Why does a diesel sound like that?

처리 내용

As already stated, the ignition source between gasoline/gas engines and diesel engines are different and this is the primary reason for the difference in sound. I will try to explain those differences so you you'll understand why the sound is there with one, rather than the other. NOTE 1: There is a diatribe here, but bear with me as I attempt to answer the question as I believe the OP is requesting. I need to explain the differences for one to understand why a diesel engine sounds like it does. Fuel: Diesel v. Gasoline (Petrol) - As a fuel, diesel has a higher density than does gasoline. It is about 12% denser than non-ethanol gasoline (with ethanol based gasoline, the density is even higher, depending on the mix). Diesel offers a higher volumetric energy density at 35.86 MJ/L (128,700 BTU/US gal) v. 32.18 MJ/L (115,500 BTU/US gal) for gasoline, some 11% higher, which should be considered when comparing the fuel efficiency by volume. Engine Mechanical Differences: Diesel v. Gasoline -
