Why do diesel engines rattle?

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.

What causes noisy fuel injectors?

As with misfiring, this is normally down to the injector nozzles being clogged with particles, which interfere with the atomisation and spray of the fuel.
