Now that I think about it I think he said he did the calculation to see what it was, I think he said he figured out combustion temp, rpm's and a few other things to figure out the air/fuel ratio??? Another part of why I believe my experiment should work is I was building a house for a guy and it had no power on the job. So he brought his 12Kw diesel generator for use to use. One day when he came to do trim he filled it with gasoline accidentally and once the fuel got the the injectors that thing started screaming. It had a max rpm of 15,000 and he never had it scream like that! After shouting off the fuel(it was also at idle the whole time!!) it took about 30-45 minutes for it to stop. So then I got to thinking, if a diesel running of gasoline, at idle, can hit that high a rpm's then how much less fuel would get it to idle???
