All this is nonsense you must realize.  Diesels make fine automobile and smaller truck and equipment powerplants that can attain amazing fuel economy numbers.  Diesels can be smooth, quiet, and fun to drive since by design, they have very driver- friendly torque output.

It took automotive engineers many iterations and many years of R&D to come up with the system we take for granted today.
