What to do if a spark plug is flooded? What happens when a spark plug is flooded?

Fault diagnosis and troubleshooting methods:

Remove the spark plug and observe carefully, whether the calorific value of the spark plug is the same as the calorific value of the spark plug of the original car, and the spark plug with higher calorific value has poor oil resistance.

If the calorific value is the same, observe whether the oil stain on the spark plug is caused by the carburetor, and if so, check whether the carburetor mixture adjustment is appropriate and whether the oil level is too high.

If the spark plug is drowned due to the wear of the engine piston ring or the valve guide rod causing the oil to enter the combustion chamber and drown the spark plug, the temporary emergency measure can adjust the gap between the spark plug electrodes to be larger, and the most fundamental measure is to overhaul the engine.

The spark plug is flooded, that is, the spark plug is soaked in gasoline and does not jump the fire, the car mechanic said that the oil is big, and so on will be the gasoline volatilization is almost the case, the ignition can be on the car, although the problem is solved, the other situation is: the car condition is not good, the cool car can not be on the car three times or five times, refueling, more oil, there is more carbon deposition in the spark plug, affecting the ability of the jumping fire is possible, in this case, the solution is to break off the spark plug, completely remove the spark plug of various impurities and carbon deposits.

1. Replace the spark plug with a new one

When the spark plug is flooded, we first need to determine whether it is caused by the aging of the spark plug. If the ignition ability of the spark plug is weakened due to the natural aging of the spark plug, then the engine will not be able to ignite the gasoline injected into the cylinder, which will cause a vicious cycle of flooding, and if this is the case, we can solve this problem by simply replacing the spark plug with a new one.

2. Replace the fuel injector

If there is no problem with the spark plug, then it is likely that the pressure of the fuel is too high, or that there is an oil leak at the fuel injector. If the fuel pressure is too high, you can use a fuel pressure gauge to measure the oil pressure in the fuel system, or use a dedicated computer to read the fuel pressure data to see if it is within the normal range.

If it is the problem of oil leakage from the fuel injector, you can remove the fuel injector to see if there is a problem of oil dripping, if the fuel injector is dripping, we can solve it by replacing it with a new fuel injector.

3. Recalibrate the time

If none of the above reasons are the above, there is another reason, which is that there is a problem with the engine valve timing. When there is a failure in the ignition timing, the oil-gas mixture will not reach the normal proportion, and there will be more oil and less gas, or less gas and more oil. When we detect, we can remove the timing front cover, and then re-calibrate, and this problem can be solved after the proofreading is correct.

No oil supply at start-up.

If the atomization of gasoline is not good, it will lead to insufficient combustion, resulting in the spark plug being stained with oil, forming the phenomenon that the spark plug does not jump the fire, or the ignition is weak. The next time you start the car, don't step on the accelerator to refuel and test.

If your car is often difficult to start the car, or there is often a phenomenon of flooding the spark plug, you must go to a professional maintenance center to overhaul it.

If the ignition capacity of the spark plug is okay, then the spark plug can be disassembled, and the fuel attached to the surface of the spark plug can be ignited with a lighter, the purpose is to dry the fuel, and then it can continue to be used normally, if the engine can no longer be started after being flooded, then the spark plug needs to be replaced.

If the spark plug is flooded, it may cause a lack of fire in a cylinder, and the lack of fire will cause the engine to shake, but it should be noted that the engine shake is not necessarily caused by the spark plug being flooded, but also due to the aging of the spark plug. After the spark plug is flooded, there is a high probability that it will not be restored overnight, because the spark plug is flooded to a large extent not suddenly, but caused by accumulation.

Solution:

Drowning of a spark plug usually means that there is a large amount of black oil between the electrodes of the spark plug and it is submerged, which will cause the current to leak and not flash. Drowning of a spark plug is usually caused by the high calorific value of the spark plug, poor oil resistance, improper adjustment of the carburetor that makes the mixture too concentrated, and the wear of the valve guide rod or piston ring of the cylinder causes the oil to escape into the combustion chamber.

The spark plug is flooded is that the gasoline atomization is not good, and the insufficient combustion leads to the oil sticking to the spark plug, which can not be ignited or is very weak, which is generally caused by the accelerator pedal being too large when it is just ignited, and it is best not to step on the accelerator when starting in the future, as long as the car is on the road.

The measures that can be taken if it is flooded are: 1. If the spark plug has a strong ignition ability after being flooded, the owner can take out the spark plug, use a dryer to dry it and then load it into the vehicle to continue to use; 2. If the spark plug cannot be ignited, it is recommended that the owner replace it in time and cannot continue to use it. In the daily use of the vehicle, if the spark plug is submerged, the main reasons are:

1. In the process of burning the oil, the concentration of lead and steam is too high, which causes the position of the oil page to rise and causes the blockage of the air filter, which then causes the damper to fall and the spark plug to be submerged; 2. When the spark plug is used, there is often a phenomenon of partial fire and leakage, and the ignition of the igniter inside the vehicle is abnormal, resulting in the spark plug being submerged; 3. The failure of the mechanical part will also cause the spark plug to be submerged.

The spark plug is the eye and rain gauge of the gasoline engine, and many problems will be reflected in the spark plug. The spark plug is flooded, and it seems that the spark plug does not ignite, causing the gasoline to enter more and accumulate on the electrode, but in fact, there are many reasons.

First, the concentrated steam is too thick, the oil level is too high or the air filter is blocked, and the damper falls ......Isocarburetor ** is not normal.

Second, the spark plug is ignited, leakage, the ignition is abnormal, the high-voltage package is abnormal, the fire is weak, and the charging coil and trigger coil in the magneto are faulty, and even the ignition switch (key) has a short circuit and leakage.

Third, the failure of the mechanical part, ignition misalignment, gas distribution misalignment, abnormal valve clearance, etc. will also lead. After the spark plug is very flooded, see how the ignition is, if the ignition is still strong, bake and dry, drain the oil in the exhaust cylinder and try again. If the spark plug is no longer ignited, if you want to replace the spark plug, you have to find out **from the disease**.
