We have looked at several sites that mention heavy fuel rotary's.

(diesel,

kerosene, jet A, JP4, JP5 etc) but none so far have had any detailes.
We have been thinking about a diesel rotary, but not compression

ignition, spark

ignition instead.

Some reasons for this is heavy fuel is oily, so the apex seals should be

able to

get their lube from the fuel itself. I think it was an article on OMC

that stated

they had problems getting the engine started.
Does anyone know the specific heat in diesel (heavy fuel) as compared to

gasoline?

All of these alternate fuel have a lower heating value per pound than
gasoline
but some of them have higher density making then more competitive on the per
gallon basis - some examples per an old reference of mine -

fuel             high heating value btu/lb
gasoline            20,230
kerosine            19,980
fuel  oils           18,630
methyl alcohol     9,063
ethyl alcohol     12,835
by the way - Hydrogen is about 40,000per lb, but about 150 per cubic ft

Thanks Vance, has anyone worked on a diesel rotary, that is a company developing
anything in this regard?
