- [What Causes Engine Knocking When Accelerating?](https://www.engineeringchoice.org/engine-knocking-when-accelerating/): Do you hear some metal clucking sounds from the engine while accelerating? It’s nothing to be worried about, as it is a common experience for most drivers, called engine knocking (detonation). Engine knocking occurs when some of the fuel in the cylinder detonates before the other fuel. Under normal circumstances, the spark plug initiates the fire, and all the fuel in the cylinder burns, the explosion of which is kept in control. The spontaneous ignition of fuel and air in the cylinders is the key to engine knocking. In this article, we shall discuss in detail engine knocking while accelerating. We ... Read more
