Diesel engines have no spark plugs (and no ignition system). Gasoline engines have spark plugs (and ignition systems).

So besides installing ignition system, you would have to find a way to install spark plugs. Installing a ignition system would be somewhat easy compared to installing spark plugs.

Good Luck.

Answer 2

Why the heck would you do that? Just burn veggy oil like you're supposed to in a diesel.

Answer 3

Its way too much of a problem. you have no ignition system and too high of a compression ratio to run cng in a diesel.
