[QUOTE="Nesikep, post: 1146156, member: 9096"] Yep... you have Carbon and Hydrogen (mostly) in the fuel, usually about twice as many hydrogen as carbon atoms.. And in the air you get the Oxygen... so you end up with (for gasoline, or OCTane) 8 C + 16 H + 16 O => 8 H2O + 8 CO2 + energy Hydrogen weighs 1, Carbon weighs 14, and oxygen weighs 16 IIRC.. so putting the weights in there you get 8x14 +16x1 for the fuel, plus 16x16 from the air... = 128(fuel) + 256(air) => 144 (water) + 368 (CO2) Taking the ratio of 368/128 = 2.85:1... 7.2 lbs * 2.85 is 20.7, which is for gasoline... Diesel will be higher, but it's pretty close :) One thing I figured out is an engine like a Cummins 5.9 can use over 70 lbs of air a minute... put into perspective, that's more weight in air than what comes out of a garden hose!
