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?

Royce

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?
Royce

There has been advertising of a diesel rotary (two rotors, 80hp) in germany
from wankel rotary. Look at http://www.wankel-rotary.com/seite1_e.htm, they
speak of a project of a family of diesel rotaries.

They are no longer available.
