What happens if the spark plug gap is too big?
If the spark plug gap is too big, it can cause several issues with your engine's performance. The spark plug gap is the distance between the two electrodes on the spark plug, and it needs to be set to the manufacturer's recommended specification for optimal engine operation.
Consequences of an Excessively Wide Spark Plug Gap
When the spark plug gap is too wide, it can lead to the following problems:
- Misfiring: A wider gap makes it harder for the spark to jump across the electrodes, resulting in misfiring and incomplete combustion in the engine cylinder. This can cause rough idling, hesitation, and loss of power.
- Increased Fuel Consumption: Misfiring and incomplete combustion lead to unburnt fuel being expelled through the exhaust, reducing the engine's efficiency and increasing fuel consumption.
- Damage to Ignition System: The larger gap requires a higher voltage to create the spark, which can put additional strain on the ignition coil and other ignition system components, potentially leading to premature failure.
- Reduced Engine Performance: The combination of misfiring, incomplete combustion, and increased fuel consumption results in a noticeable decrease in engine power and acceleration.
It's important to note that the recommended spark plug gap can vary depending on the engine and the type of spark plug being used. Consult your vehicle's owner's manual or a professional mechanic to determine the correct gap for your specific application.
Adjusting the Spark Plug Gap
If you suspect that the spark plug gap is too wide, you can use a spark plug gap tool to measure and adjust it to the manufacturer's specification. This typically involves gently bending the ground electrode to decrease the gap. It's crucial to be careful when adjusting the gap to avoid damaging the spark plug or the electrode.
Regularly checking and maintaining the proper spark plug gap is an important part of engine maintenance, as it helps ensure optimal engine performance, fuel efficiency, and longevity.
