What causes a noisy diesel engine?

Diesel engines make a lot of noise while burning the fuel. The main reason behind this is that diesel molecules are much bigger than petrol molecules and the engines run on high compression. … The heat which is generated during compression leads to self ignition of the fuel. Thus, clattering noises are produced.

Why do diesels sound like they are knocking?

Answer: The clatter results from the combustion of diesel fuel inside the engine. In a diesel, the fuel is ignited by high pressure and temperature inside the cylinder, rather than by a spark plug. The clatter is the result of fuel not burning as evenly as in a gasoline engine, creating a knock.
