What Is Diesel Knock?
Before you learn how to prevent diesel knock, you need to know what it is. Diesel knock occurs when a large amount of fuel accumulates in the combustion chamber. When this happens, the high pressure from the fuel in the combustion chamber causes diesel knock, which is a clanking or knocking sound that emits from your engine.

Maintain Your Engine

You’ll need to learn how to pick the right diesel engine parts for your semi and replace them when they become damaged or worn.

Stop at Reputable Gas Stations
One of the top causes of diesel knock is low octane gasoline, also called “bad” gasoline. Luckily, avoiding it is easy. All you need to do is ensure that you stop at reputable gas stations. These gas stations should sell gasoline that contains the right amount of octane, thus preventing diesel knock and allowing you to continue your trip.

Never Ignore Diesel Knock
Too often, drivers will ignore the signs of diesel knock and try to drive their semi. But this sound is not normal, and it can damage your semi’s engine irreversibly in severe cases. If you notice that your vehicle has diesel knock, you should pull over. Don’t continue to drive until you’ve resolved the issue. The more you drive with this problem, the more you damage your engine and incur costly repairs.
