[Diy_efi] EFI and heavy fuel (eg. Parafin )

[Ron Schroeder]

Hi Thonas,

Just out of curiosity, how low in compression ratio do you need to go to run
a spark ignition engine on kerosene?  Can those engines also run on diesel
fuel or is that just too heavy?

Thanks,

Ron Schroeder

Hi!

I'll say what I know about kerosene engines:
I don't know if you'll be able to start from a winter cold engine. I have an
old farm tractor who works with kerosene (carb'ed of course, it's an IH
Farmall A), but for starting, it has a small gasoline tank and a switch
valve, so you start with gasoline then switch over to kerosene. The singular
part is that the intake manifold is highly heated to promote the kerosene
vaporization. The heating is provided from the exhaust manifold... well,
there is really one manifold, because the intake and exhaust manifolds are
one! You can realise the kind of heating kerosene needs.
I guess that injected the need for heating will be less, but still a
significant factor.
Hope this engine description is useful.

Tomas
