Home » Engine. Engine knock is one of these noises you do not want to hear from your car engine because it can damage many parts inside of your engine. Luckily, engine knock is often quite easy to get rid of. In this article, we will talk about the most common causes of engine knock and how you can fix the issue. These are the most common reasons for engine knock. Here is a little bit more detailed list of the most common causes of a knocking car engine:. The most common reason why your engine is knocking during acceleration is you have the wrong fuel in your car or just fuel with a low octane rating.

Either you refilled the wrong gas type the last time you were at the gas station, or it was just the gas station that had bad fuel in their tank. If you get fuel with a low octane number in your fuel tank, premature combustion may occur. This will cause the engine to knock. If the issue occurred after you refilled fuel and if you filled the gas tank full, you could try using an octane booster to boost up the octane a little bit rather than replacing all fuel in the tank.

The next common cause of engine knock is a bad knock sensor. The knock sensor is made for exactly this purpose — to prevent engine knocks. The engine control always wants to have such an advanced ignition as possible for higher performance.

If you fill your tank with fuel with a low octane rating, the engine will require a more retarded ignition timing to run without engine knock. If this engine knock sensor has gone bad, it can send false signals to the engine control unit, which will cause engine knock. Too advanced ignition timing will cause the engine to start knocking or pinging. Because of this, a faulty ignition timing could, of course, cause an engine knock. Unfortunately, this does only apply if you have an older car with adjustable ignition timing on either the distributor or an adjustable cam or crankshaft position sensor.

Newer cars control the ignition timing completely electronically, so you will not find it possible to adjust the timing.

However, if you have an older car with adjustable ignition timing, you need an ignition timing light to check the timing. Try to retard the timing slightly to see if it helps with the engine detonation. It is recommended to follow the repair manual for the correct ignition timing, though. This heat can cause the air-fuel mixture to self-ignite before the spark plug sends its spark, which will cause the engine to start knocking.

It is not very common that wrong spark plugs are causing engine knock or detonation, but it could absolutely happen. Spark plugs provide the ignition spark for the ignition of the fuel-air mixture. However, there are many different types of spark plugs, and if you buy the wrong type of spark plug , your engine can start suffering from engine knocking.

In the first instance, the spark is too weak, while in the second instance, the spark plug may not produce a spark at all. Check your repair manual to find the right spark plugs for your car model and ensure that the right model is installed. If you hear it knock only when accelerating, it is most likely engine knock or pinging, but if you constantly hear the noise, it may be caused by something else. Learn more here: 5 Common Car Engine Noises. Engine knocking or pinging occurs when the air-fuel mixture is getting self-ignited before the spark plug is igniting it, because of high heat.

It can be caused by a wrong ignition timing, too low fuel octane, or a lean air-fuel mixture. When the engine is on its way up, the air-fuel mixture will self-ignite halfway up, and as you can imagine, this will cause an incredible pressure because the piston has half of the way to reach the top. This can also create incredible heat that can melt holes into your pistons or the cylinder head. This is why it is a good idea to fix your engine knock in time and better not drive around with it.

Now when you know the different things that could cause the engine knock, you probably also want to know how you can fix it. The first thing you must think of is when the knocking appeared.

If it happened after you refueled the car, you probably have bad fuel in the fuel tank. To fix this, you need either to replace the fuel or try using an octane booster. If you find any trouble codes related to it, it is definitely time to repair the wirings or replace the knock sensor. You also want to check the spark plugs to make sure you use the correct spark plug type for your specific car engine. Use your repair manual to find the right spark plugs. If you have an older car or if the car engine has adjustable ignition timing, you do absolutely want to check and adjust it.

Check your repair manual to find out if you have an adjustable timing or not. Let a repair shop do it if you are not familiar with adjusting timing because you also need some special tools for the procedure. Engine knock sounds like someone is sitting and hitting your engine block with a metal hammer when you are accelerating. If you hear a knocking noise only when accelerating, it is most likely engine knocking or pinging. The first step to stop engine knocking is to ensure you have fuel with the correct octane rating for your car model.

You can try to use an octane booster to make it less sensitive to detonations. It is not recommended to drive a car with a knocking engine. There is no fixed price to fix an engine knock. Often you only have to use octane boosters or refill the fuel tank with new fuel.
