Hi all. If this is an April 1st joke, well done. It "woke up" the list.
If not, a word of warning. Reducing the fuel available during combustion 
does not put the flame out as some one suggested. The flame looks for 
something else to consume. In an IC engine, aluminium may become the fuel. 
This has been documented many times. Phil Irving makes several references to 
holed pistons in his book "Tuning For Speed". Its a bit dated now, but the 
physics are still the same.

The same process is used for oxy-acetylene cutting. Turn up the oxygen and 
burn steel.

Take care on lean burn.
