Why doesn’t someone make a rotary engine that can run on diesel? It burns at a lower temp which is a major factor to rotary’s heat problem; also it could increase the fuel economy and could still have it turbo charged ported all the same stuff that we do now for more power.

I know it would require a lot more than just putting diesel in it and glow plugs, but really there could be be power and reliability with the combination of them.
If i was an engineer I would build it.
Has anyone thought of this before, if not some do it please.

I am just thinking out side the box.

 

Stop hovering let me know what u think!!!!!!!!!!!

 

It is more complex than what one would think. The combustion process within a diesel engine generates a substantial amount of heat as well as a great deal of pressure. The diesel cycle in particular-if you look at the P-V diagrams- can generate combustion pressures that would dwarf the otto cycle pressures. This excessive amount of pressure generates tremendous heat-observing air only as the working fluid, we are talking 7000+ degree F cylinder temperatures with midrange compression ratio of around 15.5:1 or so.

I do not think that a diesel engine would be reliable unless budgets were not an issue, the ability to create new irons specific for this purpose, higher compression ratio rotors, etc. etc.

 

its been done. in fact there is a company marketing a diesel rotary in the US.

 

Do you have a link, would love to see how they did it.
