How do you know if spark plug is broken?

The simplest malfunction in spark plugs sparking the fuel-air mixture compressed inside the cylinders in the engine increases fuel consumption while reducing its performance. It is possible to detect many malfunctions in the engine by looking at the spark plugs. Thanks to the information below, you can find out if your spark plug is defective and if so, why.

If the nail spacing is not ideal
If the gap in the spark plugs is not ideal, the fuel-air mixture will not ignite well, even if the spark plug is new. Accordingly, the explosion in the combustion chamber weakens and the power of the engine decreases. In this case, most of the fuel in the vehicle exits the exhaust before it burns and the fuel consumption of the car increases noticeably. When you buy a new spark plug, nail spacing should be checked with a synthetic and it should be adjusted according to factory data if it is out of order before installing it against any situation.

If there is a deposit of oil on it
If the spark plugs are removed and checked for oil deposits, it means that excess oil enters the combustion chamber in the engine and lubricates the electrodes. In such cases, the spark takes place well below the normal level as the spark plug is covered with oil. This increases fuel consumption and reduces performance. The solution is to overhaul the engine.

If an institution has been formed on it
If the spark plug insulator tip, electrodes, and body have dried up, this means that the carburetor and injection setting are defective. In such cases, the engine will have an ignition cutout and the engine will work hard in cold weather. To solve the problem, it is necessary to check the air filter, adjust the carburetor and injection.

If the electrodes are boiled
If the spark plug electrodes have boiled and foreign matter has gathered, it means an overload due to untimely ignition. This problem is caused by improper ignition and valve settings, faulty distributor and poor quality fuel. To solve the problem, the engine ignition and fuel trim should be checked and a new spark plug installed.

If the spark plug is cracked
A rare occurrence of spark plugs is the mechanical damage to the electrode as a result of dropping the spark plug. In such cases, the ignition is incomplete and the spark spreads to other places. Therefore, the defective spark plug needs to be replaced.

What is the task of the spark plug?
The task of the spark plug is to transmit the high voltage generated by the coil to the combustion chamber and ignite the condensed fuel-air mixture through the electric spark between the electrodes. The most important factor that makes the spark plug work well is the spark length.

When should the spark plug be replaced?
- If your vehicle consumes more than normal fuel,
- There is an ignition leak in your engine,
- There is a decrease in the performance of your engine.

When to check
- When you have your motor advance set,
- When you have an engine test,
- When you buy a used vehicle.
