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 work differently. A gas engine uses gas, which is treated to be be easily combustable. Diesel has to be heated and presurized, so the heat+ pressure, and the 2 stroke engine make it sound different.
