This subject needs expert analysis. I just cannot believe that the air
pump results in an after burn as this would mean very hot exhaust pipes and
presumably a noticeable belching out of flames. A simple test to see if
there was any oxygen left in the exhaust of a non-air pumped car would be a
start. This would mean the air pump was not doing anything more than
adding more air and thus being useless! Anyone got the means to test
exhaust gases? The spontaneous burn-off seems unlikely as there is no
ignition and no compression. If there is unburnt fuel just looking to go
whosh then what happens when you put a match to the exhaust of a non-pumped
car. Do you get a burn??? Seems that if you do, putting a spark plug on
your tail pipe may be fun....Mummy, look at that car go.....
