Carbeurated diesel
#11
URIKA i figured it out.
first of IM WRONG carborated or throttle bodied diesel wouldnt work
second thanks for getting the gears to turn guys.
this is gonna be kinda long but im pretty sure i figured out why it wont work.
first problem- if it were carborated at an idle it would be scavaging like crazy (flooding itself if it were gas) but because it a diesel it would still be chugging away blowing LOTS of black smoke. when the throttle is then cracked it would go nuts because it would have so much unburned fuel in the intake manifold and now excess air to light the fire. thus a runnaway.
second problem- if said diesel fuel explodes at say 14 to 1 compression and you have a 20 to 1 engine. ( numbers flying out of the old ars here) then the abundance of fuel would ignite before the piston had reached DTC and would VIOLENTLY knock. if it could even overcome the blast which i kinda doubt.
a throttle body could solve the runaway problem but WOULD NOT solve the pre ignition catastrophy. a throttle body WOULD work IF the compression ratio was lowered to the exact number in which diesel ignites, but what would be the point and changes in altitude and temp ect would affect this greatly.
i think???

if peak compression was lowered to ignition of diesel fuel theoreticly this might idle but load up still or flood, BUT it would be almost impossible to start. plus any wear on the engine would make it useless , but like you said any change in altitude, temp would make this thing one cranky pos. it would have to be exact right temp, humidity, altitude, air density etc for it to work.

Plus I don't think your just going to find any old gas intake and have it match the ports of a 7.3. You would have to cross referance a gas motor tha has a pretty close deck height. And even then the ports don't have to be dead nuts but should be close. The chances of that are slim and none!
