Your car is more than just another possession. It represents your freedom and ability to go where you please. Your automobile is also an integral part of your career and family life, providing a safe way to take care of your responsibilities. So, when your car starts to make odd noises, it is wise to pay attention to what it is trying to tell you. A knocking sound in your engine is a good example of when to take notice.
What Makes Your Engine Knock?
If you hear a knocking sound coming from your engine, it could be a sign of numerous problems. They range in severity from the simple fix to serious automotive damage.
The "knock" usually occurs when there is an improper mixture of air and fuel. This causes the fuel in your car to burn unevenly in pockets instead of uniformly. Unless it is taken care of in a timely manner by a qualified professional, it can cause damage to the cylinder wall and piston.
The knocking sound could also indicate inadequate lubrication in the head area's upper cylinder. When the valves and lifters lack the proper amount of oil, they can create a ticking sound when they move.
There are three main causes for knocking sound in your engine from fuel and ignition system issues.
Your Fuel Octane Is Too Low
The fuel octane level measures its ability to prolong the detonation of an engine's air-fuel mixture. It is this combustion that creates the knocking noise you hear.
The Fuel Is Burning Inefficiently Due to Carbon Deposits
By law, the fuel your automobile uses contains a carbon cleaning detergent. However, this does not prevent carbon from forming. This carbon forms on spark plugs, valves, and other engine components.
Your Auto Has the Wrong Spark Plugs or Spark Plug Gap
Using any spark plugs other than those the manufacturer recommended, you risk having a knocking engine. Also, if your spark plug gap is too close, your spark will be too weak. A gap too broad could keep it from sparking or cause a misfire.
