Aint this funnnnnnnnnnnnnn Jim, But Im sure the non sparkies are sick of it lol
I need some "learnin" on one of your statements, namely:
YOU STATE: "A partial vacuum 20" of HG is harder to fire a spark through than compressed air and fuel at 140 psi"
I thought as the compression increases, it takes more voltage to arc jump current across the plugs gap??????????????????? Ive always considered the voltage necessary to cause current to arc jump across a gap is a function of the gap distance and the medium (fuel and compression) in which the current must arc and that as the compression increases (higher molecule density) the voltage must rise to a higher potential to arc current across the gap
Not sure what you mean by "harder"
Are you saying it takes LESS voltage to arc current across the plugs gap outside the tractor (at atmosphere) then it does inside the combustion chamber where the pressures say 100 PSI???????????????????
As pressure is reduced theres for sure less air molecules packed in between the plugs electrode and ground strap and as its increased theres more molecules packed in between.
In racing or pulling applications where compressions are extremely high, thats where they have to use the High Voltage coils that reach say 20,000 to 40,000 volts versus stock (way less compression) where the plugs may fire at 10,000 volts SUCH AGREES WITH WHAT I THOUGHT BUT IS OPPOSITE FROM WHAT YOU SEEM TO BE SAYING???
TALK TO ME JIM ??????? Chemistry was never my best subject ya gotta realize
