Reality speaking, your vehicle’s engine is not supposed to make any other (disturbing) noise than they are supposed to. This is why if you hear a noise out of the general ambit, you should start worrying.
When you hear strange noises coming from your engine, it means that there’s something wrong. And it requires your attention as early as possible.
In this blog, we will share with you some of the [probably] most engine noise issues that you should not disregard.
What Is The Engine Noise?
The engine noise can be defined as the sound made by an internal combustion engine when it works. It includes all those sounds that come from the engine itself and its components such as pistons, valves, etc.
The engine noise can also include the noise made by the exhaust system, which consists of the pipes that carry away the gases produced by the engine.
Why Does My Car Make Strange Sounds?
If you have heard these kinds of noises before, then you might think that it’s normal for your vehicle to make them. But actually, this is not always the case. There are many reasons why your car may make noises.
Some of these noises are very common and easy to fix while others require more advanced solutions. Sometimes, the problem is so serious that it cannot be fixed at all.
Here are some of the main causes of engine noises:
1. Clunking or Knocking
This is one of the most common engine noises. It occurs when the piston rings rub against each other during their movement. As a result, the metal-to-metal contact makes a loud clanking sound.
2. Rattling
Rattling happens when the engine vibrates in a way that creates a high frequency. This kind of noise usually comes from loose parts inside the engine.
3. Coughing
Coughing is caused by the valve springs rubbing against the camshaft. When the engine runs, the camshaft rotates causing the valve springs to move up and down. This motion generates a high vibration. This vibration is transmitted through the chassis and the body of the vehicle.
3. Pinging
Pinging is another kind of engine noise that is usually associated with the intake manifold. If the air filter becomes dirty, it could cause pinging.
4. Backfiring
Backfiring happens when the fuel ignites prematurely inside the cylinder. This results in a loud bang.
5. Screeching
Screeching is a type of engine noise that is similar to backfiring. However, it is different because it comes from the exhaust system.
6. Hissing
Hissing is a low-frequency noise that is often associated with the exhaust system. It is caused by the hot exhaust gas passing through the muffler.
7. Vibrating
Vibrating is a low-frequency noise caused by the crankshaft. It is a very annoying noise, but it is not dangerous.
8. Shuddering
Shuddering is a low-pitched noise that is mostly associated with the transmission. It is caused by vibrations from the drivetrain.
9. Crackling
Crackling is a low-frequency crackling noise that is often associated with the ignition coil. It is caused by electrical arcing between the spark plug wires and the terminals.
10. Grinding
Grinding is a high-frequency noise that is usually associated with the timing belt. It can be caused by loose parts on the belt.
In Conclusion
These are just a few examples of what could happen when your car makes weird noises. They can be caused by several things, but in most cases, they’re due to one thing: the engine oil.
If there is too much friction between the moving parts, the engine will start making strange sounds. These noises are called “engine noises” because they occur only when the engine is running. When you hear an unusual noise coming from your engine, don’t panic! You probably won’t need to replace any major components. Instead, try to identify the source of the noise first before calling a mechanic.
You should also check if the engine has been properly maintained. If the engine was recently serviced, make sure that you have all the necessary parts. If you do find out that the problem lies within the engine itself, then call a professional mechanic immediately.
