Re: [DML] Re: Engine Options - fuel options

Tom,

Why do you think that the higher octane of CNG will cause you to loose 
power.  My understanding of octane rating is that it slow down the 
burning process.   This is more important in high compression engines, 
because the higher compression make the mixture burn faster.    In a 
low compression engine this should not make any difference.

Higher octane will allow you to advance the timing so that you may 
actually be able to increase your peak pressure.

I am also curious as to why you say it will be hard to start?   Methane 
has a very low vaporization temperature. It should turn to vapor even 
in the coldest weather.

CNG conversion/ dual fuel systems were available on Ford and other SUVs 
in the South west US to be able to take advantage of a special $5000 
tax credit.     People never used the dual fuel capability, but  got 
the tax credit.  Perhaps some of this equipment would be useful.
