Why does it burn spark plugs?
This can be due to multiple reasons, such as using the wrong spark plug, a bad gap or a very low octane number. In these cases it is recommended to use spark plugs with a higher thermal degree and logically, take the car to the mechanical workshop.
How do you know if a spark plug burns?
These same are some clues that the spark plugs may not be working properly:
- Tourism jerks when driving.
- It has a rough idle.
- Difficulty when starting.
- Increased fuel consumption.
- Power loss.
What does a charred spark plug mean?
Carbonization problems. They can be caused by the presence of soft or black deposits, which may indicate that the fuel has too much air, the ignition is very weak or the spark plugs have a bad heat specification (they are too cold).
What causes soot on spark plugs?
Soot deposits: the spark plug has a black or roasted color with carbon deposits, in addition to perceiving driving symptoms such as jerks, difficulty starting or failures within the ignition.
What happens as soon as a wagon burns a candle?
Due to the fact that coal is a conductor of electrical energy, when it is charred it will suffer a loss of insulation, causing ignition failures. As rotation increases and you are loading the engine, the temperature at the tip of the spark plug rises.
What to do when the spark plug comes out black?
If the spark plugs have a black and oily cast, it could indicate an error within the oil system. This indicates that there is great wear on the engine. Recommendations: Inspect your vehicle for signs of wear on the valve heads, descender seals, and piston rings.
How to diagnose by spark plugs?
Certain signs of bad spark plugs are poor acceleration, high fuel economy, or rough idling. Abnormal operation inside the engine and loss of power. If the spark plugs or their own connections do not work properly, the engine will not be able to start.
What does it mean when the spark plug is black?
Black spark plug: there is a bad combustion and an excess of soot is produced at the tip of the spark plug, the area where the spark is generated. Here there may be a dilemma in the richness of the mixture (more fuel is injected than necessary).
How to decarbonize a spark plug?
Clean the very upper part of the spark plugs (where the electrodes are) with 90ºC alcohol. Blast them with air under pressure to remove debris from their surface. Help yourself with a wire brush and a cotton rag to clean the threads well. Dry thoroughly and reapply.
What happens as soon as a spark plug is blown?
Worn spark plugs cause the air and fuel mixture to not burn correctly, which increases consumption. Power loss. Failing to start the car can cause a reduction in engine power as well as an increase in the gases emitted by the exhaust pipe.
