Yup. Diesel and hybrid are the proverbial horse and carriage.
Many years ago I had an idea for a variable combustion chamber: One that would alter the compression ratio to match any type of fuel with the engine and/or conditions.
After some brief research on the uspto dot gov, I saw other designs that would do the job, though in a different way.
Years later, I still haven't seen any of these on the market.
