What Does it Mean When an Engine Knocks? 

If you’re unfamiliar with the term, you’re probably wondering what it means when an engine “knocks”. Also called “pinging”, an engine occurs when the air-fuel mixture is incorrect, causing uneven burn pockets rather than uniform bursts. 

When driving the 2019 Alfa Romeo Giulia and using regular gasoline, hearing a slight knock once in a while is no cause for concern. However, if you hear a continuous hard knock, then there could be an issue. Consider switching gasoline types or taking it in for a service.
