Why do diesels clatter?

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. via
