Regular replacement can ensure more complete ignition, allowing the mixture to burn more completely, thus saving fuel if the mixture can be completely burned, engine operating efficiency; 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, the spark plug will easily produce excessive carbon deposits and be stained by oil due to its performance. degradation. The spark plug should be medium or cold to improve the quality of the spark plug.
What is the reason why motorcycle spark plugs do notnot ignite?
Generally speaking, there is an approximate number of miles to replace regular spark plugs. spark plugs are replaced approximately every 40,000 kilometers, platinum spark plugs need to be replaced every 80,000 - 100,000 kilometers. Simply follow this number of kilometers during normal use of the vehicle. 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 ignition performance of most cars' spark plugs at 30,000 kilometers is still very good. This standard states that under normal vehicle use, if the vehicle is used frequently or the load is too heavy, it must be replaced in advance.
The function of the buttonIgnition gy 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 a 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 don't replace spark plugs for a long time. Even if we think thatThey are still usable after reaching the mileage, we do not replace them until a certain spark plug is broken. Some even replace the broken one. 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,The combustion state of the cylinder can be judged by observing the spark plug electrode. 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 thea 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 easily detect 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 severe, it means that the spark plugmage of this 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 plugs need to 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 anys the spark plugs need to be replaced. Check before replacement.
Won't changing the spark plugs have any impact on the car?
Motorcycles Spark plugsNo The reasons for ignition are:
The magnet of the flywheel of the motorcycle generator loses its magnetism; the motorcycle spark plug voltage is unstable; motorcycle ignition wire is weak; contact with generator; quality of the spark plug itself; igniter failure; high voltage box failure; ignition switch lock failure; poor contact between the ignition wire and the generator flywheel magnet; , etc.
Common types
According to the calorific value, there are cold type and hot type according to the electrode material, there is alloy of nickel, a silver alloy; and platinum alloy, etc. ; if he is more professionalsional, 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. Electrode type spark plug: Its electrode is very thin, characterized by strong sparking and good ignition ability, which can guarantee the efficiency of the engine even in severe cold seasons.It starts quickly and reliably.e, has a wide thermal range and can meet a variety of uses.
Many car owners do not understand and do not pay much attention to spark plugs, so they will replace them over time or not replace them at all for a long time. So, won't changing the spark plugs have an impact on the car?
It has an impact. When the life of the spark plug reaches the end, its discharge gap will be too large, which will affect the ignition effect of the car, reduce the engine power and increase the fuel consumption of the car .
If it is more serious, the engine will vibrate at idle, vibrate when driving at low speed, poor acceleration, poor ignition when the car is cold, etc. At this time, the spark plug needs to be replaced because this kind of problem occurs. After the breakdown, this means that combustion is not good and that aA large amount of carbon deposits will form, causing the breakdown to worsen.
The replacement cycle of a car's spark plug depends on the material of the spark plug. If it is a regular nickel alloy spark plug, it should be replaced after the car has driven about 20,000 kilometers. If it is a platinum spark plug, it should be replaced around 40,000 kilometers. If the vehicle uses iridium spark plugs, they can be replaced every 60,000 to 80,000 miles. If the vehicle uses premium iridium-platinum alloy spark plugs, the mileage can reach 120,000 kilometers.
