We all know that spark plugs are a major component in the ignition system of automobile engines. Spark plugs are found on all gasoline engines. The role of the spark plug is to introduce high-voltage electricity generated by the ignition coil into the engine cylinder, and generate a spark between the gap between the spark plug electrodes to ignite the mixture. Xiaoming should replace the spark plug according to the number of kilometers. Generally speaking, the life of an ordinary spark plug is 20,000 kilometers.
Use your spare time on weekends to replace spark plugs for Octavia with spark plug replacement tools.
First remove the guard plate with a ring wrench.
Four screws can be easily removed to remove the guard.
See four ignition coils.
Remove and replace in the order starting from the right.
It is still very skillful to remove the ignition coil. Don’t remove it violently, but be gentle.
The spark plug can be seen after the ignition coil is removed.
Then use the sleeve to remove the spark plug.
This is the removed spark plug. You can see that the spark plug is still burning very well and golden.
Comparing the old and new spark plugs, we can find that the gap between the electrodes of the replaced spark plug is a bit large.
Then use a tool to install a new spark plug.
Continue to replace the second spark plug in sequence.
In fact, whether the spark plug needs to be replaced, you can remove it and check it to see if the color of the burn, the gap between the electrodes, and whether there is any leakage in the gap between the porcelain body and the metal shell.
If the spark plug is used for too long, and the clearance is too large, the ignition energy will be reduced. The car will speed up and slow down, resulting in a significant increase in gasoline consumption.
Frequent inspection and replacement of new spark plugs can ensure the safety of the car.
Replacing new spark plugs will also help save gasoline consumption.
The four spark plugs were replaced one by one.
The last thing is to install the guard plate.
The four screws that secure the guard plate are completed.
Start the engine and check the lighting effect. It is very sensitive, and the fuel consumption is reduced a lot in an instant.
In fact, it is generally difficult to start a car in the cold state in winter. After replacing the spark plug, it can obviously eliminate the obvious feeling of frustration and idle jitter when driving, and improve engine acceleration performance.
