Diesel rotary?
 

i tried doing a search first, and can't find anything relevant...

anyways, i was thinking, we're oil-burners already, why fight it?

it seems like you'd just put the diesel fuel injectors where the spark plugs were and eliminate the fuel injection area by the intake.

obviously it's not that simple, but does anyone know why this wouldn't work or wouldn't be a good idea? can we not achieve the high compression ratio needed with the epitrochoidal housing shape?
