I don't understand this. If you inject fuel into the exhaust, yer cooling 
the exhaust gases, but there's a good chance that the fuel will ignite and 
since it's when the exhaust valve opens, the timing of this will be totally 
off and put pressure on the piston to stay down, not come back up as it 
should. Also that fuel is just wasted b/c it's not really used for gaining 
power or torque, just for cooling. Can someone explain this?
