This was at a 14.7 stoich A/F ratio. Left side auto paint waste solvent. Right side pump 87 octane. 8-hour burn. Both fuels produced the same amount of heat at the metal test plate. |
The right side does seem darker, indication a less complete burn..?:
Ideally HC+O2=H2O +C right?
So theres no getting away from carbon/soot.
Not Ideal combustion is what gives you CO and CO2 gas,reducing C..?
If It's unburned HCs; that's a different story.
Perhaps they stick and get the C to stick?
The mess seen on the upwind side of intake valves seems to bear out this sticky hypothesis.
