Hi Andy and all,
I think we're hitting on something here. As I said earlier and Bob
verified high compression carb engines ran better in high humidity and at
night. Winter driving comes to mind but other factors affecting engine
performance seem to negate the cold air density factor. You mentioned
lower octane which sparked something (sic) in the back of my head, octane
being an anti knock compound that replaced tetraethyl lead. Water vapor
retards combustion slowing the flame front which reduces engine knock
same as octane and voile, you can use lower octane fuel with water
injection. I would think both increase engine efficiency for the same
reason, no sense having a wasteful explosion when slow vapor expansion is
what you want driving the piston.
Maybe someone may add the "steam factor" and further explain the two
stage steam locomotive and turbine used today in electric power plants.
I'll start you off with those same two words, vapor expansion.
