When you accelerate or decelerate your car, you may sometimes hear a knocking sound. This knocking sound is usually caused by the engine, and it can be a sign that something is wrong.

There are a few different things that can cause the engine to knock. One common cause is a problem with the engine’s compression. When the engine’s compression is off, it can cause the fuel and air to mix unevenly, which can lead to knocking.

Another common cause of knocking is a problem with the engine’s timing. When the engine’s timing is off, it can cause the fuel and air to mix unevenly, which can lead to knocking.

If you are hearing a knocking sound when you accelerate or decelerate your car, it is important to take it to a mechanic to have it checked out. Ignoring the problem could lead to more serious damage to the engine.
