Why do gas and diesel engines sound different? From my understanding they’re both internal combustion engines but they have different ways of igniting. Is the ignition process why it sounds different or is it a more mechanical reason? I.e. more moving parts or mufflers etc.
Im talking about normal stock gas and diesel engines. No whistlers, aftermarket cams or exhaust.

Diesel engines tend to have much higher compression because the fuel is less prone to detonation, compression has a very large effect on the sound an engine makes.
