Answer 1

It’s a combination of two factors;

1) Diesels tend to operate at lower RPMs where you’re more likely to encounter fundamental vibrational frequencies of the vehicle. Thus, you’re more likely to feel the vibration as a pulsing effect, rather than as a buzzing that you get in higher-RPM engines.

2) Because of how diesel engines works, the combustion event is more violent and energetic, and as a result the vibrations caused by combustion will be stronger.
