If the spark plug has not been changed or cleaned for too long, it can cause the following problems:
Reduced Fuel Economy: Aged or worn spark plugs can cause inadequate or misfired ignition, which affects fuel economy. If you notice that your car's gas consumption has increased, it's most likely a problem with your spark plugs.
Difficulty starting the engine: If the electrodes of the spark plug wear too much, the gap between the electrodes will increase, making ignition more difficult. This can cause the engine to start slowly, fail to start, or stall immediately after starting.
Reduced power: If the spark plugs are not replaced or cleaned in time, it may cause insufficient ignition, which reduces the power and torque output of the engine.
Pollution of the environment: The unburned oil-air mixture of the spark plug will be discharged into the atmosphere, causing pollution to the environment.
Therefore, it is very important to check and replace the spark plugs regularly. It is generally recommended to replace it according to the maintenance manual of the car manufacturer or the annual mileage.
Use mismatched spark plugs.
The spark plugs of each car model are specially designed with specific specifications and parameters, including electrode shape, calorific value, size, etc., which are related to the working principle and design of the engine. Using mismatched spark plugs can cause the following problems:
Decreased ignition performance: Unmatched spark plugs may not be able to provide the correct ignition energy and correct spark shape, which may lead to decreased ignition performance, thereby affecting the working efficiency of the engine.
Engine failure: If the wrong spark plug is used, it may cause engine failure, such as knocking, shaking, and engine failure.
Poor Fuel Economy: Using mismatched spark plugs can result in poor fuel economy because the spark plugs do not provide the correct combustion energy, resulting in insufficient fuel burn.
Therefore, it is recommended to use spark plugs with specifications and parameters that match the model when replacing the spark plugs to ensure the normal operation and performance of the engine.
