An important part of the motorcycle is the spark plug, which looks small but does a great job. This small device is attached to the engine. Its main function is to create a spark inside the engine. Because of this, petrol, octane, or fuel is burned inside the engine.
Spark plugs are a crucial component of the engine’s ignition system. They work by providing an electric spark to ignite the air-fuel mixture within the engine’s combustion chamber.
Let’s see how it works
Voltage Generation
Motorcycle ignition coils generate a high voltage, usually between 12,000 and 45,000 volts.
Spark Creation
This high voltage travels through the spark plug wire to the spark plug. The plug has two electrodes: a center electrode and a ground electrode. An electric arc, due to high voltage, jumps the gap between these electrodes, creating a spark.
Ignition of the Air-Fuel Mixture
When the piston is at the top of its compression stroke, the spark ignites the compressed air-fuel mixture.
Combustion
The ignition of the air-fuel mixture creates an explosion, forcing the piston down. This drives the motorcycle’s crankshaft and produces power.Regular maintenance of spark plugs is essential for efficient engine performance. This includes checking the gap between the electrodes and cleaning or replacing the plug as needed. Proper functioning of the spark plug ensures optimal fuel combustion, good fuel efficiency, and smooth engine operation.
How to Clean Spark Plugs
One of the main reasons for motorcycle engine starting problems can be attributed to spark plug issues. Spark plugs need to be cleaned regularly to ensure optimal performance.
If there is a problem with the motorcycle’s spark plug, the engine may not start properly. To troubleshoot this, follow these steps:
- Check the fuel.
- Ensure fuel is visible in the fuel line.
- Smell the fuel to check if it resembles kerosene.
- Always ensure that no water mixes with the fuel.
- Clean the spark plug.
- Make sure the key is turned on.
- Start the engine quickly by pressing the choke.
- Check the air filter.
- After checking everything properly, the engine should start.
Spark Plug Cleaning Requirements:
If your motorcycle engine does not start properly despite having sufficient fuel, the spark plug might be the problem.If your motorcycle engine has diluted or contaminated oil, it will not burn the fuel properly.
As a result, waste oil and carbon may collect on the spark plug, causing the engine to stop suddenly. Therefore, regular cleaning of spark plugs is necessary. You can have a spark plug and engine oil mechanic clean them, or you can do it yourself.
Here’s what you need to clean the spark plugs yourself:
- Spark Plug Socket Wrench (found in a motorcycle toolbox)
- Brush made of metal wire
- Clean cloth
- Air blower (optional)
- Sandpaper
How to Remove the Spark Plug ?
Usually, the spark plug is located on top of the engine. It is often connected with a black wire cap. If the engine is hot, allow it some time to cool down. Clean the dust around the plug before opening it to prevent dirt from entering the engine.
How to Clean Motorcycle Spark Plug Dirt:
- Using your hand, carefully twist the cap of the plug and open it.
- Use the spark plug wrench from your toolbox to twist the spark plug counterclockwise to loosen it.
- Once loosened, you can remove the spark plug from the engine compartment using your fingers.
The spark plug will look like the picture used.
Always keep tin foil in your toolbox. Clean the spark plug thoroughly and carefully with tin foil. Use a brush regularly if necessary, but ensure that the spark gap remains the same. Finally, use an air blower to remove any dust.
Place your cleaned spark plug back into the engine with your fingers and twist it into place. Tighten the plug with a socket wrench. After completing all these steps, replace the plug cap properly and start your engine. You should notice your bike starts with a spark.
If you follow the above steps carefully, you can clean your motorcycle’s spark plug, and the engine will start smoothly. Regular spark plug cleaning is essential for maintaining your motorcycle’s engine and ensuring optimal riding performance.
