing.
What is the reason why motorcycle spark plugs do not light?
Generally speaking, there is a approximate number of miles to replace regular spark plugs. candles are replaced approximately every 40,000 kilometers. Platinum spark plugs should be replaced every 80,000 to 100,000 kilometers. Simply track this mileage under normal vehicle use. There are many service manuals that recommend a replacement mileage shorter than this mileage. Regular spark plugs need to be replaced at 30,000 kilometers. You can extend the mileage appropriately because the performance ofThe spark plugs of most cars at 30,000 kilometers are still very good. This standard is normal When using a car, if the vehicle is used frequently or the load is too heavy, it should be replaced first.
The function of the spark plug is to ignite. When the engine cylinder reaches top dead center, gasoline can be burned to generate power through the ignition of the spark plug. Therefore, the stronger the ignition ability of the spark plug, the better. If the ignition ability of the spark plug is poor, the optimal ignition time will not be achieved, resulting in incomplete combustion of gasoline and the burned gasoline will not be fully used. do work. When the ignition ability of the spark plug decreases, the most intuitive feeling is that the car has low power, high fuel consumption and une large amount of carbon deposits. Replacing the spark plug is also a routine maintenance item and should be replaced regularly. . But a common situation is that we do not replace candles for a long time. Even if the mileage is reached and we think it is still usable, we will not replace it until a certain spark plug is broken. Some even replace which one. is broken. This is a bad way to maintain a car. ?
Common phenomena related to failure to replace spark plugs are engine jitter, unstable idling, ignition difficulty, increased fuel consumption and reduced power. If these phenomena occur, it is time to replace the spark plug again. Consider replacing the spark plug first. Remove the spark plug and observe the spark plug electrode to determine the combustion conditionof the cylinder. If the electrode is clean and brown, combustion conditions are good. If there is carbon deposit on the electrode and it appears black, it means that the combustion conditions of the cylinder are not good. In addition to replacing the spark plug, it is also necessary to check other faults. There is another criterion to judge whether to replace it. Look at the electrode spacing. If the gap becomes larger, it must be replaced. But first, you need to know the electrode gap size of the new spark plug. comparison, can you tell if it has become bigger.
If one of the spark plugs is broken, the phenomenon is that the engine shakes seriously and acceleration is visibly weak. Since one cylinder is missing, operation will naturally be unstable and power will decrease. If you have a computer tester, you can easilydetect which cylinder is not working. If you don't have a computer tester, you can remove the wires from the cylinder one by one to test. After removing the line from a certain cylinder, if the shaking becomes more serious, it means that the spark plug of that cylinder is not broken. If the intensity of the vibration does not change, it means that the spark plug of this cylinder is broken. If the spark plug breaks before reaching replacement mileage, a single broken plug can usually be replaced. If it is close to replacement mileage, it is recommended to replace them all. For example, if spark plugs need to be replaced every 100,000 kilometers and one is broken at 80,000 kilometers, it is recommended to replace them all. If one is broken at 60,000 miles, you can only replace one. There is no specific mileage standard indicating whether all spark plugsThe ignitions must be replaced. If one is broken, another spark plug or two should be removed for inspection. If the combustion condition is good and the gap is not large, there is no need to do this. Replace them, so if all the spark plugs need to be replaced. Check before replacement.
The reason why the motorcycle spark plug does not light is:
Motorcycle generator flywheel The magnet loses its magnetism; the motorcycle spark plug voltage is unstable; the motorcycle's ignition wire is in poor contact with the generator; the spark plug itself has quality problems; High voltage box failure; magnetic coil failure; ignition switch lock failure; poor contact between ignition wire and generator flywheel loss of magnetism, etc.
Common types
According to the calorific value, there are cold type and hot type according to the electrode material, there are nickel alloy, silver alloy; and platinum alloy, etc. ; if it is more professional, the types of spark plugs are generally as follows:
1. Quasi-type spark plug: its insulating skirt is slightly retracted into the end face of the shell, and the side electrode is outside the end face of the shell, is the most widely used .
2. Protruding Edge Spark Plug: The insulating skirt is longer and protrudes beyond the end face of the shell. It has the advantages of great heat absorption and good antifouling ability, and can be directly cooled by the inlet air to reduce the temperature, so it is not easy to cause hot fire, it therefore has a wide range of thermal adaptability.
3. Aluminum candleElectrode type mage: Its electrode is very thin, characterized by strong sparks and good ignition ability. It can ensure quick and reliable engine starting during severe cold seasons. can meet a variety of purposes.
